How can i stop blundering and get better at chess?

Hey, If you want to win a game you don't necessarily have to look into your opponent's weakness, but it's all the better if they do have one. Instead, it would be best if you were looking for what moves you can do to trap their pieces, learning openings, and gambits will help you a lot since you are having a hard time memorizing them. To help you with that I recommended ChessMood, it's an online chess course designed by grandmasters to help you get better at chess. It has helped me a lot; they have tons of videos that help you where you're missing.

Thanks for the suggestion, I’ll check it out

I already play 15/10, and my school has a chess club that i've been going to with people similar to my skill or elo. Also, what is the main idea of the Caro Kann? Thanks
Main Idea of Caro-Kann is to built Pawn structure that identical to London System by activate your bishop but without d-pawn on d5.
Every Common Line been explain it on annotated above.
My advice (as a chess coach and 2100+ player):
Learn and apply the most important principles of chess.
Always blunder-check your moves.
Solve tactics in the right way.
Analyze your games.
Study games of strong players.
Learn how to be more psychologically resilient.
Work on your time management skills.
Get a coach if you can.
Thanks but, whenever I play games I see a screen of "1 mistake, 4 blunders," and all that, yet I don't know how to blunder check because I like don't see where the blunder is. And the blunders that I actually see is just a mouse slip. I also watch Topchess and he always explains what he does and he's (from what I saw in a vid) 2100+ elo. Also, what does time management and psychologically resilient mean chess type? Does it mean like dont get angry when you lose and analyze what I went wrong and dont stress out on ur time like that? Also, do lichess tactics trainer count? Thanks for the information though.
