Anyone else notice this? I have noticed this too. I always figured that the reason the program castles on the Qside in the first place is because he is unable to do so on the Kside...... viz: the game is not going ideally for him and he is in a slightly weak spot. I'm just curious - assuming that a program can castle on either side on the same move, and assuming that all tactical and other strategic considerations evaluate the same for both moves, which side will the program choose to castle on? Is it a random choice between the two moves or is Kside castling preferred? What about other positions where 2 or more moves eveluate exactly the same (rare as that may be!) how does the modern chess playing program handle this? CC.
