I just cannot convert winning positions.

This is my typical game. My opponent plays bad, I'm winning, I blunder a piece, opponent rejects takeback, I lose. Don't look at the engine analysis, the whole game I'm pressuring and then I blunder! What can I do? You may say blunders happen and all but I blunder pieces much more often than my opponents.

And also, these blunder games come in streaks. I blunder in streaks and I'm currently in one. I got over this the last time by beating some 1900 rated player in an hour long game. I've DONE everything to get rid of these blunder streaks. Changed sites, new accounts, nothing works. They come randomly and go away randomly or after a good win.

What is happening?

And also, I don't know what has happened to my writing right now. Why am I using robotic language? No humour, no spicy grammar. Just... robotic "This is good. This was not bad" instead of "This is great! It was absolutely not bad." Is my brain just collapsing?

Maybe due to overconfidence...
Train more puzzles changing accounts sites and more won't work
Play with yourself on the board
Main key: practise and learn and do puzzles and don't play to much bullet and ultrabullet

Two solutions

1. To make a move that's faster than your opponent next move in terms of accelerating your attack.
2. To make a solid move that refutes your opponent main threat.
   PS.
   Finding the right balance in these two is prodigy

How's that supposed to help?

I'd recommend slowing down. After each of your opponent's move, ask yourself: is there a threat? Before each of your moves, ask yourself: am I missing anything? That's how I fix this issue when I get sloppy. I see this with a lot of players: once they get the initiative they only focus on their moves, and don't spend enough time thinking about all of the opponent's options.

"I've DONE everything to get rid of these blunder streaks. Changed sites, new accounts..."

In this case consider spitting on the floor and dancing with a banana on the head. Repeat "Blunder streak go away, go away, go away!". I know it's dangerous for mental health but such incidents require taking radical steps.

That's everything?

What you really should do is some studying. Overall improvement is the surest way to reduce blunders.

@d4c5only
Firstly, you badly need rest. Don't forget that sleep cycle is important. Have enough rests and don't make yourself tired. That is the greatest factor.
Secondly, you should play slower games initially so as to improve thinking skills.
If you just want to play blitz, then do puzzle streak, puzzle rush, puzzle racer in that order as time progresses.
And you should not play games at streak. After playing a game, you should analyse it and understand where you went wrong.
Also, after doing enough puzzles check puzzle dashboard to see your improvement areas. Then work on them.
I hope you will definitely improve.
All the best!

yes, you can ...

Don't listen to people giving you chess tips. These are not for you.

Your blunder streaks are a curse. You have to play opening repertoire consistent with your nickname, otherwise you make gods of chess very angry. Stick to the benoni or you're screwed forever
