Hello! >I see king knight in the same group. >pawn bishop in the same group >I understand that the logic is that moves of this pieces that are not captures >by pawns have to be different and captures by pawns are not relevant because >they are always considered as good captures(there are cases when they are bad >and it may be better to escape with the queen if the opponent threats it but >Crafty does not generate escapes first) Yes, you're right. Threats detection also can be used to improve move-ordering. If threat is capture we must try (with larger priority): moving piece away (with SEE>=0) and protecting piece (if threating piece is more or equal valuable as threaten). Also we must try some checks before other moves. I'm experimenting with it. Best wishes, Sergei
