No, but it does retain the hash-tables. My problem with it is that if i go back
a move it will play it instantly without clearing the hash-tables. Ex: I submit
a position for it to ponder. It produces the move. Fine, now suppose I wanted to
time it properly. If I let it play it's planned move (which it took 5 minutes to
choose) and then go back and ask it to think again, the move will appear
immediately as it's prime candidate. In order to clear the hash tables I have to
have it compute a different position and then come back.
