I have no idea if it plays better in actual games. I don't remember what all the scores were, but I do remember WAC, which got 295/300 (and crafty without the Bruce Moreland extensions gets 293 on my machine). >>>>>>What did you change? Not sure what all I had to change. Here is the source code: ftp://cap.connx.com/pub/chess-engines/new-approach/C18_10.ZIP You can change the binary that is created by changing the macro as follows: #define DO_BM_EXTENSIONS does Bruce Moreland ideas #define DO_EXTENSIONS does the regular extension ideas Do not define both macros. If neither macro is defined, you get the regular crafty. >>>>>>How did you get SMP to work?
