Not exactly, Dan. The nps stays unchanged, but Tiger does more agressive
pruning, so it manages to get at the same depth significantly faster. That means
generally finding the right move faster, and sometimes being able to go 1 ply
deeper in the same time.

The risk involved (overlooking a good move deep in the tree) is far overweighted
by the significant "speed" improvement (but we are not speaking about nps here).
