At least Moro seems to suggest he missed it over the board. It is "strange" because you look at the attack and the move has a meaning only after the inbetween check Qc5,. >The logical moves are checks or captures or threatening white's pieces A check is not a "logical move" in this case it helps to build the defense, but to often patzers play checks just to shift the end by one tempo. Not a big help. Also many non professional programs suffer from this: allow them few extra checks and they will hit the horizon. >Remember when you analyze always to look for these ideas and not only in the >first move: >In the first move there are 3 checks Qc5+,Qb6+,Qa7+(I ignore the analysis of >these lines in this post).... You're not talking a bout a computer! The selection of candidate moves down in the tree for a human is something harder. We don't work like a program (or like Kotov would like) we need to reject some lines and our way of going by patterns easily tends to suppress (mistakenly) a line which "needs" h5 in a position where out king is under attack and already weakened. That's part of the beauty of chess after all! ciao Franz
