Participating in first tournament...how will it go?

Thanks ThrillerFan for fullfilling my curiosity. Regarding the fatigue, staring at a screen is really exhausting for the eye and the brain though.

UPDATE!

Actually participated in my first blitz tournament today! Time controls were 3 | 2 and we played a total of 18 games! Average opponent rating was 2100 and I got 2 score out of 18. 2 draws and 1 win. I should have had AT LEAST 5 score, one game I was up a pawn and gave away my queen against a 2200, another game I gave away queen against a ~1800 player and another game I had a draw against a 2300 but I did a dumb knight sac at the end that costed me the game. NEVERTHELESS, I played really bad chess and could have done so much better but according to initial FIDE rating calculator my rating should be roughly    1749.  https://ratings.fide.com/calculator_rp.phtml

Ah. Thanks! I dont think that is quite right. I am 1700 USCF (1701) and 1400 fide (1438) so i dont know how that correlates. However, I try OTB, where online i often play the barnes 

Good responses!
yes, it was a different feeling plating OTB than online but I have to say, since I had really good positions with FMs, CMs och people with 2000+ rating that it isnt particularly harder than on chess.com. People who claim Chess.com ratings are deflated aretotally wrong! I’d estimate my fide strength to be 1900 blitz which is roughly the same as this site. 

After looking at some of your daily and Rapid games I think you will be around 1650-1750 Fide. You are very fast but you do not know much about chess. The quality of your moves in Rapid is not much better than in blitz so the extra time in classic otb will most likely help ur opponents more than you.

That does of course not mean that you cannot improve over time. Just go for it and try it out. Good luck!

I do play long time controls as well and am roughly 1700 rated rapid here. However I avoid it because I keep getting notification messeages from chess.com constantly that I have gotten extra elo points because opponents broke fair policy (aka used engines and cheated).

On top of that if u look at rating distrubutions they seem to be lower on rapid thus I’d say a 1700 rapid rating probably corresponds to higher than 1700 fide - this as pretty much 99th percentile on chess.com is already at ~ 1900 rating. 

I do not really understand your reasoning.  I guess you are playing rapid games in order to get more experience at playing "longer" time controls. and not in order to get an as high rapid rating as possible.

Hence, why does it matter that you occasionally run into cheaters? A few times I got totally crushed playing black in the sense that the game was totally lost after 10-15 moves. This only revealed to me that I did not understand the opening white played at all and should invest some time in understanding it. The fact that my opponents did get banned later does not change the fact that I responded very poorly to the opening choice of (the engine).

Don't worry about the results at all and use it to learn as much as possible.

I'm sort of in the same boat having recently picked up club and external competition again after a decade of absence.

What works well for me is to try and really understand positions and for that I need a LOT of time.
Not only do I learn a ton each game that way, generally get good positions but it also lures my opponents into thinking I'm a slow poke which often has them playing faster and their quality suffers.
Once I have less than 15 minutes or so left on the clock I have little trouble kicking up a bunch of gears (we have a similar blitz rating) which has a tendency to catch them off guard again.

You might be a little surprised by the level of play at first. Routined 1800 OTB guys are Good. They don't seemingly miss a lot and it's about strategy and digging for small advantages/mistakes from which tactics might flow eventually.
So it's a slight switch from tactical blitz mode to long term strategical super precision mode but very rewarding.

 Out of curiosity, what is your Fide Elo WobblySquares? We have a roughly similar blitz and rapid rating, so I wonder if our OTB ratings correspond also.

Interesting remarks WobblySquares! 

Awesome advice!

UPDATE!
Currently participating in a tournament and played my 3 first rapid games today, ended up scoring 2/3, completely blundered away my bishop against a 1770 elo guy.

Here is a game I played against a 1611 ELO rated player, didn't even bother thinking too much and I only used 17 mins on the clock, opponent used 40.

I PLAYED BLACK. 

 ANOTHER update:

Have a 2.5/4 score. Average opponent rating 1750.

Drew a 1855 guy yesterday. I guess my 1850 blitz/1700 rapid on chess.com corresponds to roughly 1800 FIDE STD.

Yep I know but seeing as I’ve played a 23 round blitz tournament and also absolutely crushed 1600 std players on 1hr+ games it’s an estimate that my rating is definitely somewhere between 1700-2000
