If ponder is off then it uses only 50% when it is to move. If the match is ponder off then each engine only uses 50% on it's turn to move. If a dual is used it will use 100% on it's move and then on the opponents move the opponent will use 50%\ In my case right now I have two chessbase interfaces open Chessprogram7 and Chessprogram8. Each is running engine matches with each match having 50% CPU and each engine with ponder off. You can check simply in task manager and see engines switching. You can also assign CPU1 and CPU2 to a specific target lets say CPU1 to ChessProgram7 and CPU2 to chessProgram8. Sarah.
