Bullet chess is it worth trying to get better at?
Bullet is hard.
yes, because of the time. I lost easily 20 games were I was plus 10, because I couldn't drag my mouse within .20 of a second and lose the game I was dominant in. Then comes the rage tilt followed by losing in legitimate time controls like rapid.

I kinda just play as im drifting off to sleep. I view it as Garbage, because you can be up 10 points and loss with 0.2 seconds. Lost many in this way.
