New mac chess is more difficult
I am running mac chess on Big sur and I cannot beat it at any level!
I also run an older version on a PowerBook which I can beat sometimes at 2 moves ahead and always at one move ahead but no chance on the Big Sur version. Is there any way I can reinstall an older version of chess onto the iMac so at least I can give myself a fighting chance? My backups do not go back far enough to help.
