    Could you estimate a player's rating by going through some of their games? If so, how many games would it take to get a good idea?

    I ask some stupid questions when I'm drunk don't I?

    I don't know, are you drunk or sober?

    Stop using drunk as an excuse for why your questions are dumb

    I'll be getting drunk at the weekend.

    I'll come back on then and answer your question.

    chess is ultimately a game of who makes the fewest "blunders" -- the better your rating, the more subtle your typical blunders will be -- a blunder being a move that ultimately leads to a permanent loss of material -- or overlooking the chance to gain material -- and of course, moves that lead to being mated.

    so - one could go through each game, see where material was lost, a pawn passed, or a mate happened, and then find out how it happened and how it could've been prevented --- and then judge how obvious or subtle the blunder was -- obviously, it would be harder to find the "missed opportunity" blunders.

    there are probably computer programs that could do this and give a rather good estimate -- and I would guess you'd need at least 20-30 games to offset the occasional "DOH!!" moments that we all have.

    I'd go for about 5 games against similarly rated opposition, which kind of gives the answer.

    When a new guy comes to your chess club, you try to get him to play against a few different people, of different abilities, and go from there.
