Some of the speed-critical functions are now in assembler, if it's compiled with MSVC. The rest is in C (The TB probe code is C++). >Just can't retain me to not mention what really puzzled me in the game. It was >one idea that never went away.

But maybe I rush to the conclusion. I don't know of any chess program written totally in assembler (Except perhaps Fritz). I think most everyone uses C/C++, because it is fast, powerful, and not too difficult. It is quite difficult to write an entire program in assembler, however, because once it's written, it's very difficult to modify the program very much. Programs like Crafty are being modified almost every day, to make them better - doing this in assembler would be a major headache, IMO. In addition, Bob releases his source so others can see and learn from it. Since C is much easier to read than assembler, it seems illogical to do it completely in assembler. Nobody could read it if it were totally assembler. :) This of course doesn't apply to the commercial programs, but they still don't use totally assembler, I think. Jeremiah
