How do you determine your OTB rating?

It's like playing chess online, if you play other rated players you get your own rating, you can't ask the same question and get the same answer and then ask the same question again,

Obviously, the answer is the same, get a rating from rated players, like 1500 a 200 a 600, there's no translation its a different skill group, chess.com gets ratings by what rating you fit into at your skill level,

BRO TEN YEARS HAS PASSED

I know bro. Still the same website, though.

but it doesn't even work unless you do tourneys irl

That's the point.

OTB is over the board (playing chess with physical chess pieces on a board).

Like this:

Do you get a OTB rating after you play in any tournoment that has some FIDE connection or do you need to request one or...

?

If you play in a rated OTB event, you will get a rating. Most OTB events are rated. In the US, most events are rated through the the USCF, but there are also FIDE events (usually only the top sections of large tournaments).

Just the rating that you get by playing over the board (OTB) and no by playing online platforms like chess.com

I don't know. Why do people complain about posting on old threads on knockoff social media?

you also post...

that's true indeed haha

You look up your name. https://ratings.fide.com

One reason is that very few new threads are of any value.

For those in the US, https://www.uschess.org/msa/

For Australia, https://auschess.org.au/rating-lists/

The best way to determine your OTB rating without playing in a tournament is this, play a ranked player 10ish times and let them watch you play other people. Then they will probably be able to determine it for you.
