It's impossible to do in my program-- I count the moves based on their score--
hash moves lose that information since their score is set to the highest
possible.

The order for the numbers I posted are (and this is based on Rebel's scheeme):

127 Hash
126 Mate killer (this is not implemented yet)
111-119 for winning captures based on material gain (e.g., 110+x)
63   killers
20   even captures
-20+x losing captures

The rest of the moves are distributed based on the piece table values (except
for pawn promtions and castling)
