I >don't >think it did in that game... In Hossa's first serious tournament game against Nimzo (CCT1) I had a similar bug. Hossa made two "random" moves (or better two one ply moves) because of a bug in my permanent brain code. The first move wasn't that bad but the 2nd ruined a won position. 1st 1-ply move: [D]6k1/p4ppp/4p3/3p4/3PnB2/2PqP3/P5PP/1R2R2K b - - 0 22 22... g5 [D] 6R1/7p/4ppk1/p2p4/3P1B1p/2n1P3/q5PK/1R6 b - - 0 31 31... Kf7?? (31... Kf5 32. Rf1 Ke4) In both cases I thought "this is ridiculous". But you are right, the quality of a move doesn't depend on the fact if it was calculated by a deep search of fantastillions nodes or by an ape who made the move randomly. Greetings, Steffen.
