that's an overly simplistic approach.

the opps are going to be far less inconvenienced than partner. if they have a heart fit, they're very likely to find it. when you have a 3 card discrepancy between the 2 majors, there's little chance of their getting to the wrong major fit (yes they might have difficulty choosing between clubs and hearts but that's less important). partner, on the other hand, is rarely going to be investigating the spade suit on the off chance you've got AT98 so that fit's going to be lost.


Yes it's so much easier for them to find hearts and judge the right level over 3-P-5 than it is over P-P-1any :)

Side 4 card I do not mind. 4 card is a no no for me! With my own experience even if you have a fit, they will often have fit and missing the fit won't affect as much as missing a fit.

I hate being pre-empted by partner when I have a good hand and that always happens when I play in the forum indy. So I was somewhat surprised by the reaction of most of the posters. "Gross", "Weird", "Not enamoured", "Plain bad", "Never", "Not my style" are references to the 3 pre-empt. My initial view was that I would not open 3because I had a 4 card spade suit. Swap hearts and spades and I would. Nevetheless I recall Andrew Robson in "Partnership Bidding" arguing against restricting pre-empts to "pure". I have not found this reference after looking at his chapter on pre-empts. However I found this example hand recommended as a pre-empt nv in 1st.

Yes the 4 card spade suit he gives is much weaker than the one here. So is the objection by the posters the fact that the hand has 4 spades or is it the strength of those 4 spades?

Now on to the ATB bit.

The fact that West happens to have a 4 card spade suit is irrelavent to the outcome. Thus there is no blame to West for making the 3 pre-empt.

Easts 3N bid was semi-psychic (described as operating) but understandable since he had good reason to believe that the opps could make a major suit game and so could stand many off undoubled.

West's subsequent double of 5 was questionable. The double should be telling East that the 3 pre-empt had more defensive value than normal for this bid, in order to give East the best information for judging what to do next. In respect that West holds an outside Ace this is true. However, this defensive value could be partially or totally negated because East also hold a 7 card diamond suit and might have had just 6.

Easts subsequent pass of the double is way against the odds. East holding 5 card diamond support might just believe that the double indicates a 6 card pre-empt and thus if diamonds split 1-1 then there is a diamond trick available. Add that to the K taking a trick plus an outside defensive trick in partner's hand gives you 3 possible defensive tricks. But would you put your money on that? No way! East should live up to to the "stripey" that he was and retreat to 6. Yes he may well go for -500, which could be a small loss.

So West gets 25% blame for the double and East gets 75% for not removing the double of 5.

% 10 blame to East for having this West as a partner. Rest of the fault goes to West.

Comment by Wackojack that says having 4 card had no role in the outcome is at best funny. I won't even bother to tell why.

I have been known to preempt with a major on the side, but not often. For me, and apparently for others, it seems safer to do so when the major is hearts. Having four hearts is only a problem if partner has fitting hearts, and then since I have a lot of diamonds and together we have a lot of hearts, probably the opponents have a lot of spades. Not always, but often.

On this hand it would not occur to me to open 3D even if we switch spades and hearts. I am not interested in making a call that is apt to land us in a diamond contract when I have a strong four card heart suit (assuming the actual spades are the hypothetical hearts) and a diamond suit headed by the QT9. If he opponents buy the contract I am not interested in a diamond lead. If opponents bid a game and partner has to decide in taking a sac, I have misled him and he may well make the wrong choice.

I am not as opposed, perhaps not nearly as opposed, to preempts with a side major as Mr.Ace is but I do think a side major is a drawback and here I don't think it is even close.

But, mostly, I don't think ATB really applies here. Or maybe I should say beyond my reach. The style is, to my mind, wild and crazy. Wild and crazy can work. In a sense, it did work. They can make 6, they stopped in 5. But then there was the double.

So I would not have opened 3D, and if partner had opened 3D I would not have bid 3NT. It's difficult to meaningfully say who I would blame for the eventual result when I would not have made either of the first round calls. Anyway, I always interpret ATB not as a moral judgment but as a question as to how to do better. Here, they might decide whether (and sure, this is just my opinion but posting the hand requests opinions) the highly undisciplined approach works for them.

