Thanks Tony, now I have clear about it. My next question would be, how to know then your rating?

But this is just in USA, right?

Sorry for the big amount of question, all of this is new for me.

Thanks for your patience

Yes and no. There is (or was - I haven't kept up) an online based rating system that's been going on for a while (IIRC it was called "Ratings Central").. several people who post here have ratings on it. I'm not exactly sure how it works - it's apparently been adopted for use in some countries, who find it useful for the same reasons the USATT uses a ratings system. There are two problems, though. The first is, maintaining a ratings system is a lot of work - someone has to tabulate all the results in a tournament into the software. So for it to work in any particular country, some sort of mechanism must exist where this is formalized - tournament organizers have to forward their results to some person who's in charge of entering the data. Over time, this can break down if it isn't backed by a national organization. The second problem is - when you have pools of players who don't play against each other (as you do when the players live in different countries and only participate in tournaments in that country), the ratings for each of these pools will begin to diverge from each other. So someone rated 1200 in, say, Eastern Europe (I assume people would cross borders to play against each other within Eastern Europe) would be equivalent to, say, a 1400 player in Australia, and this would be equivalent to, say, a 1800 player in the USATT system. Trying to get all the regions synchronized (you'd have to rely on the odd person who, say, goes to Australia on holiday and plays in a tournament there) would mean periodically shifting everyone's rating by large amounts, which might upset some people. In the US, you have large, regional tournaments, as well as two large National events, in which people from many states participate. In addition, you have events where men and women play against each other, so the men's and women's ratings are all within the same system. Even so, there has been talk about "ratings islands", where the ratings of players in some large cities are "off" because the players tend not to attend tournaments outside the city.

Fantastic explanation. Thank you for taking the time to write and summarised all this knowledge. It is so interesting, and from this explanation I can get that this world ranking has more sense in general. At least this is my impression.

Thanks

You need to take part in rating tournaments to be able to gather your rating (in numbers).
There is some theory about, guessing your rating, but true rating is after you play many matches and have wins/losses and the data collected would give you a rating.

IE, in USATT, the junior boys champion is around 2500 to 2600 level.
But in Taiwan, none national team members can beat 25xx level players, so I'm guessing that there will be a handful of players that can just walk into the USA national junior boys team.
But of course, when they play matches, the results might not always be that consistent

This is that I thought with the last explanation in the line, that is difficult to have an objetive score or number that can be really valid between countries. Maybe the international ranking is trying to do that. At least I guess so.

Thank you for answering.
