I also don't remember the exact score. One impression I had was that when it guessed correctly in pondering, then moved instantly, this was the move that would get it into trouble in several games. In retrospect, I'm not quite sure we had the program operating at full strength. I did not have any experience using W-Chess beforehand. I followed the directions I was given, but at that time Windows 95 was also only a few months old and I'm not sure we had the maximum hash tables. Also, the time settings I was told to use were very conservative, i.e. we set the program to think it had only 21 minutes for the 30 minute game, if I recall correctly. This was not really necessary as I was easily able to keep the programs clock within 1 minute of the game clock, and I think the program could have benefitted from the extra time had it known it had more time.
