I think that the result is not a good test because there can be different
definitions of nodes
It is easy by generating illegal moves to generate more nodes.

I think it is more interesting to know how much time you need to generate all
the legal moves and not to repeat the same moves but to generate a tree of all
the possible legal games of 3 moves of both sides.
