Hello Kurt... You are correct in your analysis, partially. The one thing I am doing poorly at the moment is that Crafty tries to avoid pawn structures that are drawish, period, even if it has an inferior position. I have this on my list of things to fix. This came from the "draw masters" on ICC, and I really tailored it toward just going for open positions period, which is not a bad idea against humans. But against computers, you can't get yourself into too big a bind trying avoid a draw, or you succeed. You avoid the draw and lose. :) I'm still working, and every game will be looked at carefully to see what can be learned for next time. Thanks for the kind words of course..
