Well I must have some sort of problem, I haven't counted the nodes, but the tree
explodes for sure.
Maybe it is just move ordering, I haven't really adressed that issue yet, just
using MVV-LVA, probably not good enough.

I have basicly just copied Bruce's algrithm, I don't know what could be wrong.
It is playing okay (considering the depths it reaches), so I'm not sure there is
a bug.
