So, Fritz5 would go down about 7+ ply on a fast system in 1 second and >Hiarcs7 would go down about 6 ply in 1 second.

So Hiarcs could in fact be searching deeper and have a lower NPS. My program's NPS has fallen from (if I remember correctly) around 600k/second to about 100k/second and the 100/k second plays _way_ better chess, bullet or otherwise. James
