I lose easily to players that spams all their pieces especially pawns without thinking in Blitz.
YouTube made me weaker

One more things that help me. I no longer do puzzle, lesson or videos. I only recommend magnus trainer app subscription for one month to understand how top players thinks.
When I started the game a month ago without knowing anything besides moving the pieces I easily got to 1300 rating in Blitz 7 days of playing. Now, I feel I've lost my unpredictability in my games after watching a bunch of YouTube Shorts and others playing. I can't even reach 1300+ in a month its frustrating.
