This is from a daylong tourney. In the 4 card ending when I tried to exit a club hoping to throw West in, it should be an open book seeing it is holding the 13th club and heart and North can't have the ace of diamonds. Yet it somehow messed this up. This ended up giving me 3 of the last 4 when I should have been losing them all.

Solid play all around. West avoided the endplay by ducking the ♣A, and GIB East did well to not be pseudo squeezed out of ♦A.

GIB just seems to play cards at random these days. The third 100% losing play (no matter the distribution, even if North did hold the diamond ace) that I've seen recently.
