For example, in my program a full ply of search is equal to 20. If I ran across a situation that I only extended by 10 or 15, then it would take another extension to push the depth variable "over the limit" to generate another ply of search. I haven't tested this exhaustively, but I started out extending *everything* by 15 (3/4 ply). After a while I just changed all my extensions to 20 (1 ply), which yielded better results on the tactical suite WAC. I should go back and spend some time testing, but haven't gotten around to it yet. -- James
