Dave,
Thank you for Chezzz. It played very well against Crafty 19.03 SE (Petrosian
personality_ ten game - 5'/game match and provided for very entertaining chess
that I enjoyed watching very much. Although it lost the match, 8.5 - 1.5, that
does not diminish the hard work that you put into it and the excellent porgram
you developed.
I also like the opening book - although some lines were repeated the games were
not duplicated and the result was not always the same. The lines played were
very entertaining.
My favorite position of the match appeared in game 9 below.
[d] 8/5kpp/p3b3/r7/1p2P2P/2p2PP1/P1R2K2/2N5 b - - 0 48
49.... Bxa2! -- a double piece sacrifice to give the pawns the potential for
greatness!
Thanks,
Michael
