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

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 /

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.
