Has anybody beaten the new Chessmaster yet?
I just played a 10 min rated game to a draw. I had the white pieces. (French Exchange)

I was fortunate enough to get two wins against Chessmaster 10th. edition, and recieved certificates for doing so.
Are there also certificates for defeating Chessmaster 11? (hopefully, someday)

Yes, there are certificates in Chessmaster Grandmaster Edition...

I'm sure someone has beaten Chessmaster Grandmaster Edition; however, I haven't been able to yet.
