Subject: History Heuristic

Hi all!

I did some measurements on my move-ordering, and it seems that the positive
effect of the History Heuristic wears of with increasing search depth? Is this
observed by others as well or am I doing something awfully wrong here...


History Heuristic:

    int table[64][64];

    every time the 'best move' was found (either fail-high or all moves
    searched) I do:
           table[from][to]+=remaining_depth*remaining_depth

    The non-capture moves are sorted in History Heuristic order.

Cheers!

Renze
