How not to blunder

Watch master games for as little as ten minutes each day. You then pretend you are playing those games, and every time the master makes a move different than the one that you would have played, try to see why they played that move and not the move you would have played. If it is your tactics that are weak, try also playing slow time control games and work on the tactics in chess.com. You might also want to search up basic traps and techniques as well as play a player better than you. Also, if you have time, check out my blog (RALRAL3333's Blog) where I post chess puzzles I have created.
