I do count only positions for each ply that was searched my logic in one second. I don't count all the positions that existe for given ply. If, for instance in some ply existe 35 nodes, but only 6 was searched to find exact value for that ply, speed counter will add only number six. If you will count number of all nodes that your program find for each ply, speed counter will be wonderful. It can go up easely three time to the number of position that your logic is able to see in one second under the minimax. Leonid.
