Increasing this parameter means that rebel needs more time to evaluate every position. So the time needed to complete a ply should in theory go up a lot, unless there would be very unexpected side-effects that somehow Rebel can find refuting lines quicker now and the search would become more efficient that way or something like that. I never really tried it but I know other people did. But in theory time to complete a ply should increase and for tournament games this is not compensated enough by the better understanding because of extra knowledge. But especially for analysis the exact time needed is not so important so there it is worth a try I think. But we do not know much from Ed in which kind of positions this extra 'Chess Knowledge' can be used. Eelco
