The queen is supposed to be on e1. I've seen this puzzle. Queen b4 is the mate in 2 because it is blacks turn now and they are zugzwanged to a mate in one

I could say that the position is already mate since white appears to be in checkmate. There. Mated.

In fact, I'm not asking you to find a move that allows white to deliver mate in 1. I'm asking you if white is in checkmate already or not.

@SomethingStranger: If that was white's last move before ...c6-c5, the bishop on b8 must be promoted. Is there any reason that is possible, or impossible?

if there is en passent then it is not checkmate

It's hard to be certain about what the hardest mates in one move in the game of chess are, right?

But how do you know black's last move was ...f7-f5?

Dude, you have to figure that out. Otherwise how can you do the mate?

PS. Why did you show my solution?!!

I contend that your problem has no solution. That is why I did not bother to hide it.

Say you walked into a room and two players were playing this position. They've told you it's white to move. Isn't it far more likely that Black's last move was something OTHER than ...f7-f5?

so why isn't en passant legal in the puzzle? u should add it since u forgot
