[inquiry]

First, only wacky system people need bother to read this thread, and even most of them may want to skip it. It will not interest most people. Another thread exist which discusses this topic (see Transfer Preempts)

This thread will discuss the way this concept has been evolving in my partnership with Misho. This is still a work in progress, so any input on how to improve it or any gapping holes will be appreciated. But don't make any suggestions that will affect the meaning of any of our two bids.

To summarize.
1) We can not preempt specifically to 3C.

2) Opening three bids:

• 3♣ either preempt to 3♦ or strong two suiter without diamonds (4 losers or less)
  
• 3♦ either preempt to 3♥ or strong two suiter with diamonds and a black suit
  
• 3♥ preempt to 3♠ or strong two RED two suiter
  
• 3♠ = any solid seven card suit, nothing on the side
  
• 3NT = any preempt to four of a minor

First area of problem, responses are cramped. If you want to "raise" the preempt, you had best have two places to play. For instance,

3C-P-4D <<--- Your partner may not have diamonds at all!!! So if you bid 4♦, you have to be prepared to hear partner bid 4♥ (hearts and a black suit) or 4♠ (spades and clubs). And bumping the preempt to the five level? Forget about it.

Second area of problem, when you have your own extra long suit.. and fear partner might have big hand with two five card suits for which you don't fit. We play simply bid the suit rather than complete the transfer. This doesn't work so well if the transfer suit is your long suit. More on these later.

The most common initial response is to complete the transfer. Opener's rebids are to show the type of hand held. Pass being the most common, showing the weak hand. Any bid other than pass (even in competition) shows a strong two suited hand. That is, if you open 3C/3D/3H with the weak hand, you are now out of the auction if partner completes the transfer or passes in competition. As responder, if you hold a fit for a possible strong suit (assuming partner has the two suiter) then you must complete transfer unless you are extremely strong. For instance, if partner opens 3♦ and you have diamonds, you must bid 3♥. If partner opens 3♥ and you have hearts or diamonds, you must bid 3♠. If partner opens 3♣ is a little more problematic. A 3M bid is more common now.

In principle the easiest two suiter to show is hearts and diamonds. You open 3H and then bid again, this is always hearts and diamonds. The minimum holding is 4 losers, and the rebid to show this is 3NT. There are three ways to show a three loser hand, all ending at or below 4H, which maybe the limit to the hand. These are, 4C, 4D, and obviously 4H. 4H shows a spade void (making cover cards easy to count, ignore those in spades), 4C could be club void or no void, I waffle on which is best, currently I play it as no void (so 6511 or 5521). 4D shows diamond void. Bids higher than 4H show fewer losers and voids or not.

The next easiest two suiters to show are those with diamonds and a black suit. You open 3D and then over 3H, you show your losers and your second suit. We use 3S here to be 3 or 4 Losers (3S rebids always show 3 or 4 losers, all others describe more or less precise number of losers). 3NT shows minor two suiter with 4 losers, a 4C rebid shows minor two suiter with three losers, higher bids show different two suiter with specific number of losers with or without know voids.

The most difficult two suiters to show are those starting 3C. 3C is used with any two suiter that DOES NOT INCLUDE diamonds. Our rebids are such that they show the next two suits. Thus, over 3C-3D, a 3H rebid shows hearts and spades and exaclty four losers. A 3S rebid shows spades and club with 3 or 4 losers. A 3NT rebid shows hearts and clubs with 4 losers. Higher bids show specific two suiters with different number of losers (for instance 4H would show hearts and spades, 3 losers, and 4S would show spades and clubs with 2 losers or the rare EXCEPTIONAL 3 loser hands with lots of extra chances).

I can provide the complete structure for all opener's rebids if anyone is interested. But here is where the bidding gets fun. The bidding will be at the three hearts or higher when you have a strong two suiter. What kind of sure covers exist?

A sure cover will be the AKQ in either of your partners suits, A side ACE if he has denied a void in a suit. That is it. But there are a number of "possible cover cards". These include such things as King in a side suit, doubleton in one or openers suit, and even five small cards in one or partners suit (doubleton and five if partner is missing the queen). We have devised a way to explore all these possible cover cards, and that is what I would like comment on.

These will be outlined in the next post.

[inquiry]

Reminder what we want to explore: What kind of possible cover cards exist?

• Five card support will cover for a missing queen (should you partner be missing it)
  
• A doubleton could cover for a missing queen (if you ahve adequate support in the other suit and your partner is missing it)
  
• A side suit king may be a cover or may not. An oddity, two side suit kings are never more than one cover card.. keep this in mind when bidding, one is always wasted.
  
