This position doesn't give a side to move at the end. That's a good thing, because specifying the side to move at the end of a proof game is a violation of common courtesy. But unfortunately, the position is legal and doesn't belong in this thread.

Totally illegal. (#7593)
Too easy. No black king.
7590 is not legal. What was blacks last move?
In 7590, Black's last move had to be with the king or b pawn. But any square the king could have come from would have been checked multiple times in a way that's impossible. So it had to be with the pawn, but if it was with the pawn, how could the king have gotten to a8 with pawns on b7,c7,f7, and g7? A contradiction.
Then it should be legal.

#7590 is legal. Black's last move was Ke7-f8, followed (perhaps) by White's last move, Pd5-d6.
See #7593.
And how did the pawn check the king while the rook was already checking it?
Legal
Black only makes 15 captures, and white has 15 expendable pieces:

I posted this position a long time ago and was told it was too easy, but I still like it.
Why is this position illegal?
Just want to bump this one cause I still think it's the best one ever!
Legal
Both sides have more than enough captures:

You need to think a little longer before posting. The pawn never checked the king, which was at f8 when the pawn made its final move.
