you open 1S, partner replies 1NT, what would you rebid (possibly wrong forum)?

Your partner has
x

KQxxx
Kxxx, what should he rebid? If you end up in spades you will be declarer and LHO will lead the ♣Q. How would you play?

I hope at least one of the three questions is interesting.

Matchpoints. All of the x's are very, very small and opps have no idea what signalling is.

Aunt Kathy and her sister would probably bid it 1♠ - 1NT; 3♠ - 3NT.

3♠ rebid is about as obvious as they come. If all decisions were this easy, I could win Bermuda Bowl on a good day.

Playing 4♠ after ♣Q, there is nothing to lose by trying to pitch a heart on the third diamond. Only question is whether to lay down ♠AK first.

Rebid 3 ♠. Your hand has 16 HCP, a reasonably good 6 card ♠ suit, and really no other suit to show. A jump rebid shows exactly that hand. Partner will know to pass with the 5 to bad 8 hand and bid on with a better hand.

Partner has a decision to make -- pass 3 ♠, bid 4 ♠, or bid 3 NT. Partner's problem is that there in no way to obtain more information about your hand. Holding a good 8, I think the choice for partner is between 3 NT or 4 ♠. With bad ♥ spots, I think 4 ♠ is better.

The opponents have helped you by leading ♣ Q. They didn't find a lead and cash 3 ♥ tricks.

Win in your hand with ♣ A.

Cash ♠ A. If neither ♠ Q or ♠ 10 show, cash ♠ K. If spades are 3-2 and the Q is doubleton, you can draw the last trump and pitch a losing ♥ on the ♦ Q making at least 5. If spades are 3-2 and the Q has not fallen, you still make 4 so long as the hand holding the ♠ Q also has a doubleton ♦. You next cash 3 rounds of ♦ and pitch a ♥ loser on the third ♦ winner. If the hand with the ♠ Q has exactly three diamonds, diamonds will break and you have a chance to make 5 by playing a 4th ♦ trick and pitching a 2nd ♥ loser.

If the ♠ Q falls when you cash the ♠ A, you can cash two more ♠s [K,J] and hope the player with the ♠ 10 fourth has at least 2 ♦, continue playing as above.

If ♠ are 4-1 and the ♠ 10 falls when you cash the ♠ A or spades are 4-1 and all low cards show when you cash the ♠ K, you may still have some possibilities via a trump coup.

Had the opponents cashed 3 ♥ tricks against 4 ♠, you would have been down to bringing in the ♠ suit without the loss of a trick at best. A 4th ♥ led from in front of your hand might well effect a trump promotion. In that case, your best hope would be to ruff with the ♠ 9 and hope ♠ Q10x were in front of your hand. Without a 4th ♥ return, your best hope is to cross to dummy and finesse the ♠ J hoping for 3-3 ♠s with the Q onside.

I would rebid 3♠, but I don't have the same glowing optimism of the other posters. I just can't justify bidding less. The hand has 6 losers by MLTC, which is less than is required for a strong rebid, but one of those losers is the ♠Q which may not be a loser opposite a moderate fit.

Depending on partner's hand, the 3♠ rebid will either work very well or very poorly. If we have a fit, it should work well. But we may have 3 quick losers and a lot of work to do in a spade contract.

My 3♠ call is going to give partner a major headache on the hand he holds. I hope that he guesses well. And, looking at both hands, I can't tell you whether I want to be in 3♠, 4♠ or 3NT (or, for that matter, 2♠)

rmnka, trumps were not 3-2 or 4-1, I'm confused (you do talk about 3-3 in your last paragraph).
