tips to avoid blunders

I almost always review my blitz games with engine after finishing them, and I have found that I make stupid 1-move blunders in more than a half of my games. This results in making generally well-played +3 positions equal or losing an equal game instantly.

I understand that everyone makes blunders, but I find my amount of them quite excessive (and very annoying of course). I would very much appreciate advices from 2400+ players on how to minimize them.

Play Rapid instead.

I am mostly interested in blitz/bullet for now.

blunders are like my meal whenever i play chess, not just blitz and bullet. in bullet i make blunders a lot if i desperately try to win on time. the worst losses were when i played random pre moves and quick moves in opening, and made blunders instead. i did that because i had lost on time in bullet games in winning positions a few times. i also am not into rapid. i don't like long chess. maybe i can tolerate sometimes but not often.

Let me give an example from my latest game. After qa8-qb8 I find during the review qc6+ qxe6 winning a piece within 2 seconds. Instead in the game I played absolutely useless qxb8 losing all advantage, managed to blunder again later to completely lost position. Thanks to opps mistakes I managed to equalize and flag him after, but these 2 blunders was the most important part of the game for me.

Look at this 5 minute blitz game by Fischer

See his comment on his 30th move:
"At this moment my hand hovered over White’s Pawn on e4, but at the last second I realized that 30...Nxe4 is answered by 31 Qxe4 and White wins."
Conclusion: always check your intended move is no blunder before you play it, even in blitz.

Chess without blunder are boring.

Just try to pay attention to what is going on.
