I've run into this occasionally and nobody seems to know the answer.
Maybe somebody here does.
You are in the end game with the two kings and not much else on the
board.
We know, of course, that the king never can move into check.
For example...
White king at E5
White rook at F2
Black king at G5
Normally the White king could not move into F5 because it would be in
check from the Black King in the next square.
The king is never captured. He is mated when he theoretically could be
captured on the next move.
In this case, with the White King at F5, the Black King could not
(theoretically) capture the White King because it would be moving into
check by the Rook at F2. So is it legal for the White King to move
from E5 to F5?
Thanks

That's right. Like sumo wrestling. You step out of the ring, your
opponent steps out half a second later - but you lose.

It doesn't work that way, even a King that is defended cannot move
into check from the opposing King. Basically, the reasoning is that it
doesn't matter if your opponent loses the game the turn after you have
already lost the game.

Another one that sometimes comes up is this: white has a bishop on b7
and a king on b1. Black has a rook on c6 and his king on d5. The
bishop is pinning the rook to the black king so that it cannot move.
Can white play Kc1?
As Ted says, he cannot, as Rxc1 would end the game immediately and
white has no time for Bxd5.

No. The right way to think about this is if the white king moves from
e5 to f5, then the Black king can capture the White king first, before the
white Rook can capture. Once your king is captured the game is already
over. So it is not legal.

The two kings disappear from the hoard, like in Go, leaving just the
rook on his own, erect and sublime for one moment in time, aloof,
confused. He travels the board forever.
