I think there is a difference to CM. For Genius and Shredder, the formula is MaxDepth = Brute Force Depth + Selective Depth Therefore, if you set Shredder's selectivity to "12" and it is currently searching ply 9, it will not look at any line deeper than 21=9+12 ply. The same is not true for Chessmaster. Even with SS=0, when at ply 6, it is looking deeper than 6=6+0 ply as you can see by its search display. I rather believe that the SS setting is some more abstract number, like "don't use this extension if SS less than 7" or "follow capture extensions to at least SS/2+5 ply" or something... --- Shep
