I noticed that in many of your games you move rather quickly even if you have a large amount of time on the clock, which results in blunders and misses. Make sure to focus on why your opponent moved somewhere.

Fix tunnel vision and board vision. Im 700 elo and after doing some vision training i can easily gain elo

Not only that, i beat 2 1000s 4 800s.

Do puzzles for a while but make sure you don't get addicted to them, game review helps a lot as well if you have premium and make sure you watch high levels players and learn from them too.

Yeah I beat a few 2200+ players from time to time

Good afternoon, please, I need you to clarify a question for me. in an impthetic move where my king is attacked by a rival piece but is covered with his own piece and it is my turn. Is the move prohibited where I take out the piece that protects it and my king is automatically exposed to a checkmate by the opposing piece?
