I probably should have bid it more slowly, but I was playing quickly and didn't consider void responses. I was somewhat stumped over what I was supposed to bid over 5NT after deciding (arguably wrongly) I want to be in a grand opposite a club void and decided that lying about having the ♦A was my best option, as long as I denied the ♣A.
This hand also brought up another flaw with double dummy simulations. If West leads a club, how many people are taking an early heart finesse to pick up Jxxx?
