I am annoyed about this hand. Playing BBO last night with a pick up partner in a team game, I picked up A 9873 AK52 7532 in 2nd seat, no one vul. After pass on my right, I decided to open 1D with the AAK, even with bad suits and spot cards.
Opps passed throughout, pard bid 1S, I bid 2C, pard bid 2H, and I raised to 3H, I thought patterning out. Pard bid 3S and I thought about bidding 4S, but finally decided to bid 3N, ending the auction. Then partner put down this truly amazing dummy on this auction. QJ7643 AK42 7 K9. That is right, he had an unbalanced hand with 4 Hearts???
3N was not a success on the Q of Diamonds lead and I eventually went down 4, double dummy guess I can hold it to 2 down, but I did not read the hand best. 4H was cold for at least 1 overtrick with everything favourable in it.
I asked partner why he did not bid 4H or ever show Hearts. His answer was that I could not hold 4 Hearts, even for the 3H bid, since I had shown 5-4 in the minors and then bid 3N. I had to be 1354. And it was somehow my fault for not getting to 4H.
I did not have any method of answering that, so I finished the next, thankfully last, hand and just left. I still do not know how his reasoning went on that hand. Hopefully I never will.
