I am not sure what is the "doublecount D==0" but my counting is very simple. I count each position that was deposed on the chessboard for evaluation. Even when for given ply existe 30 nodes (all were found) and 6 was deposed on the board before the response was found, 6 will be counted by speed counter. Leonid.
