Here is the hand:
Scoring is imps.
Two questions:
What calls mean what?
What to do?
A couple of stipulations:
A. I regard the 2S call as forcing, pass is not an option. Reject this if you like.
B. We are not playing Flannery, partner can reasonably expect that I do not have four spades.
C. The uncontested auction 1H-3D would have been Bergen. I mention this because with some people I play that with this shape but more strength it could go 1H-3D to show a good diamond hand that is not quite good enough for a game forcing 1H-2D. This, if we are to consider 1H-1NT-2S-3D we must allow for the possibility that if I had the stronger diamond hand the auction would still have begun 1H-1NT-2S.
D. We were playing constructive raises, so I assume that a bid now of 3H would be six points or so and three hearts.
We have not discussed if Lebensohl applies in this auction.
Now here is what I did.
1H-1NT-2S-2NT
I figured that if partner bid 3C, presumably thinking this was Leb, I would bid 3D and hope for the best. If partner passed 2NT, that might well be fine. Neither 3D nor 2NT looks great, but it seemed the best that I could hope for. Unfortunately, partner bid 3NT. Perfect defense holds me to six tricks, on the defense I got I could have made eight tricks, I actually made seven tricks.
I would not have bid my partner's hand as he had, but that's not my point and I won't distract from my purpose by showing it. I am thinking that my hand is not all that rare, so what do people do when they hold something like this and the auction begins 1H-1NT-2S?
