You are missing the point, or you do not understand how thread priority works. The thread with a higher priority ALWAYS runs first. The lower priority threads will almost NEVER get any processing time. Add in the fact that there are 30 or 40 of those threads competing for the "almost never" cpu time they will get, and not a single one of those threads will produce one bit of useful information. Your higher priority thread will be searching normally, maybe 10-12 ply deep, and your other threads will be at 1 or 2 ply and will provide no useful information for you to determine if another move is better. >Note that I do not use threads in movei but I guess that I can change the >priority of a thread during the search. You can change the priority of threads, but there isn't any point. Just ponder one move normally, and if you see that the move you are pondering is bad, ponder a different move. The thread nonsense doesn't help you at all.
