I know cm9k is old,but thats what i`m useing.
Are there any chess pieces for cm9k i can down load?

No, there are no extra sets for Chessmaster 9000. If you want extra sets, you'll have to upgrade... there are several additional sets available for Chessmaster 10th Edition.

Actually there were two additional chess set for Chessmaster 9000, but they aren't available anymore. I used to have them, but they are lost now.
