I think that it is not fair from Enrique to do it. I guess that the multi versions of Rebel or Tiger earns less from more processors but still earn something from them because it is impossible to optimize programs for more than one processor in a short time. Am I right? Here is an idea how to use 8 processors in a simple way. Give one processor to analyze in the regular way(I will call it processor A). Guess 7 candidate moves to be the best move and give the other 7 processors to analyze only the candidate moves(one move per processor). If proccesor A do not suggest one of the 7 candidates move as best and if the score of the move of it is better than the scores of the other processors then play the move of processor A In the other cases play the move with the best score based on the scores of the 7 processors. If you can guess correctly in most of the cases then it means that you can search 1 ply deeper in most of the cases thanks to the 8 proccesors. Uri
