Oh well in wcc 99 at 3 minutes a move at a quad xeon from Bob, with 400mb hash in endgame i searched always 15 to 20 ply. However endgame of DIEP was real BAD then. Now after i improved endgame considerable, it suddenly searches a lot less there! i haven't figured out yet why it doesn't search that deep in endgame anymore. My focus obviously is not at depth, but at evaluation! That is, first get a few plies, then fix evaluation! At 5:43 AM here it's hard to calculate, taking into account bigger hashtables as i have now! First let's do a few experiments next few weeks with this 256mb RAM dual 800, then after that let's extrapolate it!
