Maximally pruned alpha beta tree

http://webdocs.cs.ualberta.ca/~hayward/355/asn/ab.pdf WebWhen the optimal child is selected at every opportunity, alpha-beta pruning causes all the rest of the children to be pruned away at every other level of the tree; only that one child is explored. This means that on average the tree can searched twice as deeply as before—a huge increase in searching performance.
