Justin was assuming imps, so 120 vs 140 or 90 vs 140 are only 1 or 2 imps compared to 4 to 6 when one makes and the other is down, and 2 or 3 (or rarely 4) imps when they're both down but different amounts.


Aaah. Thank you. Now it makes total sense. I always assume matchpoints. In fact, I likely think matchpoints even if something said IMPs.

In matchpoints, imo, 1NT semi forcing has a definite advantage of playing 1NT and not minor

"But I don't want to go among mad people," Alice remarked.
"Oh, you can't help that," said the Cat: "we're all mad here. I'm mad. You're mad."
"How do you know I'm mad?" said Alice.
"You must be," said the Cat, "or you wouldn't have come here."

That wasn't the debate.

And as in my favorite partnership, we don't even play 1NT SF, I don't think that I'm the one needing convincing.

In a 2/1 GF context where 1NT response to 1M can include :
1. 3 card support in M , Invite.
2. 3 card support in M , "mini-raise" (4-5 points) - though this is rare, raise on some of those.
3. Invitational hands with a minor suit , but not with . (1 - 3 is nat , inv).
4. 10-11 "balanced" , or with short M , but never a GF hand.
5. All other "normal" 1NT response hands...

Do you think it is a good agreement that opener can Pass 1NT with 5332 11-13 , or similar?


There are some pairs that include a 6th option .. a flat 12-14 points with 3 card support. Of course this requires that 1NT is 100% forcing. But if it is, it's nice to not have to bid 2 with AQx Kxxx Kx Jxxx. Instead you bid 1NT followed by 4M.
If no one comes from the future to stop you from doing it then how bad a decision could it really be?

There are more options than that if 1NT is forcing, but your general idea is one of them ---with variations in our style to allow 1NT-then 3NT to show the flat 13-15 with 3-card support (choice of games) and 1N-then 4M for a hand too strong for a direct 4S preempt but having 5 of them.

I think playing 1N opposite a balanced 3 card limit raise will be a massive winner over playing 3S. Spades is supposed to take THREE more tricks? Yeah right. I think it is opposite an unbalanced 3 card limit raise where 1N and 3M might break even. (All of that was assuming imps).


Good analysis ! It is the first time I find a very good justification of the "semi"forcing 1NT: responder did bid 1NT on 3=4=3=3, and opener passes on 5=(2-3-3).

This was valid after a 1 opener. Same goes for the the 1opener.

On 1 the 1NT could hide a flat support hand. : 2=3-4-4, or 3=3-3-4 and opener passes on 2=5-3-3 or 3=5-3-2 (12-13HPC).

On the other hand very often (I would say expert practise) a single Major raise is often played as moderatelyconstructive,and the 1NTbid can hide a weak 3card suport. In that case 1NT might not be such a good contract.....But then I guess the opps have something to play.....strange we have not yet heard from them...:)
