How to stop blundering?

Best advice I’ve seen in my entire Chess career.

I strongly agree with this

yes i agree one hundered percent. I hate this stupid game and wish I could quit. My dad forces me to play though.

I have an anti-blunder training program. It helped me reduce my blunder rate and also helped improve my rating from 2000 blitz to 2200+ blitz.

🤔 good question

Not a very good idea - You need to keep trying! (unless you don't take chess seriously), and set goals so you will aim for that goal.

To stop blundering, you need a simple system of discipline during games. Always perform a blunder check before moving by asking: “If I play this, what checks, captures, or threats does my opponent have?” Train yourself to scan forcing moves for both sides, since tactics usually arise from checks, captures, and threats. Avoid tunnel vision by considering at least two or three candidate moves instead of jumping to the first idea. Slow down at critical moments, especially when pieces come into contact or the position changes suddenly. In training, solve tactical puzzles slowly and carefully, simulating real-game thought. During games, make it your goal to play with zero blunders, not just to win. After each move, pause for a quick scan: “What did my opponent’s move change? What is hanging?” Finally, review your games and mark the exact point where your calculation stopped—that’s the habit to repair. This steady process cuts blunders over time.

It's very hard to completely stop blundering even grandmasters do it from time to time what I go for is minimising it by asking myself what they are threatening after they move

I have learned another one and i will suggest don't play when you are tired

"...have been improving strategically, I find myself making a game blowing blunder almost every game..."
Could it be that you have been studying more strategy and less tactics lately? Perhaps your focus has shifted away from the tactical part of the game?
