I have been wanting to improve by playing more live games. The issue is that I am a family man and OFTEN interrupted (haha) and so I feel bad about starting a game with a human and bailing. Also my rating plummets because I lose concentration for a sec and I am suddenly rated 900.
I've noticed that on the iPhone Chess.com app, you can play the computer and you can set its strength level from 1 to 10. (Weird that on this site, via a browser, you can only set it to "Easy", "Medium", and "Strong" and etc).
Well I "think" I have figured out the ratings of each of the 10 levels based on pitting the chess.com computer on level 7 with another chess engine where I was able to set the rating. The chess.com computer defeated the other engine set at 1800. So I think the chess.com computer's strongest level is 2600. (It COMPLETELY destroys me on level 7. My God I couldn't beat it in 100 games.)
So here is what I believe to be a close proximity to the chess.com iPhone computer strength level ratings. I was able to destroy level 2, and that strengthens my theory. (This was in a blitz game and I am not a very good blitz player, so I think the following is correct). If anyone actually bothers to read this and thinks different, then I'd love to know better. :)
