In addition to the options of masters games and one persons games, how about adding an option for games played on chess.com?

It appears to me that in games below master lever, there are far fewer draws, and the results would be quite different.

I like your idea, but there is a serious catch to it. If you look at the rating distribution on this site, most players are in the 1500 range. Thus, results would be skewed according to how less accomplished players perform.

This is what I'd suggest: performance results sorted by player ratings. This would probably be implemented as options in the drop down box--beginners, intermediates, masters, grandmasters, world champions (or only the first three if you don't want to mesh databases).

Another option could be a sort based upon your average opponent. I notice this is something you already have in your database.

I'm not sure how the chess.com game database is set up, so this may be more complicated than I think. Player performance results would have to be iterated through and compiled yearly (at the very least). A lot of people are inactive, so you could optimize the process by looking at log-in frequency and skipping over the ones who almost never play a game.

I'm assuming a distinction between tournament, live, or standard games is out of the question.

Plus, there would have to be separation between blitz, bullet, and long. But I like the average opponent rating idea, or maybe a game database between players with a rating just slightly higher than you to help you improve.

I just got an idea--I hope I'm not getting off topic.

There's something I've always wanted, and one can't find it anywhere: an opening knowledge quizzer. You'd be shown a position, say ten moves into a game, and it would be your job to identify the opening. Multiple choice.

It would be a very big project--we'd have to come up with our own rating system, since this is something never-been-done.

EminenceGrise's point about skewing the numbers toward weaker players make a lot of sense. I still think it would be nice to have an option of seeing results from chess.com players (perhaps by rating ranges as EG suggests, or as simple as 3: under 1500, 1500-1999 and 2000+).

Separately, I like his idea of an opening quiz also.
