Of course it was also significantly faster, by a factor of almost 7. Today that's no longer true. At the last WCCC we saw speeds beyond 20M nodes per second, which would most likely make Crafty stronger, since Crafty's search and eval are a little more mature that CB's... Also CB was not nearly so aggressive with null-move. We might have an older version of CB available (in Fortran) in a few months. I had an old printout (somewhere around 1989 or so) that someone is scanning at the moment, and will try to filter through an OCR program to get an ASCII source file. I can't find a printout of a version in the 1992-1994 period (yet) which means no singular extensions or other more recent things we tried. But at least we might have something everyone can look at. I also found a printout of blitz 6.9, which I believe dates back to the ACM event in 1978 (this was my first cut at a full-width program so it is pretty crude by today's standards). More as things develop...