• A side suit queen, while useful (say opposite Kx), is never a cover UNLESS your partner has a void and has specifically 5530 distribution.

We have developing a continuation scheme that allows responder/opener to explore which cover cards in responders hand are working and which are not. First, there is no BLACKWOOD (gasp). Let's look at the scheme.

After Opener shows his losers and his two suiter with his rebid, responder generally counts his sure covers, and bids to the appropriate level. Here is an example hand from a recent BBO event…

Of course, one hand doesn’t prove much, but here out of 33 tables, only one bid slam. Our auction would be quick and simple. 3D-3H-3N-5N-6D-Pass. Where 3N showed minor two suiter with four losers. Responder sees three cover cards and a fit. 4 loser-3 covers = slam. What could be easier? (Opener might want to consider not opening 3D with Kx of hearts instead of Ax, but it is possible to be off two aces here, but that hand would not be worth a three diamond bid with such a weak club suit.)

Sometimes, responder will not know. If he has a side king, is that a cover? If it is, he may have 3 covers and slam should be bid, if it is not working, he only has two and no slam. Sometimes he will have five small cards in support. Is that a cover for missing queen or not? How about a doubleton in one of the two suits with support for the other? On some auctions, even a side ace is not a sure cover. The answer to these questions could be the difference between game and slam and slam and grand slam. We address this with some "uncertainty" auctions.

So, after opener shows his second suit, if responder does not immediately place the contract, we are sure there is uncertainty. That is obvious enough. We express the most obvious uncertainty using the two cheapest bids in the non-anchor suits which not onlyy express uncertainty, but also DENY control (ACE or KING) in the bid suit..... Let's see how this works...

3C-3D
3H-4C <--- 3H shows heart and spade, 4 loser

4C denied a cover card in clubs, and expressed slam interest if enough cover cards exist in responders hand. 4C is neutral on location of any other cover cards (but very unlike to have three sure covers in the majors or would jump to slam). Ok, one thing is easy, opener can bid 4H if he has two club losers, as pass/correct. Any bid other than 4H (the cheapest anchor suit) is encouraging by opener. The cheapest of these bids ask about the other side suit (here diamonds), other bids show disintrest in the other side suit and express other concerns.

Alternatively,
3C-3D
3H-4D <<---- 3H still major two suiter with four losers

Here, 4D denies a control in diamonds, and by inference, includes a control (A or K) in clubs (since you didn't bid 4D). We use 4NT rebid by responder to show 2nd round control in the higher of the two side suits, and if the lower suit was bypassed, it promises control there as well. If responder bypasses 4NT and both off suits, to cue-bid the cheaper off suit, it promises king in the bid off suit, and A in the higher offsuit.

Opener, hearing responders off suit controls (or lack there of), often knows where to place the contract. One of the major problems he might have where this is not true is where he has a singleton in the other side suit when responder promised a control there (say by bypassing it). Now the king of that suit WILL NOT BE A COVER CARD, while the ace will be. This is such a concern, we reserve a special bid for this case. After responders off suit bid (which can include 4NT), the cheapest non-signoff by opener express doubt that the other suit control might be useful. This means, discount the king in the offsuit. Let's continue with an example...

3C-3D
3H-4D <-----Here 3H showed a major two suiter with 4 losers,
4H-4S
?

4D DENIED a diamond control (ACE OR KING), but promised a club control (ace or king, because without a club control you would have bid 4C). Over 4D, 4H by opener would have been signoff (pass/correct), so 4S is the next cheapest bid. This is an uncertainty bid to allow responder to evalaute his club control. The king here is no longer a cover card or opener would have bid more than this. So if responder had two sure cover cards plus the club king, the auction ends here (or in 5H).

Opener often might have Ax of Kx in the off-suit responder promises something in, and will know full well that what ever responder has in it, it is working. In which case, he will not bid the uncertainty bid, nor the signoff bid. This leaves room for opener to express where five card support or a doubleton will be of use (suit without the queen). These suits without the queen bids are quite useful. On the above auction, 4S was uncertaintly about clubs, so 4NT is one suit without the queen (hearts=lower) response, 5C is the other (here spades), and since room allows 5D to show both or to ask for third roudn diamond control. This is unclear right now what is best.

So this allows you to find side A/K. doubletons where they help or in the same suit where doubleton helps, when a five card suit will help be a cover card.

