Fun Fact of the Day: In chess, the knight can visit each square exactly once.
Once. Only one time. Never a second time.
I just had one of those moments where I thought “Wo! Can that be true? Only once. But couldn’t it move to somewhere it had been once it had been everywhere once? Like, what if you’ve moved your night 64 times and you needed to move it again?”
Then I turned my brain on.
Oh yeah
