I've seen this and the trailer is enough to give me migraine

Hell yeah, I came in here specifically to post about those videos. Infinite chess gets extremely much more buck wild than you'd initially expect.

That's neat, I'd never heard of it before!

It is an open question whether an Angel of some power k can escape forever.

Looks like you're quoting the Proceedings of 11th Annual International Conference on Computing and Combinatorics from 2005: https://dl.acm.org/doi/abs/10.5555/2958119.2958180

Apparently, it was solved (twice!) the next year.

In late 2006, the original problem was solved when independent proofs appeared, showing that an angel can win. Bowditch proved that a 4-angel (that is, an angel with power k = 4) can win[2] and Máthé[3] and Kloster[4] gave proofs that a 2-angel can win.

That's how you recognize a technical drafter. That and handwriting only in uppercase.

You've heard of correspondence chess, how about commode-ance chess?

There are, they're just a bit out of frame.

I was gonna say, that's a pretty big nerf

And white finally has a mate in 3 moves!