Since opener with no question about the side suit can express suits where five small or doubleton will help, when he expresses uncertainty with the second cheapest non-signoff, responder with an ACE in the suit, can 1) Leap to slam, 2) show suit where he has EITHER five or two card support (with two, then real support for the other suit), 3) show AK in the other side suit).

The concept here is that if you made a slam try, opener expressed doubt your side suit control was useful. If it was useful, and that gave you enough cover cards for slam, you would bid it. To not bid slam suggest one of responders cover cards may or may not be working. Since we KNOW AKQ in both partners suit are working, and we know the ACE in the side suit is workng (due to the uncertainty ask), the "iffy" cover card will always be either long support (maybe JTxx or any five) for one of the suits, or doubleton for a suit with adequate support for the other. So responder uses exactly the same bid opener would have used to show these hands... for instance,

3C-3D
3H-4D <<--- 3H showed major 2 suiter, 4D denied D, promise C control
4S-4N <<--- 4S showed concern about King of clubs,

Here 4N showed CA and either 2 hearts, or five hearts. The concept is if you are missing the heart queen, responder wants to bid slam. Note, responder might have club king and five hearts, plus maybe heart King and spade Q. Since heart King and spade queen are working covercards, if the fifth heart covers for the missing queen, slam is assured anyway. So obviously responder need not signoff. Likewise, responder may have club ACE, five hearts to the king, and the spade Q where if you show the fifth heart is a cover card, grand slam can be bid, otherwise, responder stops in 6H.

When opener promises a void, all off suit bids are about the non-void side suit and investigating rather xx or xxxxxx in an anchor suit is a cover card.

Let’s look at one more recent hand…

Only four out of 22 pairs found slam, no one found the excellent grand slam. How might this go playing the strong transfer preempts?

Auction one.
3C - 3D
3N – 4S <- - 4S promises A or K of diamonds, denies spade control
5D - 6C
Pass

5D shows no concern about the diamond ACE (it actually covers 2 losers, the 2nd spade!!). So now grand slam can almost surely be bid. Problem is the heart queen isn’t worth what it use to be worth. 5D shows need help in hearts, the queen is missing. North with K stiff, knows this one is working for two covers, the diamond ace is working, but he hasn't been able to visual a fourth cover card. It is still too much to ask him to bid the grand slam, but when he bids 6C, south must know that 7 in close. Responder didn’t bid this with two covers. The diamond ace is one, he has no other in diamonds, and he has none in clubs. Qxx or Kxx of hearts is only one. So he rates to have Kx, K, Q, Qx, or KQ(x) in hearts, nothing else makes. So 6C will be bid, and opener will at least consider grand slam here.

This system, however, actually allows you to find the grand slam when played as described above. All opener need do is bid 4N to ask about the diamond ace (which he knows responder holds), responder would not bid 5C or 5H (since we all know he holds the diamond ace). Instead, he might just leap to slam, or he might explore grand slam/slam possibility with a bid showing either five hearts or five clubs, or a doubleton club or doubleton heart. When showing either of these, he will not hold the Queen in that suit. So over 4NT (which ask for info on the promised diamond control), responder would have bid 5S showing either five hearts or doubleton heart. If doubleton without the queen. Since he will not have enough cover cards when missing heart king when not holding heart queen, Responder can bid 5NT (pick slam), and when responder picks clubs, he can confidently bid the grand slam. Responder can also bid 7C if he likes, as responder would have to have Kxxxx of hearts or Kx of hearts. He would correct 7C to 7H with five of them.

Ok. Can you really play with Blackwood (see the 6D hand above)? Does showing side suit kings, and five card and two cards in anchor suits really work? Can you find an improvement?

BTW, same exlusion bid, etc apply to higher responses... if 4NT is not available, then 5NT serves the roll of 4NT on lower auctions (king in higher side suit).

[inquiry]

This is just too good.. so I have to post this. Of course this is not a terrible difficult hand... with any method. This was played just now in Topflght. Almost all pairs were gold stars, as can be seen from the results here...

Scoring: IMP

West North East South

 -     -     -     3♦
 Ps!   2♥l   Pass   4NT!

4NT is minor two suiter, two losers, spade void. looking at two aces, grnad slam is assured.. just want to find best, so 5NT is pick slam then raise to seven. If they double, you can redouble and hope no club ruff.



As you cansee all these great players reached at least slam, and five of the seven reached grand slam, with some struggles.
6DE+1      -940      10

[inquiry]

Ok, some real world hands with results from the tables.
Remember.. I haven't given the full opener rebid schedule, generally the higher the rebid, the fewer the losers. So if opener rebids at the six level he is showing one loser and some very spefic distributions. If he rebids at the three level he is showing 4 losers (3 or 4 if he rebids 3s), and at the four level, generally 3 losers (4S shows two), etc.

