There are more weaker players on chess.com than OTB so your rating will be lower if equivalent. To find out how much, you need to play OTB!

You probably won't play to the strength of your chess.com rating... maybe 200 points below at first (whilst you are gaining OTB experience). I'm around 2200, on chess.com, but my converted ECF rating is around 2050.

Am I going to get owned by a 1050 OTB player?
Find some tactics to solve (it could be chess.com TT, doesn't matter where) and set up the position on a real board and try to solve it.
If you've never used a 3d board you'll notice it isn't as easy at first (same for people who played on a board all their life then tried to play online for the first time).
After you get used to it, it's fine, but it might take a week or so of practice.

Ok it's just my opinion, based on my own experience.
I think that your highest rating is your average strength also OTB and your best win would be your top.
So for example mine average would be around expert level which is my highest around 2000 and my best win would be my top I can do which is around 2200 so I'm in this range category.
Same goes to you you average around 1200 and your top around is 1300 so you are in a range 1200-1300 player also OTB .
Roughly it's pretty accurate.

So you think OTB rating is very similar/a bit higher than online? I'm not sure most people would find that.

Depends on a which pool.
3|0 mins pool is definitely very similar if not stronger your rating online compare to OTB
3|0 pool is very strong a lot of title players play it .
I mean even people like Shahade in his last video played 3|0 pool players and was crying like a baby loosing all the time and he's IM and his rating pretty similar to OTB even a little less.
I play alot OTB and when I play CM people in real life I feel it's much easier compare to 19 hundred players in here

The blitzratings is not very different from fide otb longchess, but it depends of how fast you are. Fast players around 1200 is typically fiderated below 1200, while slow 1200s is typically fiderated above 1200.
By accident my blitz chess.com and fide longchess is almost equal these days, but I expect to gain a lot otb rating soon. I am a slow middleaged man.

That is right but I don't think it is reliable. First 265 data sets seems to little and then we know that there are ways and tools to get a better rating here. On the other hand players who have a FIDE rating maybe are more serious even on chess.com and do not cheat so much. But still if you want to know your FIDE OTB rating then start to poly OTB FIDE tournaments.

I did hear that in the Netherlands ratings are tougher - i.e. someone with a 1900 Dutch rating is tougher than someone with a 1900 FIDE rating!
Good luck - and as others before me already said - win or lose, enjoy the experience!

I agree. The only way to know is to actually play in tournaments.

Thanks everyone!
I should have mentioned its going o be a rapid OTB tournament. There are strong players, only maybe 10 1000-1200 KNSB rated, rest are around 1800 and even 2 FM's. This is going to be fun.
I hope my rapids on chess.com have paid off.
I've played some OTB at a local chess club the past month. I got beat each time, but the players were mostly 1500s probably. The last match I had in hand, but my opponent won, but this was before I started playing rapid frequently on chess.com.
It's going to be 90 minutes with 10 seconds after each move added.
Follow up question: tata steel is FIDE, is it wise to participate in it? Is there even a beginner/amateur pool?

I agree too. A 1200 chess.com is ready to take the plunge into otb-chess. Enjoy the experience! The thrill to play face to face with a tense human, thats exciting. Longchess also gives time to make well thought moves, and if it gets to slow, waiting for the opponent, you can walk around and look at other exciting games. After the game you can analyze with your opponent and learn a lot. In one tournament I got IM -help (IM Johan Sebastian Christiansen)with analyzing. Interesting!
If you're chess.com is 1200, what is your OTB FIDE then?
Can't imagine it to be just a thousand. I'm 1180 ish now, soon to be 1200 I hope. Man it was a little hard getting here to be honest. You have to keep attention to not let pieces hanging, find the right tactics etc.
Next week im going to participate in my first tournament (rapid 90 minutes, 10 second increment), as an unrated player. Will get a dutch rating after 6 matches ive heard. The lowest rated are between 1000-1100.
Am I going to get owned by a 1050 OTB player?
