Does limiting your blunders actually improve your game?

I’ve been trying to fix one consistent issue in my games: blundering under pressure.

Even after solving puzzles regularly, I noticed that in real games I still make avoidable mistakes.

So I tried something different using a smart chess database.

Instead of solving puzzles normally, I gave myself a rule:
→ I’m only allowed 4 mistakes per run
→ If I exceed that, I restart

It feels very different from normal puzzles:

• You can’t just guess moves

• You’re forced to slow down

• It feels closer to real game pressure

I’ve been testing this for a bit and it’s surprisingly challenging.

I put together a small version of this mode here if anyone wants to try it:

Also added an option to connect your account to analyze your games and spot where blunders happen most often.

Curious what others think:

• Do puzzles actually help with blunders?

• Would limiting mistakes like this improve consistency?

Would love to hear how you train this.

I think puzzles helps you alot, they make you think about the best move even when situation feels to be equal