It's an entirely legitimate style to decide that by preempting with a wide range of hands in first seat you potentially mess up 3 people, and you're 2:1 that the person you mess up is an opponent. Not sure whether I would on this actual hand, but I wouldn't crime it if that's your general approach.


But one of those people has already passed.

I know its passe, but there's something to be said for a normal preempting style in 2nd seat.

Missed that. Then I don;t hate 3D quite as much, but with side spades its a poor call.

Not sure whether I would on this actual hand, but I wouldn't crime it if that's your general approach.

I am familiar with this argument, presented eloquently in an article by Marc Smith many years ago, but I am unconvinced as to its validity. Validity and legitimacy are closely tied. As long as the argument remains unsettled it remains legitimate.

There are essentially two options: a narrowly defined pre-empt or a widely defined pre-empt.

The principal benefit of the wide definition is increased frequency. Increased frequency is not of itself necessarily a guaranteed long term gain, but it is fair to acknowledge that the 2:1 ratio of opponents to partner contribute to this being of net benefit in the long term.

The principal benefit of the narrow range definition is that its contribution to partner's assessment of the combined potential of the hand exceeds that of the opponents, on the reduced frequency of occasions when it arises. For a given combined strength of your partnership's holdings , it is broadly irrelevant how they are divided between the partnership. Not entirely irrelevant, but close.

The question before you is whether the increased frequency of the wide range more than compensates for the loss of pre-empter's partner's ability to judge the combined potential. I have not seen a convincing argument either way.

Wow. This thread is just strange to me.

Let's start with 3. This diamond suit is often going to make 5 tricks in a diamond contract. Playing in a 4-4 spade fit, you'd often make 0 diamond tricks, and you wouldn't be surprised to make 0 diamond tricks in a 5-4 spade fit either (trumps splitting 3-1 and they get a force going immediately). To me, this is the prototype of a hand that I would open 3 in first seat and pass in second seat (though I am not sure the latter is right). Passing in first seat just because we are afraid of losing a 5-4 spade fit seems losing bridge to me.

Now to 3NT. In my view, there is not a single hand that would pass after (3) P (3N) and that would act after (3) P (4). The 3N psych is so frequent, and you have a better chance at finding your best fit over it (partner has a 4 cuebid available to find the right major fit, and you could get out in 4 if needed). Meanwhile, 3N also gives 4th seat the 4 cue to show both majors. In my view, this 3N psych is the dumbest frequently made bid in bridge.

To illustrate my point more:

Quote

btw i think the criticism of east is excessive. with 13 points the chances of getting 3NT under the radar are very reasonable, and whilst the undoubled penalty in 3NT would exceed the doubled penalty in 5D, that's because the hands fit very well and because west has such an atypical hand.

Sure it is true that 3N might go undoubled. But so might be 4 or 5! In fact, there are certainly hands that would pass a direct 5 that would act over 3N.

On to the final double. First, pass can't be forcing here. East had a lot of room to make a slam try over 3. We are never suddenly going to bid 6 in order to make it.
Having gotten that out of the way, what does East's pass mean? Surely, most hands that bid 3N and 5 to make would double. So for me the pass suggests either that East made the dumbest psych in bridge, or that his 3N bid was a bit of a gamble - say, QJx Kx AKxx Axxx. This hand is a legitimate 3N bid, a legitimate compete to 5, yet it doesn't expect to beat 5 if the opponents are serious and partner has no defense.

If you think East shouldn't make the dumbest psych in bridge, then the double by West is completely reasonable.

Heh, if it was not you I probably would have, but knowing how good player you are, and how you normally choose your sentences carefully to describe your opinion, I really took it as an overstatement, as I replied probably with a similar overstatement! Posted Image

EDIT: I like the analyse of forcing pass and final double though, most people misses it.

On a more serious note, can you give an example of a hand that, in your opinion, would act over 4D but not over 3N?

any 14-15 bal? and before you say there's only 1 diamond missing, i'd bet my house that the OP doesn't particularly expect 7, even missing the akj, considering his evident style.
