In solving WAC at 5 seconds per position on a 950 MHz AMD Athlon machine, Crafty
solves 294 out of 300. That is pretty run of the mill as far as top engines go.
What is really interesting is how quickly the remaining unsolved 6 problems are
solved. I would be amazed if any engine can match it on like hardware.
