Gib appears to have no memory.

Here is a hand where it had to play KJT opposite xxx.

If first finessed for the queen and then when it repeated the attack on this suit it played the king rather than repeating the finesse against the queen.

This happened in a robot tournament and 19 times GIB declared 4♥ for 19 failures. All of the several failures I have looked at were through this identical inferior play.

Scoring: IMP

That's because GIBs doesn't use a play plan- it simulates the total hand for each play and obviously simulates it separately so after successfully finessing it has no memory of the actual play rather it considers it more likely that the RHO has a queen of spades and therefore has to a singleton at that point for hand to be made.

This has nothing to do with memory. I am sure GIB too plays with some plan (however bad that might be ).

GIB's play is nothing unusual for a computer without nerves. After all how does he know if rho has ducked holding the spade queen? He simply misguessed and went down.But there was a better way of playing the hand.