Responder bids a new suit after opener shows his two suiter DENIES control in that suit, and if a suit was skipped, promises a control in the other suit. Opener can try to signoff if control in other suit is wasted or he can explore if responder has ACE (or king) in other suit. In addition opener can ask or responder can show a pseudo or substitute queen in either anchor suit (xx with adequate support for other suit or five card support missing the queen for an anchor suit).

Once side suit ACE/Kings are known, only final question to how high to go is if a pseudo queen in "working" or not.

Let's look at an example.

Opener can issue a pick a slam request here because [
  1) partner's heart king is working (he promised heart control and I have ACE), &
  2) Partner will have either two other sure working cards for 4S, or
  3) Parnter will have one additional working cover card and a possible cover card in the form of a doubleton without queen in one minor and legnth in other, or
  4) Partner will have one additional cover and five cards in one minor without the queen, or
  5) Partner may have five cards in one minor without the queen and doubleton in other without the queen
  6) Partner may have xxx Kxx AQxxx xx, or xxx Kxx Ax Qxxxx

Condition 3 the doubleton serves as a "replacement Queen" in the doubleton suit. Condition 4, the five cards suit serves as a "replacement queen" in the long suit. IF partner has condition 2, we will reach our slam. If partner has condition 3, we will reach 6 of the suit partner has support in. If partner has condition 4, we will reach six of the suit partner has five card support without the queen. And in condition 6, we will reach grand slam in the suit partner has five card support in. As you can see, many reached this excellent slam. Question becomes woul dthey have reached the grand slam if condition 5 or 6 existed?

Let's look at another one.

=======================================

I hope you see how the 5NT jump confirmed both queens missing, and we can make which ever slam you want to bid. With both queens missing, which ever pseudo queen responder was relying on (if he was), was working. Tell him the good news. This leads to some magic grand slams, as example 5 and 6 above shows.

(see example auctions later where WEST does not go quietly)

3D = heart preempt or strong two suiter with diamonds and black suit. West might find it difficult to bid immediately.

3N = minor two suiter, 4 loser. Here WEST finds his voice, with 4D shows majors.

4H = no heart cover, slam interest. I can count at least three potential cover cards.

4S = making it "tough for us", but we are already in slam try auction

Pass over 4S = First step, asking for nature (if exist of spade control), here as always the request is looking for ACE.

5S = spade ACE and two pseudo queen's. If I had spade ACE and two solid minor covers I would leap to slam. IF I had spade ace and one pseudo queen, I would bid 4NT. Opener would 5C only if pseudo queen in clubs does not work (in other words if opener has club queen). 5D only says pseudo queen in clubs does not work, and is neutral on diamonds. If either pseudo queen works, then over 4NT opener would bid beyond 5D

6C = we are off heart ace, so slam is limit

6D = ok, let's play in the right strain, which is diamonds

Only two pair found this slam, in part because of the michaels cue-bid they faced. LHO has trouble bidding over 3D since opener COULD have hearts. So here, I had him pass timidly. Below we will see a more aggressive approach.

=======================================

Imagine WEST could DOUBLE 3D or bid or bid 3H/4H to show major two suiter.

3D - (x) - P - (3S) <<--- this is "support" so doubles by opener show other 2 suiter
X - (4S) - 4N - (P)
6C - (P) - 6D - (all pass)

Over the interfernce here, since they are supporting each other. Dbl of 3S show minor two suiter, 4 loser, 3N shows minor 2 suiter 3 loser, 4C shows minor two suiter, 3 loser, void in lower suit, 4D shows minor two suit, 3 loser, void in higher suit, 4H show 2 loser, heart void, 4S 2 loser, spade void, 4N two loser no void, etc.

This auction has managed to effectively crowd your auction. If WEST passes 3Sx, then partner will bid 4H and proceed normally. Over 4S, north can make forcing pass then invite with five diamonds. But here north bids 4NT. This still does not ask for ACES, but rather shows spade ace. When they are bidding a suit, there is no need to show the normal "second round control". So 4N show first round control in their suit. Opener with heart control takes his best shot. This is more of a gamble than when they stayed out of the auction. But their bidding is not so clear.

Seems this thread is only interestig to a few. but if you run across any hands like this and want to discuss them, private message me. Also, I am willing to share my bidding notes and hundreds of example hands in lin file format if anyone is interested.

On most tables 3♥ will end the auction, but you open 3♦ pass 3♥ pass pass DBL pass pass pass.

