This was the auction we had (4 card majors Acol style non forcing NT), I had a decision to make as to whether to bid 6. The knowledge I had was that partner had ♥Axx without the Q, and <4 spades, and probably 4 other points, maybe 5. I decided to bid 6 as Qxxxx, or QJxx in either minor will see me home even if there's a trump loser, Qxxx gives me a chance and trumps breaking and a 3-3 break will always do if nothing else works on any hand partner may hold.
How do you play this on a spade to the J-A (all follow to the first round of each suit without anythng that interesting happening).
