That would something like this (actually futility pruning): if(alpha>material_balance+mat_gain()+something) prune; We would be pruning if can't most likely raise the score above alpha. Alpha tells us nothing about present node when entering the node. So comparing alpha to -INF or INF gives no useful info. It just tells how the search is doing now. Severi
