After 2NT-3♣; 3♦-3NT, if opener is (32) in the majors, you can't find out if you have a fit below 3NT.

Over 2♣, 2♦ is to play.

Over 2♣ or 2♦ we play uvu, so 2♥ shows clubs and 2♠ shows diamonds, Inv+, and double is to penalize.

Over 2♣, 2♦, and 2♥, Lehbensohl is on: 2N relays for a signoff. Direct 3m is invitational. A direct 3N denies either stopper; 2N then 3N shows both stoppers; 2N then 3M shows a stopper in that major and denies a stopper in the other major.

As for the why, it's consistent with what else we play and is easy to remember.

Is that standard or a specific agreement you have? It seems like many people would play that as an invitational splinter.

If you wanted to play 4♠ regardless of what partner has, you need to use Texas transfer. Jacoby transfer then 4M is an invite to slam exploration.

Surely I have a systemic bid to make here. I make whatever that bid is. For my answer to this poll, I assumed the same system I use when partner opens a precision 2♦ showing 4=4=1=5 less one card anywhere.

Some people play doubleton super-accepts. Why not transfer doubleton super-accepts? 2M+1 = club doubleton, 2M+2 = diamond doubleton, 2M+3 = oM doubleton. 3M-1 = Nothing to protect, I.e. Axxx Axx Axxx Ax and 3M = 4333.

If you don’t want to stop in 3♥, you should upgrade this to a 2♣ opening.

If you’re not playing Jacoby 2NT you’re not playing SAYC but a different variation of Standard American.

I overcalled 1N over 1C with a similar hand (spade honors were in clubs). The enemy kept leading hearts…

I bid 3♥ to cater to partner holding a hand like KQx, AKQxxx, x, AJx. If partner bids 3NT I’ll bid 4♦.

How does your partner bid 1NT over 2C?

4♣*

He did not do well to come in. A leaping michaels hand should be much stronger. With your hand, your side should get to slam after you balance with 4♦.

At this level I play the lead of a king promises the ace. Therefore I lead the queen.

Bid 1♠ first, then double hearts at whatever level it comes back at.

You should try to prevent, but if your partner isn't completely paying attention, I think there's room to let partner beer and when they forget to call it, you call it and steal it from them.

Gotcha. With that hand (KQxx, v, Axx, KJ10xxx) I would probably bid 3♠ instead of 4♥. I don't want to be in game opposite a minimum 1♠ bid (AJxx, xxx, xxxx, xx or the like).

If West has the king of clubs instead of diamonds, grand is even more laydown. You have 6 spade tricks, a heart ruff, 5 clubs, and a diamond. You only go down on a ruff of the opening lead, or if clubs are 0-6 either way, with the person with 0 clubs having 3 spades.

It's a matter of agreement what bids above 5♠ mean. I play that 5NT is 2 keycards and a void and that the 6-level is 1 or 3 keycards and a void. Whether that is my agreement or yours is, I would prefer to tell my partner what I have. Your partner took control with blackwood rather than cue bid and ask for coorperation. In this case, East decided that if West held the same high cards but 4=1=3=5 shape, he wanted to play 6♠. If East had the same info about West's hand but that he had 4=0=3=6 shape, wouldn't he decide to play 7♠?

On board 30, would partner's response of 5N to blackwood not show 2 key cards and a void? Then you can easily bid 7S.
