Analysis to reach a definitive determination of the best move is quite involved. I have sometimes taken many hours [48+] using Fritz to satisfy myself that a certain GM move [in a GM game I'm looking at] was best. There are many tricks to get the most out of the chess engine in this situation. When chess computers become ten or 100 times as fast, then this process will become much more popular. One must ask whether or not it is really worth the trouble. For an amateur like me, the answer is probably no. For a correspondence game between very strong masters, where the use of the computer has been agreed upon, then maybe. Analysis of GM games is an application where very thorough analysis may make sense if the analyst wishes to really understand the games. Just my two cents worth. Bob D.
