is playing chess while your brain tired is a bad idea?

ive been tired all day for working long and saw i was getting worse when i am tired, so should i play chess only when i am not tired?

It is better not to play when you are tired: you will lose and feel bad.
Better solve some puzzles or study an annotated grandmaster game.

I have chronic insomnia...No wonder I don't play much.

Bruh your almost 7-year-old account only has 38 games :O

It's not a bad idea, it's a very good idea for your opponents.

If you want to play your best chess, don't play when you are tired.
If you like playing chess anytime, just do it! May casual games??

One method of training is to do your hardest training when you are fatigued. Being able to plow through difficult positions when exhausted will train you to be better on those final rounds when your energy has been spent. It's a real thing.

So, train when tired.

Play when rested.

If I want to play when I'm dead exhausted, I don't play on Lichess.

A very bad idea. Because your brain is already tired! No need to make it worse!
