Tweaking the futility pruning formula Huge credit goes also to candirufish, as the idea was first tried by him, and then tuned by me at multiple phases. Tweaking the futility pruning formula to be a bit more selective about when pruning is applied. Adjust the value added to the static eval based on the bestValue relative to ss->staticEval. If bestValue is significantly lower, we add a larger value.
