Doesn't this go against the definition of >>MVVLVA? The idea is that captures by the King always win the piece, because the King can't move into check. Captures by other pieces may result in the capturing piece being recaptured. This might be complicated by the way you detect King moves into check. >> >I just ran some quick tests. For my program following MVVLVA rather than MVVLVA >(but sorting these king captures first) seems to be about 5% faster. Anyone else >tried this? I tested it ages ago, can't remember how, but putting the King captures first seemed to help. What tests did you do?
