I have another idea. May be it's better to sort (by nodecount) independently two
groups of moves: the moves that was best moves in previous iterations and moves
that was not. The first group of moves must be searched first. And also may be
it's good idea to add some "expire" function that will decide that move from
group 1 now can be transfered to group 2. The easy way is to expire moves which
was best for early iterations (root_depth-4, for example).

>i need your results to compare :-)

I'm experimenting on it :) I will publish my results.
