Solution of WAC #141 was slow for me. It took 700+ seconds on a Pentium 133mhz. The pawn tranposition table hashed 98% of the scores. I know there's been some discussion about #141 before. What kinds of improvements help solve this problem? I'm hesitant to go making a lot of changes for one problem unless someone says they've helped in other areas and are willing to describe them. --Stuart
