I realize that big programs require big computers. That is clear. But if all the chess engines were to be tested on the same computers, you would have thought that all of the chess engine developers would have optimized their programs for the computers they were to run on. This includes "paring down" a big program if it will have to run on a "small" computer. That's what got me to thinking, anyway. I couldn't understand how Hiarcs 8 had been zapped. For whatever that's worth. Bob D. Bob D.
