100%!!!! If you train enough you can have a good shot! I would advise to do many puzzles. I like the ones in the woodpecker method book, but you don't have to do the actual method. It helps if you do, but just doing the puzzles in the book is also very helpful! I also think that playing longer games are helpful. Of course you might disagree with everything I say, and I don't blame you. After all, I am not that good of a player myself.
Rated as 1089 in USCF, rated on chess.com as 550, attending a tournament for u1200?

The gap between 1089 USCF and 500 Chess.com is huge. A player rated 1000-1100 should be around like 1200-1400 Chess.com. Can you tell us how many rated USCF games you have played?

But I think reaching 1200-1400 in 2 months is possible, but it will be hard. Imma recommend u some stuff:
Learn the Vienna Gambit Opening. This opening is really good especially when you are going to be playing U1200 USCF players.
Do tactics+puzzles everyday. If u don't have Chess.com premium go to lichess cuz they have infinite puzzles. This will help u find simple forks, pins, skewers, M1s, M2s, M3s, etc.
Play longer time controls. ur already playing 10+0 which is great, but if you would like to improve faster than I would recommend 15+10.
Make sure to blunder check all ur moves and see if it loses material or blunders like mate in one
Hello guys,
As you see in the topic my rating varies very weirdly across platforms, and I want to play a tournament where my rating places me as USCF ratings of u1200 elo section, but my play is consistent with those of a 800-900. Is it possible for me to prepare and get good enough for this tournament in 2 months, increasing my play quality to that of a 1200 and possibly trying to win the tournament?
please help with any advice
