You blame your opening. It's not your opening. I promise you, it's not your opening.
Below about 1500, games are decided by three things, in this order: hanging pieces, missed tactics, and rushing. Fix those and you climb. Here's how to figure out which one is quietly costing you the most.
Leak 1: you hang pieces
The big one. You leave a knight defended by nothing, your opponent takes it, and the game is basically over on move 12. The fix is a boring pre-move habit: before you let go of a piece, scan all of yours and ask "is this defended? is it attacked?" Drill the shape with hanging pieces until spotting a loose piece is a reflex, not a search.
Leak 2: you miss tactics (both directions)
You don't see the fork that wins their rook, or you don't see the fork that's about to win yours. It's the same skill pointed two ways. Forks, pins, and skewers turn up in almost every game you play. Grind puzzles daily and they start jumping off the board at you.
Leak 3: you move too fast
Most beginner blunders happen in under five seconds. You spot a move you like and you slam it out. The fix costs nothing: once you've decided on a move, wait. Ask "what's my opponent's best reply?" before you commit. Do only this and half your blunders disappear.
Find your specific leak
General advice only gets you so far. Take your last five losses and find the exact move each one turned on. Paste them into the Guru's review and it'll tell you which it was: a hang, a missed tactic, or a rushed move. Once you see the same mistake three games running, you know exactly what to drill.
Then go fix it. It's all free on aichess.guru. And once the blunders stop, read how to get better at chess for what to work on next.
