You don't need to understand my logic. Just play the move of the game at 8mb
hash, you will see what I mean. Rebel at certain hash sizes plays like a
different program with big eval changes when set on 8 mb hash for Rebel 10
playing with 10 mb hash. Very strange,,,but check it out you will see.

example, when rebel 10 set on 8 mb hash at move 19 will play Bxg7 in a few
seconds and stick with it. If I set the hash to 10mb it takes Rebel 10 over 6
mins to see that Bxg7 is better then Nxb5.

 Are you saying by lowering my hash table
