For those cases you can avoid the complete SEE. It also helps to do SEE pruning analysis just before the capture is being played. Thus no SEE for all captures. If you already have all pseudo attacks available the actual SEE isn't that costly in my opinion. The cost is in fetching all attackers/defenders. And you basically have those, if you have the pseudoattacks ready. Regards, Bas Hamstra. > >>Personally I doubt it is worth the effort of perfect SEE sorting, but skipping >>losers is a win.
