孩子5岁零7个月，昨天第一次获得Rating，409分。其他家长都恭喜我说很好，我们也很高兴，就是不知道这个Rating 是啥意思？
求科普

Ratings Explained

What is a good rating?

A rating is a number which indicates, based on your past performance, how good you are at chess. The higher the number the better you are.As at May 2012 the highest rated player in the world was Magnus Carlsen with a rating of 2835.
The highest rating ever was Garry Kasparov reaching 2849 in July 2000.

The best players in the world have ratings as follows:

World Champion 2800
GrandMaster 2500
International Master 2400
National Master  2300

For juniors in Australia (ranked #32nd best chess-playing country in the world at the last Olympiad) the easy way to gauge if you are on track to becoming a Champion is to take your age and multiply by 100.

Eg. Age 9, good target to have a rating in the 900’s

Age x 100  = You should be playing in State Championships
Age x 100 (+100) = You will qualify for National Championships
Age x 100 (+200) = You may be selected to play in a World Championships This formula only works for juniors (until age 18).

How does my rating compare with other Ratings; eg FIDE (International) Rating?
The ratings are calculated using the same scale as international ratings. See http://ratings.fide.com/toplist.phtml for FIDE ratings.

There are lots of different ratings. Many websites have their own rating system. Some chess clubs or associations have a ratings system. All of them try to maintain their systems as being comparable to the FIDE system. With each system there will be some variation, but most system administrators try to keep this variation from FIDE ratings to a minimum.

The Technical Stuff
The ratings formula used can be found:

http://www.fide.com/component/handbook/?id=75&view=article
http://www.chessclub.com/help/ratings
Tornelo offers both ELO rating calculations and Glicko1 methodology.For Glicko1 methodology see here.


Can I beat someone with a better rating?

Ratings are simply an indication of past performance. On any day, in any given game, anything can happen!Statistically speaking your chances of winning a game against a higher rated opponent are as follows:

Your opponent’s rating – Your chance of winning
50 points higher 43%
100 points higher 36%
200 points higher 24%
400 points higher 8%

How do I get a rating?
Every chess tournament you play will count towards your rating.

Any one event may be an uncharacteristically good or bad day, so your first Official Rating is the average of your performance over your first 20 games (usually about 3 tournaments).

After your first tournament you will have an Estimated Rating.
After your second tournament this will be a Provisional Rating.
After your third tournament you will receive an Official Rating.
Your Official Rating will then increase or decrease based on your performance in each tournament. If you play better than expected (expectation based on how you played in your first 3 events) then you will increase your rating. If you play below expectation, your rating will decrease.

The maximum rating gain/loss from any one game will depend on the seriousness of the tournament:

School Chess Tournament ±5 points
Interschool Chess ±15 points
RJ Shield ±20 points
State Level Event ±25 points
National Event ±30 points

Why do we use ratings?

To track your performance over time.
This give more accurate pairings in tournaments (ideally you don’t want to play against someone too good or too easy for you).
To compare your standard against others in your school, city, state, country or around the world. See Top Player Lists for your ranking.
To make a prediction about the result of a game or tournament.

Rating有几种，澳洲常见的是ACF，但是这个积分三个月才更新一次，而且在20局以内都是临时分数，一般是以X01结尾
国际上的积分澳洲很少使用，需要特殊比赛才能获得这个积分
还有一种是各个club，或者几个club联合使用的，这种积分就有很大差别了

不过不管是哪种，五岁的孩子能拿到五百多分的积分，都是很难得的了
很多七八岁的孩子第一年在二百分上下徘徊很久都上不去
你家娃这个点开窍很早，好好培养，大有前途哦

不错，很厉害。

5岁小朋友这个rating很棒的 。几个月rating会更新一次，如果赢的多而且是赢的是比自己积分高的人，积分会增长很快。

请问一下楼主参加什么比赛拿到rating的

今天翻到这个，觉得以前5楼给你的信息不对。NSWJCL有他们自己的等级分系统，并不能一对一地转换成fide等级分。参考一下这个 http://www.chesschat.org/showthread.php?7325-NSWJCL-rating-system

When I last looked at all this stuff back around 1999/2000 the rating formula seemed kludgy.
On top of that there appears no reliability in the conversion method from junior to adult ratings.
The system also has a rating floor round about 250.
Once your rating reached 250 your rating was not decreased by any formula but only by the number of successive losses you had. Apparently one of the lowest ratings was then 230 after 20 successive losses. A rating of 200 is supposed to be equivalent to a player who knows how to play but loses ALL games.


