At 200 KNPS (I do not know how fast Hiarcs searches, but this may be a fair guess on a fast system), this equates to about 96 seconds. This would leave about 84 seconds for selective searches per move in a 40/2 game. Of course, I am not using traditional Alpha Beta in my program and I do not own Hiarcs (i.e. I do not know their definition of depth 9/30), so I could be talking out of my hat here. KarinsDad :)
