If you log the commands passed from the winboard adapter to the engine you find that, for every move, they use a scheme like this: new force e2e4 e7e5 [rest of move list] go they use this trick also to emulate pondering in engines that actually don't support it, the CB/Fritz interface simply choose a candidate and send the same sequence as above during opponent time, so the engine thinks that it's already it's turn and starts the search; when the user moves the CB/Fritz interface moves immediatly if the prediction was right... My engine, for example, does not tollerate this behaviour very well, since it starts to generate illegal moves near the end of a game (probably some "result/mate" flag gets screwed up) Regards Luca