The rating formula they use is as follows (June-September 2002 (Number 93-94) NSWJCL magazine):

New Rating = old rating + C (C=Change)

Games are processed one at a time. For each game C is determined from:

C = (W + B*sqrt(D/400))*A*F*L

W = 0 if the game is drawn else W = 1 (The value W is applied to both players)
B = -1 if the higher rated player wins else B = +1 (Making C bigger for upset wins)
D is the difference in ratings for the two players (If D is greater than 400 it is set to 400)

A is a factor that varies with the status of the event. A varies from 10 for most games to 20 for the U18 at state or Australian Championships). Exception if your rating is decreasing then A=10.

F is a factor which varies with the result and relative ratings of players.
Winners and lower rated players who draw F = +1. (It is the postive sign of F that makes C positive, increasing the rating)
Losers: F = -0.7 (I have also seen this published as 0.8), Higher rated player who draws: F = -0.5. (It is the negative sign of F that makes C negative, decreasing the rating)

L is normally 1.


Now supposedly a rough conversion of NSWJCL ratings to adult ratings is as follows:
for ratings less than 600 then adult = 2*J
for rating greater than 600 adult = (J*1.25) + 450

NSWJCL自己网站上没有任何信息，只能拿这个10年前的老贴做下参考啦。希望现在也没有什么大变化。帖子里说的adult rating也不知道是不是就是fide，还是ACF。

以NSWJCL网站首页的2017男子少年冠军为例，他的fide等级分 standard：1996，rapid：1831， blitz：1873. 他的NSWJCL等级分是1116. 貌似基本符合以上转换法。

5岁多的孩子NSWJCL 409分那么大致是fide 800多分？按5楼的评估方法，真的是很厉害啦。难怪其他家长都恭喜你们。

请问在哪里做rating？

恭喜恭喜，楼主的娃又称为棋手的资质。

刚看到此帖，曾为NSWJCL工作多年，也有义务替他们解释一下。

LZ孩子第一次参加的比赛应该是NSWJCL在假期举办的One-Day Tournaments，获得Rating，409分也应该是NSWJCL的Rating。

现在已经事隔多月，LZ也应该知道孩子对 Chess 的兴趣和天赋吧。

409分在８岁以下组大约能进前１０。对于５岁孩子来说，的确非常好。LZ应该为孩子感到骄傲。很多中学校队的棋手，Rating比这还低。

不过也要提醒一下，初次Rating通常偏高。Chess 界的华裔神童越来越多，年龄越来越小。

自己孩子初次比赛时，也曾一飞冲天。从最底层开始，过关斩将，一直冲到一号台，与当年的NSW冠军对垒。当时我还以为自己扼杀了一位国际象棋大师。然而，转眼间，孩子败落，之后一蹶不振。大师梦瞬间破碎。天上回到人间，感觉更轻松。

不管怎么说，下棋对孩子的智力发展有很大帮助。NSWJCL 排名前面的孩子，大部分都是JR，BHH，NSBH学生。

较个真哈， 409在现在的u8排15名

如果第一次比赛就在后几盘杀到了第一桌，对垒NSW冠军，那真是很有天赋的，为什么不坚持下棋了呢？

随手拿到的是２年前的杂志，那时候，u8排10名刚好是409。我也知道，现在神童越来越多，年龄越来越小。

孩子第一次比赛，不是在后几盘，而是从一开始就一路过关斩将，一场不败，挾着天下无敌的气势，杀到了第一桌，对垒NSW冠军。当然，后来才知道，后几盘杀到了第一桌的才是真正高手。后来，孩子仍然继续下棋，一直是学校棋队第一棋手。不过，除了学校之间的比赛，重上第一桌的机会就不多了。

年级越大，水平高的越多。尤其是到中学后，还能保持这个爱好，不容易的

多谢各位，我的意见是孩子有兴趣就做，没兴趣就算了。他现在喜欢下军棋，我就正好借这个机会让他学学中国字

楼主儿子真是干什么都行。

孩子可以几岁学chess呢

孩子可以几岁学chess呢

大部分学校是一年级开始学，有些是prep开始，也就是六岁左右开始
刚开始上手很简单，后来有很多战略，小小孩不容易理解
但是只要有兴趣，见过很多八九岁开始进步神速的，只是后来不一定有时间下而已

羡慕。能问个问题吗？儿子不到五岁，聪明好动想让他学习下棋能稳重些。现在英语听力不够好会影响学习下棋吗？谢谢你。你在墨尔本吗？再次感谢