You are correct. should I choose to open 3D, partner will bid 3H. On this death layout, and iwith diamond ace lead, and spade switch, I will win only five tricks (1S and 4 hearts) for -800 versus their 3NT game. The rule I use for preempt, as quoted in this forum a lot of times is 5421 (down five in my hand at favorable, down four if neither vul, down 3 if both vul, down one at unfavorable, at mp, I switch to 5431) . So when I am not vul they are, I will open this hand 3H (I have 5 winners, as opposite nothing I will win only 5 heart tricks. Turns out with this split I win only 4). At the vulnerabilty you gave, I will not open this 3H, but that is just me. Make EW vul, and I will bid 3D. Ok?

However, the question becomes what your opponent's agreements are. Let's consider their options (they really need to be able to discuss this, it is hardly fair to spring this on them unawares, but more and more people are opening some form of transfer preempt).

The options are,

Over 3D, a double shows diamonds.
Over 3D, a double shows a takeout double of hearts
Over 3D, a 3H bid shows a strong stake out double of hearts
Over 3D, a 3H bid shows hearts
Over 3D, a 3H bid shows a two suiter, spades and a minor
Over 3D, a pass is "waiting" and when 3H comes back around now dbl is takeout
Over, 3D, a pass is waiiting and when 3H comes back around double is penatly.

These are somewhat mutually exclusive. If they save 3H to show hearts, they will lose the opportunity to use 3H as takeout. If they don't have 3H showing hearts, they lose the oppotunity to interfer with your strong hands when they do hold hearts. If they use 3H to show micheals, they lose the ability to show hearts or use 3H as takeout. IF they use double of 3D as takeout of hearts, they lose the abiity to show diamonds with the double, and vise versa.

Clearly, you draw the assumption that over 3d, pass is waiting, and when 3H comes back around, double is penatly. That is certainly playable, and I am particularily fond of the pass and then act with no clear direction. So I like the pass here followed by the double to penalty oriented, "cards". However, on this hand, I will be no worse off than the people where the auction goes 3HppXppp, of course. And many (not all), will REOPEN with double with EAST's cards. Let's say half the field does so. I will get 25% for this bid. It will be slighlty higher becasue some (gasp) will open 4H with south hand or north willl take a call. How will I do at imps? I am minus 800 versus a vul 3NT that makes (for minus 600). And I was mildly unlucky. First the opponents had a way to play 3Hx as penalty (at a cost of using either an immediate 3H bid as takeout.. which means I will never face the 3H-X-all pass auction on other hands), or they use 3D-x as general takeout, which means they can not make use of lead directing or sacrafice suggesting 3Dx to show diamonds.

This defensive method leaves them at some considerable risk on other auctions, but then, there is no perfect defense to this transfer preempt that shows the transfer suit weak, or two other suits strong. Each defense you choose will work on some hands and not on others. It might be useful to discuss what the best approach to transfer preempts are. IF the SUIT bid is absolutely promised, I see no harm in cue-bid being general takeout, but I play if they cue-bid the suit, double by responder shows penalty double of the bid suit (consider it a raise), this can lead to some penalties when opener has the strong two suiter without the transfer suit.

in my opinion this is definately a brownsticker convention, good for this site and
A-Level tourneys, but not allowed in 90% of the tourneys all over the world. as far as i know (and i play X-fer preempts with str 2-suiter option as well) wbf calls this a hum convention as long as no anchor suit (dont know the precise technical term in english) is announced.

While you are entitled to your opinion, the regulations state otherwise

Quoting the WBF system policy as published at http://www.worldbrid...tems/policy.asp

2.2 HUM Systems

For the purpose of this Policy, a Highly Unusual Method (HUM) means any System that exhibits one or more of the following features, as a matter of partnership agreement:

1. A Pass in the opening position shows at least the values generally accepted for an opening bid of one, even if there are alternative weak possibilities
2. By partnership agreement an opening bid at the one level may be weaker than pass.
3. By partnership agreement an opening bid at the one level may be made with values a king or more below average strength.
4. By partnership agreement an opening bid at the one level shows either length or shortage in a specified suit
5. By partnership agreement an opening bid at the one level shows either length in one specified suit or length in another.

EXCEPTION: one of a minor in a strong club or strong diamond system

Its also worth noting that this premptive structure does even not qualify as a Brown Sticker convention since the "Weak" option always included 4+ cards in a known suit. Quoting the same page

2.4 Brown Sticker Conventions and Treatments

The following conventions or treatments are categorised as 'Brown Sticker':

a) Any opening bid of two clubs through three spades that:

i) could be weak (may by agreement be made with values below average strength) AND
ii) does not promise at least four cards in a known suit.


