Apart from OS issues (not sharing ressources consistently or evenly) there is the problem of one of the programs not having a ponder move at some moment in the game. This can happen to many programs in case of fail highs or lows. In this case the other program doesn't only have the (fair) advantage of being able to search while the other one sleeps, but even worse it can think with doubled CPU powers now - as the normal 50-50 suddenly becomes a 100-0 . As fail lows and fail highs seem to happen more often in critical stages of the game it becomes even worse. Peter
