cencio Posted March 13, 2019 Report Share Posted March 13, 2019 [hv=pc=n&s=stha942dkj72ct976&w=sk865ht7653dat4c8&n=sj42hqj8d53cakj32&e=saq973hkdq986cq54&d=e&v=0&b=14&a=1sp3sppp]399|300[/hv] In this hand, after starting with ten♣, take by N with a♣. Nord, if it is a gib robot, return in a different way based on contract, once 3♦ or 5♦ if the contract is 3 or 4 spade Quote Link to comment Share on other sites More sharing options...
BillPatch Posted March 13, 2019 Report Share Posted March 13, 2019 I imagine that GIB sees that the honest count lead has a reasonable probability of setting 4 ♠ , but false cards, against 3 ♠, either because it might produce an extra trick to set 3 ♠/ Quote Link to comment Share on other sites More sharing options...
smerriman Posted March 14, 2019 Report Share Posted March 14, 2019 GIB has no concept of falsecards. Why it occasionally breaks rules to lead a card when simulations could not possibly tell it so, nobody has any idea. See more examples here, like the leading from a doubleton section - it's clearly programmed to follow a rule but then breaks it on rare occasions for no reason. Asked jdonn a few times but he never replied. Quote Link to comment Share on other sites More sharing options...
