Because you won't be playing with ponder=off in "real" >games, just like the rest of us.. I believe that testing with ponder=off is going to help christophe in "real" games. You can learn much from the games about positional problems. You can also see some problems in time using. Every case when you play with ponder=off is similiar to playing with ponder=on when the opponent is using 0 seconds for his move and it happans often in comp-comp games when the opponent expect your move. If your opponent is deep blue chip and it is using 0.1 seconds per move(in ICC) then you have practically almost the same situation as playing with pb=off It can be practical when deep blue chip is going to be commercial in ICC and someone is going to test it in ICC and give it less time to give the opponent chances.
