On your fast PC the engines all seem to run at the same speed, but on my PC you can tell who is really the fastest. List 5.04: 10 seconds (List needs 2 seconds to find mate on your PC) Chess Tiger 14: 3 seconds (0 on your PC) Shredder 7.04: 2 seconds (0 on your PC) Fritz 5.32: 1 second (0 on your PC)
