Some easy bidding sequences can be a surprise because you didn't agree it with your partner:
1) (3X)-Pass-(Pass)-3NT
    (Pass)-??           What do you play here?
2) 1NT-(2♣-nat)-3♥-Rubenshohl transfer-(Pass)
    3NT-(Pass)-4♥         4♥=retransfer ♠ or ♥?
3) 1♠-(Pass)-4♥?          4♥ to play?
4) (1X)-DBL-(REDBL)-Pass?     No preference or to play?
5) Jumps after opps opened a weak 2 or multi 2:
  5a) (2♥)-?           Difference between 4♣/4♦ and 4♥?
  5b) (2♦ multi)-?         what is 4♣/4♦?
  5c) (2♦ multi)-pass-(2♥)-?     What is 4♣/4♦?
6) Opps opened a multi 2♦:
  6a) (2♦ multi)-2♠-(pass)-3♥/4♥    Natural ♥ or not?
  6b) (2♦ multi)-2♥-(pass)-2♠/3♠/4♠    Natural ♠ or not?

after the 3NT rebid or overcall I play 4♣ stayman and everything transfer, suboptimal since you are transfering to an impossible suit with no meaning but at least its sound.


About hearts then hearts, it is natural, don't retransfer on competitive situations ever, except when the second suit its impossible

[Ant590]

Two come to mind...

(1) 1♠ -- 4♥
(2) (1x) -- dbl -- (rdbl) -- pass

If you have Both majors, could you not have started with 4♣ iso 3♥?

1) (3X)-Pass-(Pass)-3NT
(Pass)-?? What do you play here?

I play transfers, transfering opps suit is stayman. It's simple and applicable to all NT overcalls. Only problem is when X=♠, since we lose our stayman at 4-level. 3NT overcalls however can be offshape, so this method may be suboptimal to say the least.

2) 1NT-(2♣-nat)-3♥-Rubenshohl transfer-(Pass)
3NT-(Pass)-4♥ 4♥=retransfer ♠ or ♥?

For me 3NT shows a ♠ fit and minimum, 4♥ is cue. With both Majors we can start with 1NT-2♣-4♦ (4♣ = ♦+M).

3) 1♠-(Pass)-4♥? 4♥ to play?

I play this as 12-14HCP, singleton ♥, 4+♠.

4) (1X)-DBL-(REDBL)-Pass? No preference or to play?

Pass is no preference.

general rules overrule exceptions, it avoids critcal damage if you forget. So if he cannot be 55 he will be 64, and if he isn't at least you ain't play something ridicoulous.

I agree, it is very good to have a general rule.
In this case it is for you?: No transfer in competitive bidding, except if explicitly agreed. (e.g first 3♥ is transfer because agreed to play Rubensohl).
Remark: This 4♥ bid was done, without explicit agreement, by another pair at the club yesterday. It was meant as retransfer but passed by partner

I believe strongly that (4) should be "to play."

When their suit is a minor, this situation actually comes up with reasonable frequency. Typically advancer has five-six cards in their minor and a scattering of values, and 1mXX is going for a big number, whereas if our side runs to our "best side suit fit" we are the ones going for a number. This is potentially a huge swing! I have already won a number of boards because of this treatment, including a tie for top in this year's platinum pairs defending 1♣XX. One of my partners has looked at a large number of hands from top-flight play and identified this particular situation as one where many top pairs have the "wrong" agreement (pass=scramble) and lost substantially for it.

When their suit is a major, pass "to play" tends to have less utility. However, it is very easy in that auction to play 1NT as the "scramble" bid, since its natural meaning is somewhat nonsensical and our fit is going to be at the two-level anyway (guaranteed over 1♠; over 1♥ I would tend to bid 1♠ if that's an option since opponents are much less likely to double 1♠ than 2m). I suspect that pass "to play" would be more useful against certain styles of four-card majors, and I'm not particularly interested in having different agreements about this relatively rare auction over 1m, 1M showing 5, and 1M showing 4.

Interesting points Adam.

[Mbodell]

1) Natural I think, but am not sure.

2) ♥, we don't play retransfers, especially when the natural bid could be useful.

3) 4♥ is not to play, 2♥ is a forcing heart bid so we don't need this to be hearts. For us this shows a spade raise with a club void.

4) This is to play if X is a minor and no preference if X is a major (opposite a 5 card major system).

5 a) undiscussed. I'd assume 4♥ would be stronger and would likely not have a ♥ loser.
b and c) whatever is in ACBL defense 1. I'd assume leaping michaels but I forget if it is unknown major or a specific known major. We, unfortunately, almost never play against multi.

yes, that's my general rule if something can be natural in competition it must be.

I don't like retransfers in general, to me the biggest advantage of a transfer is to have a sure rebid, not to make someone declare, having a retransfer you later have 2 bids for the same purpose wich its suboptimal IMO.

[P_Marlowe]

#1 System on (Stayman, Transfer)
#2 We dont play Rubensohl, but if, than 4H would be 5-5 in the majors
#3 splinter
#4 no preference, I know, this means they can make a psych X, but who
cares, and if the X occurred in 3rd or 4th seat, we ar most likely to be
out gunned anyway
#5 Leaping Michaels, 4H is Michaels, more distributional than 3H, make it 6-5,
of course it may make sense to play the cue as both minors, but since we
play the unsual agreement, that Leaping Michaels is NF, ..., sometimes you
need a forcing bid (5a,5b)
5c is unclear - it is not Michaels, not discussed, and hence should not show
up on the table

With kind regards
Marlowe

Interesting point, Adam.

Over a major, having both pass and 1NT for scrambling has some use: 1NT for minors, pass asks doubler to bid the other major if he has four of them and no 5-card minor. Or something like that.

So I am skeptical about 1M.

As for 1m, it happens quite frequently that I wished that I played pass as penalty. Obviously the scrambling pass comes up frequently also, but probably in most cases we could manage without it.

Here in Acol-land, the trap pass occurs more often against 1M than again 1m, of course.

1) I play natural here, 4X being staymanish, but transfers would certainly be better after a reopening 3NT.

3) Strongly prefer natural. The hand type for a direct 4M bid comes up a lot, and it's very nice to be able to show it immediately. We don't badly need yet another way to raise spades.

4) Has always played this as scrambling and wouldn't really want to change. Disagree with others that 1NT is nonsensical as natural just because there was a redouble.

5a) 4m is leaping michaels, 4♥ good both minors (4NT bad both minors). It's probably better to play 4♥ as a good 4♠.

5b) 4m is leaping michaels with hearts. That suit is more easily preempted, so we are in a hurry to show it. As I play it, pass then 4m is leaping michaels with spades, but it could get ugly if the bidding comes back at a high level.

5c) I have no agreements, so the default of "natural" applies. I would probably prefer to play it as hearts + that minor.