EXCEPTION: The bid always shows at least four cards in a known suit if it is weak. If the bid does not show a known four card suit it must show a hand a king or more over average strength. (Explanation: Where all the weak meanings show at least four cards in one known suit, and the strong meanings show a hand with a king or more above average strength, it is not a Brown Sticker Convention.)

EXCEPTION: A two level opening bid in a minor showing a weak two in either major, whether with or without the option of strong hand types, as described in the WBF Conventions Booklet.

The ACBL must be way ahead of the curve then, I quote the following from the ACBL Mid-level chart, under the heading:

ALLOWED ** Unless specifically allowed,
methods are disallowed **

7. A transfer opening bid at the two-level or higher showing a weak bid in
the suit being transferred to or a type or types of strong hand.

So this is hardly "brown sticker" (aka highly unusual) if the ultra conservative ACBL has it as mear mid-chart. The transfer opening bid occurs at the three level (thus 2 level or higher), showing a wek bid in the suit being transfered (the next highest suit), or a type (not types) of strong hand (in this case two suiter).

Here is a link to the ACBL convention charts, you will need adobe acrobat reader on your computer to read this file. http://www.acbl.org/...nvchart2005.pdf

Ben,

I am finding this thread quite interesting. I would like to see more hands where:

1) Opener has a three-level prempt
2) Responder has a preeptive raise of a three level preempt but opener is strong.


I particualry wonder about the last with the 3C opening when the auction would go 3D-5D with natural preempts.

[Gerben42]

I agree you need to talk through a defence to this system, that is probably why it is MidChart in the ACBL. Not that any MidChart conventions are considered out of the ordinary for std. European tournament play...

In Europe where there are less rigid restrictions I would expect every serious pair to already have a defence to this as soon as you arrive at the table. Same for Multi and assumed fit preempts.

A good starting point would be that after 3♦:
a) Double is takeout of Hearts
Pass then double is Penalty
c) 3♠ and higher as after a normal 3♥ opening bid.

Now you can discuss what (3♦) 3♥ should be. As I play Leaping Michael's this asks for a stopper for 3NT.

Few comments

1. There are example of conventions permitted by the ACBL Chart that are also classified as Brown Sticker Conventions by the WBF. A 2NT opening showing a weak 3 level preempt in Clubs or Diamonds is the most obvious example, however, there are others. In short, I think that your argument is flawed.

2. Brown sticker is not equivalent to a "HUM"

3. Try to avoid using word's Highly Unusual in framing these types of arguments. I consider it very unfortunate that the WBF chose to use the expression "Highly Unusual". In doing so, the suggest that the primary issue is related to the frequency with which player encounter said methods. If you look at the definition of a HUM, its celar that HUMs are characterized by either

a) Strong pass and weak 1 level openings
B) Multi-meaning 1 level openings (for example, a 1♠ opening promises 0-2 Spades or 6+ Spades)

Using the expression Highly Unusual leads players to believe that methods that are not standard are HUMs...

Total rubbish! The anchor suit is only needed for a weak version, so the preempt suit is known (transferred). Apparently you need to read the rules, because you don't even know what kind of system YOU play.

[Gerben42]

Now that we had the possible disadvantages, I think that there is great advantage in showing these 5-5 hands like this. They need very specific values for high-level contracts so they require special attention which most systems cannot cope with.
So I like the idea

Before we show some hands were responder wants to or actually does raise the preempt (and there are hands where this is a good idea). Let's review a few rules.

1 - If opener is WEAK, he is not allowed to bid again after the three level bid. If he wanted to preempt higher than three he should have done so at once. So futher action by opener shows the strong variety.

2 - Doubles by either partner of an unsupported overcall are penalty oriented. Clearly if opener doubles this means this is one of his two suits

3 - Doubles by opener after they have raised each other (either overcall and raise or takout double and raise, or takeout cue-bid and raise), show the other suits (whatever strong two suiter he can hold). And, DOUBLE here is the WEAKER of openers options. (But opener's doubles double of "his transfer suit" shows most difficult to bid two suiter, since when strong, can never have that suit). The exceptions are these bids...
 3C=(DBL)=Pass-(3H)-DBL = at three level, shows hearts and aother siot, strong. 3S shows spades and clubs (4Losers), 3NT shows spades and clubs (3L), etc.
 3C=(DBL)=Pass-(3D)-DBL, here this shows hearts and clubs, 4 losers. This way it is possible to play 3Dx and 3H. 3H over 3D is still major two suiter, 3S over 3D is still spades and clubs, This allows 3NT to be 3 losers instead of four with hearts and clubs.

