MBC pickup partner. I was North.
we agreed to play 0314 RKC
now this hand comes up
The bidding went like this
W N E S
- 2NT P 3
♣
P 3
♥ P 4NT
P 5
♣ P 5
♥
P P P
The lead was the singleton
♠6, I played the
♠Q to force out RHO's
♠K and took all 13 tricks.
p asked me why my response was 0-3 (5
♣). I said
♥K,
♣A and
♠A makes 3 keys. He asked me why I passed 5
♥, and said he was asking for 7NT. I was dumbstruck.
Your opinion here plz...
Anything (bridge-related) is tolerated in this forum.
I think it is fair to say that the blame is joint.
a) A lot of people would not play 4NT in sequence as Blackwood, but as invitational (probably with 4 spades on the side, hence the 3C bid). However you were both happy it was asking for aces, so that's not a sepcific problem here.

You were North. You were looking at 3 key cards and the queen of trumps. If you had had two key cards and the queen of hearts you would have had to respond 5S to RKCB, which would have committed your side to slam. As it was, you have one keycard more than that. If partner was prepared to play a slam opposite two keycards and the trump Q, he must be prepared to play a slam opposite 3 keycards and the trump Q. So with a bit of imagination you can see that you shouldn't pass 5H.
c) I don't know what the point of the 5H bid was. When in doubt, never make a bid intended as forcing that sounds as if it could be non-forcing. But anyway, if he wants to make a grand slam try then one of 5D (asking for the HQ) or some higher level bid (random grand try) would make more sense. So while I sympathise with your partner that he should not have expected you pass 5H, he was guilty of confusing matters.
I confess, playing with a pickup partner I would respond 6NT to 2NT. It prevents this sort of accident.
