I have CM9000 so I tried it. I have one question since I am learning how all this relates. My Pentium 4 2.66 got mate in 13 with the following stats 10:45 5/12 Mate13 202379725 My question is I have made no changes to CM9000 from a normal install and updated on the internet but it shows 202379725 positions while you have 124074955. I knew nothing about chess programs and how they work a few months ago, so I am trying to catch on quickly :) Richard
