After all, it spots some motives in the position (winning material, weakening pawn structure, etc.) I'd say it could become pretty useful if it concentrated on the important issues. For example, "eliminating pressure on your King" is insignificant when you can just win a pawn. I guess you could extract similar information from other engines, too, if they printed more information about their evaluation function (not for all positions in the search tree, of course, but only for the PV). Maybe like this: PV is dxc6 Nh6 ... total score is +5.43 this score is calculated from: material balance: +3.0 white king safety: +0.15 black king safety: -0.2 mobility: +0.03 hope you get the idea... Crafty already has some debug options to print this kind of stuff. If you could enable it just for the PV it would be a useful start... >the player nothing about what has happened or will happen in the game. Relying >on that garbage would probably worsen your game. You must not expect too much. An engine can only search to a limited horizon, and has (usually) little ideas about long term strategies. --Peter
