    Hi! I am playing two correspondance games (USCF)  against a 1300 rated opponent, and they are my first ones. I'm winning them both by a large majority, so I'm wondering what rating range my rating will be in after the games. I tried calculators but they dont work too well since they need an already established rating. Anyone know what my rating will be if i win both games against a 1300 opponent?

    The Elo system doesn't work if you don't already have a rating already, and can change differently according to what constant you use for determining by how much a rating will change. Assuming USCF rules and that your rating is by default 1200 (I don't know if this is the value, or if a system like this is used at all), your rating would be 1220. That's just how the math works.

    Check under "details" and it will tell you exactly how many points you will gain/lose in case you win, lose or draw. Check on the Chat, Note,Details.. screen.

    In the future, you can just go to the USCF website and visit their online rating calculator. 


    Enter the ratings of your opponents, your score, and the fact that you've played zero previously rated games.  In this case you would enter 1300 (twice), 2 for your score, (since you expect to win both games), and 0 for the number of previously played games.

    The calculator shows your performance rating, and your initial rating, will be about 1700, so you were spot on. 

    Note that the calculator approximates the USCF formulas, but I've found it's pretty darn close.

    @Pwn-Attak please don't be rude, just explain why he is wrong.

    @Boheme the default rating in organizations like the USCF or FIDE is not 1200, its unrated, and as with all elo systems, the first few games award or deduct more points. It takes around 25 games according to the USCF to get your real rating

    the default rating for an unrated player is 1200 when calculating your rating to start. what you do is you take the first person you play, say a 1300, and look at your result. If you win your rating is their rating plus 400, draw then you get their rating, and if you lose then you get their rating - 400. for your first few games you do this and average the ratings you get. then after some number of games it will change to the +- 32 scale based on rating difference as oppossed to base rating. your rating should be right about +400 of their average rating, or 1700 it seems

    I've never heard of any default rating in USCF or ELO ratings.  They figure a performance rating from your first four or more games with opponents who have established ratings.  This becomes your first provisional rating. 

    I believe it remains provisional for the first 20 games, then is established and future calculations are made on that.

    They won't publish a provisional until you have at least four games with different opponents.

    how much does a USCF membership cost.

  • 3 years ago · Quote · #14


    $46. . . which gets you the Chess magazine.

    Often you can get a special 1 year membership, with magazine, if you pay via Continental Chess while entering one of their tournaments. 

    For example, if you enter this weekend's Pacific Coast Open, in Agoura Hills California, the USCF yearly membership fee with magazine is just $30.00.  (If you pay online, with your entry fee, according to their ads.)

    Also, the USCF has discounts if you pay for more than one year in advance.  Last year I paid $113.00, for a 3-year renewal.  (I'm now paid up through the year 2021!)

    It's usually $13 or so cheaper without the paper magazine - you can still read the whole thing online.  Also discounts on 2 and 3 year renewals.

    I've lapsed again, because I haven't played OTB in a couple of years.  The magazine is pretty crappy, so the only reason I join is because I have to to play.  And that goes for probably half the active membership at any given time, if not more.

    Yea, I agree... the magazine isn't great, but I figure it's only about $2.00 an issue.  And for that price, delivered to my door each month, I'll take it.

    (Math:  $113 for 3-year membership = $37.66 per year.  I figure the yearly membership fee is "worth" about $13.66 per year and that leaves twelve issues of Chess Life at $2.00 each to make up the remaining $24.00.)

    And I'm still old-school... I much prefer a paper magazine, that I can hold in my hand and take to the beach or something, over something I read on a computer screen.

    I'm with Mr. Ed.  Just got my magazine 2 days ago for the first time, since I'd joined recently for my first OTB tourny, and there was an article on the bishop sac leading toward mate.  I'd wanted to find this for some time and voila! - there it was.

    I agree I prefer to read a book or mag while eating breakfast or something.