4 - At higher level, double show their suit (or if they raise), four losers. Bids show two suiter, fewer losers. The type of bid shows different loser... one example..

3C-(3S)-P-(4S)

Dbl = 4 losers, some exceptionally bad 3 loser hands, clubs and heart (3C can never hold diamonds)
4N = 3 losers, clubs and hearts
5C = 2 losers, clubs and hearts, etc.

Next time, over interference, examples.

[inquiry]

The following three hands are just the first three I downloaded... that competition would be expected. On the first, a very slam and possible grand slam failing only on 4-1 diamond split as missed at every table. A typical auction is shown as well as all the results. On this first one, the auction would be...

3D-(4H)-Pass-Pass
DBL-(Ps)- 4N - Pass (Opener can't have hearts, when strong, so DBL = 4loser)
6C-(Ps)-Pass-Pass (6C shows hearts under control, good hand for dbl)
All pass

The 4NT bid is necessary, because of uncertainty on this auction. If openers suits are known, 4NT would convey specific control meaning. Here it is a type of "slam try". Note, 4S would be pass/correct suggesting no diamond support. Opener passes with spades, and bids 5C without them. Here, 5C would be odd, as it shows no desire to stay at the four level in spades, no willingness to play 4Hx, and no diamond support. So in fact, 5C should show slam force if opener has heart control and spades. So 4NT denies the heart control here, but shows some willingness to move towards six.

With hearts under control and Ax of spades, opener should shoot the slam, I think, but at very least you get to cold five clubs, instead of 4Sx.

=======================================

The next one, below, takes advantage of the fact that when opener opens 3H, his only strong two suiter can be both red suits.

Our auction would go...
3H - (4C)- Pass - Pass
4D - (Ps) - 4H/5D - all pass

Hee, over 4C, opener can NOT have clubs and hearts (would open 3C).
So double does not show clubs and hearts. Dbl shows red suits and 4 losers.
Opener didn't double, so is 4D bid shows red two suiter with 3 losers. Responder has (luckily), two winning options. He can bid 5D which is fortunate it makes. Or he cand bid 4H, which is equally fortunate it makes. Clealry responder is not thinking about bidding higher. Also note that opener can with 3 losers sometimes choose to double instead of make the cheapest bid to show the 3 loser hand. This is hand falls into that category. 4Cx would be nice result too (down four).

=======================================

Next hand, after three passes, you must always think this might be strong. Here West does and steps in with a 3S bid... (auction given in the quote). In balance seat, dbl would be spades is one of my suits, so 3NT is still 4 losers, minors, so that 4C is 3 losers, minors. North with two minor honors can do the math, 3 losers, minus two covers = slam. With four clubs, he can even try grand slam if his doubleton diamond Kx is good for two covers (his partner missing the queen). The Bid here is back to normal. 4H denies heart stopper (we know the suits), neutral on spades (he is bidding slam always, question is five or six)

Over 4Hx, pass would be first step. Redouble (since can't want to play hearts) would be second step, 4S would be their step and 4NT would be 4th step. PAss would ask about spade control. Redbl would look for pseudo queens in general (4S would show one, five spades, two), 4S would ask explain club queen missing, 4NT would show diamond queen missing. The 4Hx helps a lot. Responder knows the diamond Kx is only one cover, so he bids the slam.

If RHO had not doubled. Opener would have bid 4NT (skipping spades), to say, I don't care about any potential spade control you have. Do you have any pseudo queens? North has real queen of clubs (yeah), but has pseudo diamond queen. The bids here would be, 5C/5D = no fake queens and only one cover (spade king, if held not counted), 5H = one psuedo queen with enough covers already for six (5S would ask), 5S = two psuedo queens, 5NT = pick slam, 6C/6D enough for slam, no pseudo queens. Note over the pseudo diamond queen showing bid, opener just signs off, this doesn't really help since he has the queen AND BECAUSE the ace of hearts is missing.

======================================

Does this really work? Find your hands and we can discuss them. Next when partner "raises the preempt"

Ben

[inquiry]

Here are some where you get the hankering to raise your partner's preempt.

