Like you guys, I'm really excited about CM10 coming out soon. I was playing a mock tournament in CM9k with a number of random computer opponents and was astonished at the following line: (Keep in mind that I haven't played CM9k in a LONG time, so I'd forgotten how absurd some of these sacrifices can be)
Me-Alicia(about 1335 I think, the lowest seed)
1. c4 e5 2. Nc3 Nf6 3. Nf3 Nc6 4. g3 Nb4 5. Bg2 Bg4 6. a3 O-O?? 7. axb4 Bxb4, and so on. I traded down, won a few pawns in the process, which is to be expected given her rating and won easily. My point is that a 1335 player would NEVER play 6...O-O. I mean, even a beginner would respond to the a2-a3 push, there's no discretion involved. I would only expect that sort of sacrifice(which isn't even a good one at all)from a 2000+ player down at my club in an effort to cramp me.
I have no idea what my rating is, it was 1475 a while back. I play on US Chess Live and maintain about an 1800 rating std there, but that means it could be anywhere from 1300-1600 USCF, it's a real grey area.
Anyways, my hope is that in CM10 we'll see a more realistic style of play from these lower-rated computer opponents. I'm teaching my friend how to play from scratch and have encouraged him to pre-order the game, so I hope that he can practice against the comps and gain good practical experience.
