We had our worst boards against the pair who went on to win North/South. I'm not sure which direction the causality runs -- do we tend to play badly against pairs who are in fine form, or does the pair we don't get good boards against tend to win?
See if you can spot the misdefense on this board against the pair who would go on to win in the North/South direction. We were sitting East/West, and after partner opens a weak NT, I know that we have the majority of the points. On principle, we do not let them play a 2-level contract undoubled. Also, partner will not bid again unless he has a 5-card suit. So, the final contract was 2C doubled. We had two chances to set them, and we muffed both chances. Can you do better?
I was sitting West, so click on West to hide the other hands and then click "Next":
-180 was a bottom, of course. +100 would have been a top.
