I would be interested to know how you check for mirror / rotation in the 
transposition table. Do you use Huima's hash function (which is broken)?
Another similar function? Do you store whole board position in the TT?
Do you maintain many hash value for the same board position (one for
every possible mirroring/rotation)? Or something else?
