TweetMan, I had it and I left my rook unprotected and totally lost my set up to take the king, then slowly but surely it took me down. I took 7 pieces before it took me. At the end, lol, I was dancing all over with my king and I hd the perfect set up on it's king but I could never make a move without it being able to have a move on my king and then eventually, I got cornered. I didn't want to move my queen or bishop out of place because they had the king set up. LOL
I have Chessmaster 10 and it's tough too. You rarely beat the computer but it teaches you opens and attacks and defenses, it's pretty cool.
