EDIT: The hand has changed. this is the right one in the club. Too tired...
Sorry! The bidding should be the same of course. I truly remember i have bid ♦ 3 times.
Playing pairs,
It was 22:25pm , nearly the close of the club. We were still running the last board.
Feeling too tired, and respectful of my partner's bid,
I let 7♦ go.
Both 7♦ and 7♥ makes but we went home without seeing the IMP.
Do you think we had the top ranking for this board?
E-W Hands
Lead on my table: ♠A i ruffed it by ♦5 (should be ♦A) from dummy without blanking an eye, leading to my memory confusion.
