smerriman Posted February 27, 2023 Report Share Posted February 27, 2023 :( West's double shows 21+ HCP in GIB's system, so it's another classic example of ignoring the fact there's trivial 100% lines in favor of reading too much into the bidding.

So West doubles showing 21+ HCP and East's 3 level intervention is suddenly -2 HCP?Surely ruffing hearts at trick 7 cannot cost, even if W has KT9x?

GIB just doesn't know finessing in hearts can cost. 21 HCP is obviously impossible but it still takes it into account when simulating, and all hands where East had the king were too far away from what it was trying to simulate to be considered.. Age-old bug with some easy alternatives, but nothing was ever implemented. Quote Link to comment Share on other sites More sharing options...
johnu Posted March 1, 2023 Report Share Posted March 1, 2023 Good try by GIB. On another layout, the finesse would have worked. Are you expecting GIB to play double dummy? :) 1 Quote Link to comment Share on other sites More sharing options...
