First of all, if you want PM's log file for this game, just ask and I'll email it to you. It's too big to post here. The first interesting position is this one: [D]8/p4pk1/3p2p1/Pp2p3/1P1n2P1/6KP/4q3/2Q2R2 b - - fmvn 38; hmvc 3; id "PostModernist vs Chezzz, move 38"; sm Qc4 PM definitely wouldn't exchange Queens here, as it thinks this is a nice attack. PM's score went from -3.1 to -1.4 here. (Why not Qd3+, which PM was expecting?) Unfortunately in that score of -1.4, PM is underestimating the Chezzz's passers and the score drops again to -2.4 here: [D]8/p5k1/8/Pn1ppp2/1Pp5/5K1P/8/6R1 b - - fmvn 46; hmvc 1; id "PostModernist vs Chezzz, move 46"; sm Kf6 I don't think Kf6 is right in this position, although it looks like it ought to be right. What happens is that the h3 pawn starts to get dangerous, and it's hard for the King and Knight to keep control with threats on both sides of the board. With Kh7, although it looks counter-intuitive, I think that the four passers in the centre can overrun the King and Rook. My program gives the h3 pawn an "outside" bonus for being on the edge of the board, but it's *tiny*. If the King was on the c-file (maybe the d-file, I can't remember), the bonus would start to get bigger, because both Black's pieces are far away from the pawn. In this game, the situation is confused by the presence of the Rook on the g-file when the King is on the f-file, I think. Because of the Rook, the King might as well be on the c-file, as he can't ever interfere with the Pawn. Note that PM didn't have a positive score in the ending until after Ne6, although the mistake is much earlier, I believe. Andrew