Scoring: IMP

West North East South

 -     -     -     3♦
 Pass    4♥ Pass  4NT
 Pass   5♠    DBL Pass
Pass    5NT   Pass  7♣
 Pass  Pass  Dbl   Pass
 Pass  Pass  

4H was preemptive raise. Raises or fine when you have support for one of partner;s suits wehn he is stong. You don't have diamond support (one of his suits), but you have support for both of the others. Here, partner bids 4NT to show clubs, AND 3 or less losers. Responder with heart ACE, five clubs, and singleton diamonds, hopes at least one of these is working, so bids 5S (denies spade honor). Pass of 5Sx is first step, looking for heart ACE. without heart ace, responder would sign off. With heart ACE, he can bid 5NT to show a substitute queen (only because no room.. When responsder bid 4H he had a second suit in mind) . Opener doesn't care which substitute queen responder holds. IF partner has two diamonds, grand slam is great bet, with two clubs, he must have three or more diamonds, so same thing. With diamonds responder would correct to 7D.

This one is a little more frightening. If you bid 4H, you will play 4S when your partenr doesn't have the week hand. You could bid 3H and maybe get out in 4S. Turns out 4S is on ice, and this is the type of "exceptional 3-loser" hand that is upgraded to 2 losers for 4S rebid. So 4S is reached either way.

Scoring: IMP

West North East South

 -     -      3♦    PAss
 4♥    Pass  4♠    Pass
 5♣    Pass  6♦   Pass
 Pass   Pass 

Here you can freely raise to 4H. If partner has the big hand, you have a super diamond fit. Five clubs shows heart ACE, no club control slam try. With heart king, would bid 4NT, with no heart and no club control, would bid the appropriate level based upon cover cards. Six diamonds seems to be the limit anyway. Even 5D is much better than the field did. West should probably just bid 6D, and hope spade void, five diamonds, and heart ACE are all full covers. 5C is a way to check not two quick club losers and that the heart ace is working.

 Pass  4♦  Dbl  4♠
 Pass Pass  Dbl  Pass  Pass
 Pass  

Here you can raise diamonds, because you fit whatever major partner might have. IF hearts, your queen is working, if spades, you hope your fourth spade or short club is working. Once again 4S makes. And once again, if you bid only 3D, you probably will be in 4S anyway. PArtners 3S bid will not be forcing, but it is never passed with good fit.

As you can see...

To raise preemptively, you should be prepared for the most logical run-outs. And when you raise preemptively wiht goodish hands, you make the auction much harder on yourself. So the trade off is when you are weak and don't raise preemptively, you give them more room when partner is weak. This is true. But if you are weak and partner is weak, well, they were likely outbidding you anyway. Those hands still have to be examined.

I admit to having some degree of skepticism regaridng the xfer preempt scheme...

The system violates one of my fundamental "Laws" of preempting: Partner should always be able to pass a premptive bid as to maximize the pressure on the opponents. Systemically, opening ♦ when you hold hearts is a big loss. I readily admit to blatant hypocracy given that MOSCITO uses Xfer openings for limited 1 level openings. In my defense I will only note the following:

1. I believe that partner will advance over a MOSCITO 1♦ opening showing 4+ Hearts much more frequently than over a weak level Heart preempt. The losses are smaller.

2. The Xfer opening produces some very big wins. most notably: We are able to align the opening level with the frequency of the bid (critical for relay methods). Equally significant, the transfer rightsides many contracts.

My gut tells me that slam invitational 5-5 hands just aren't frequent enough to justify the systemic loses when you hold a "normal" weak 3 bid. I'm sure that you get great results when these hands come up, but what's the frequency, (Kenneth?)

[inquiry]

I admit skeptism at first as well. The reason being that misho wanted 2NT, 3C, 3D, and 3H all to be two suiters or transfer preempt. I was not willing, in final analysis to give up normal 2NT opener.

The tradeoff, which you can see above, is some uncertainty when clubs is opened as to the two suiter. And a HUGE TRADE OFF, I feel obligated to point out again, now way to preempt in clubs below the four level.

Anyone who says they want to keep the ability to preempt 3C so throw this whole thing out has my full support. That is surely a fair reason.

To keep it the competition thing seems a minor point to me, as does most of the raises. What I miss most is 3Clbus. That is a biggie. It just seems the wins, and at imps, the size of the wins, when you have the strong two suiter out weigh the loses.

Readily admit that you have good results when you're dealt 5-5 hands, however I'm skeptical if the frequency is sufficient to outweigh all of the loses...

Any complete analysis requires that you be able describe:

1. The frequency of the strong 5-5 hands, along with your expected gain compared to standard methods
2. The frequency of the weak 3 bids, along with your expected loses compared to standard methods

Have you done any type of analysis that will shed light on this issue?
