Watching 10 second games. How do they move that fast?

10 seconds, .1 increment.  They move faster than I can move my eyes.

Are they using a mouse, touchpad, Neuralink, touchscreen, or?

Multiple premoves.

I was wondering the same. What is multiplay premoves?
Avatar of Fet
MULTIPLE premoves. Let me explain. Premoves are when you make a move before your opponent does, and if it's possible, it will inmediately (in 0.1 second) be played. You can also premove multiple times. That is multiple premoves.

Fet, the thing i don't get about premoves is, i've read that on bullet they often premove up to 30 times. (!!!). how is that possible? does it mean they are actually anticipating the responses of their opponents? or are they just spitballing?

Premoves, yes. But if you look at the game I posted, by move 10 (probably earlier) they are obviously reacting to each other's moves, sometimes in .1 second or less. How is that even physically possible?

yeah OP, i've seen that too.

that GM dude Brewington Hardaway... i've watched him find combinations for mate in 10 second games. Insanely, madly, impossibly good. i guess when we're watching those top boards, it's important to keep in mind these are super-GMs, like the best 16 players out of 7 billion. Guys like Hardaway are like another species.

It's 10 sec. You have to premove everything. And you need good reaction time and fast calculating skills too.

Anyone know what kind of input device they use? I assume a mouse, but mouse seems not conducive to moving that fast.
