'''Parity Pruning''', <br/>
an asymmetric consideration in various forward pruning decisions based on the [https://en.wikipedia.org/wiki/Parity_%28mathematics%29 parity] of the [[Ply|ply distance]] to the [[Root|root]]. The idea is to prune more aggressively on even plies when [[Side to move|side to move]] is the computer player, but less aggressively for the odd plies.
