Unfortunately, I have to disagree. As I remember it, immediately after the sac, Fritz scored itself as being positive. Then, after a few moves, its eval went down to 0, and stayed there for quite a while (Crafty was still scoring itself as quite positive - between 1 and 2 points). Eventually, of course, it came back up again and Fritz won the game. By the way, I will try to obtain Crafty's logs for tomorrow. The time setting was 60/115/sd/25 - which means 60 moves in 115 minutes followed by game in 25 minutes (the actual clock time was 60 moves in 2 hours and then complete the game in 30 minutes). -g >Greetings >Alex
