How much does fatigue affect your chess performance?

Hi everyone,

I'm a long-time Chess.com player researching how fatigue, sleep, stress, focus, and playing conditions affect chess performance.

I've created a short anonymous survey (less than 2 minutes) and would greatly appreciate your input.

All ratings are welcome, from beginners to advanced players.

Thank you for helping with this community research.

I can't use the form but LOTS

Does playing drunk count?

if u r sick or tired or u have a trash live that of course has a negative effect on your chess or whatever. the same is when u r happy, healthy and so on it will have a positive effect on everything. u dont need to study medicine knowing this.

Yep that's why I'm not doing the form BUT

Although I don't think it helps, sometimes when I can't sleep I log on and play a few 3am matches. That's a good time to play too becaue people you wouldn't normally overlap with are on and you can get a ton of good passports.
