Opening lead A♦. Table result 5♣-1 0%
My partner was scathing about my choice of 5C here at the North London Club this week. But I thought he should have just bid 3NT on the first round. He said that I should double 4D, as he thought it was 1100 even at adverse. I think declarer can get out for 800, but bidding 5C looked normal to me. I suggested that we had 10 clubs and they probably had 9 diamonds so we were not likely to get rich from 4Dx. He said "They were playing in a Moysian at the 4-level, and you didn't double them. Give me a break!"
Who was right?
