Very Hard Chess Problem

Sort:
ChessDude009

In the position in the diagram, Black had decided to resign (although it wasn't his turn). White advised his opponent not to give up so quickly. "But I am bound to lose, and there is nothing I—or you, for that matter—can do," said Black. But White insisted: "I'll bet you $100 that I can lose!" So the two made the bet and White actually lost. He did not resign, lose on time, or anything like that. How did he lose?

Pretty sure the only way white is losing is if they are going down the board.

g7 surely

The white pawns promote on the 8th rank and it is White's turn.

This leads to mate...

If the position is White To Move, White wins by g7#

g7 isn't mate straight away. Also it's the only legal move. It's a riddle, we have to figure out how white was able to lose even though a win seems forced.

I don't see any way for white to lose unless they make an illegal move or reverse the board.

White can resign. That would be a legal loss. Looks like a 'bar" bet to me.

Opps. Bet says can not resign.

The only legal moves is g7+ to block the check, since the knight on g5 covers h7. The white pawn is protected and the black king cannot move (as the white bishop’s attack is revealed), so black must play Qxg7+ in return. This forces hxg7, which is checkmate since the black king cannot move.

So white lost the bet.
