Apart from simply just playing, you'll also receive useful feedback, for example: There is also a Chess Mini app, that plays interesting chess at around FIDE 1800 to 1900. You'll also find my own chess engine in the SmallChess app. You'll find a Stockfish app with adjustable playing strength. Please visit my site to try my chess apps: Please note CCRL rating is not directly related to the human FIDE rating, but it's a reasonable estimate in any case. gives you a huge list of engines with their CCRL rating. I merely would like to vaguely know the general level of my computer opponent while I play.Īt any rate, any recommendations for a free online chess engine with adjustable difficulty levels, whose elo ratings are roughly known? I am not demanding a highly specific rating. Lastly, I am aware that Elo ratings for chess engines are a fuzzy subject - given that they don't make the same kinds of blunders that real humans do, don't give up, play at different levels in different situations, etc.

I realize that most purchasable standard chess software has adjustable ratings, but I don't feel like buying any right now.

Thus, Chess Titans doesn't fit the bill of being able to beat me somewhat more often. I can readily beat Microsoft's Chess Titans at all levels, including level 10 (or I should say I can beat it at least 3 out of 4 times). Of course I'd rather play OTB (the best practice) but life/job/family commitments don't allow for too much of that these days.

To clarify, someone once recommended that when playing alone against the computer, I should find a difficulty setting that I can beat roughly 2/3 of the time, and another that I can beat only about 1/4 of the time. In short, I am looking for an online free chess engine that has either:Ī.) multiple engines with multiple ratings, some as low as 1500-1600, and some as high as 2200 or better,ī.) is a single engine with adjustable difficulty ratings from about 1500-1600 and up.
