This idea came from a puzzle a friend presented to me a long time ago.
It's a pity it is White's turn, Black has forced mate with (Nxd6), as all White can do is delay mate by Blocking with his rook, and then possibly block with the pawn if we assume that the pawns are actually moving that way.
It would have been more challenging if it had been black to move and mate in 3.
"Diabolically evil" is a bit much. It's not so much a hard puzzle as a mind game.
Is it me, or do self-styled trick puzzles always seem to involve pawn promotion?
WHY YOU LITTLE...
LOL....That was funny.
"Mate in 1. Thinking outside the box is a MUST!" gave it away.
I'm glad people like it. I felt i had to add that hint, otherwise it would be wa-ay too hard to figure out.
why won't it work by promoting the pawn to a biship
Sorry, if i could allow other options, i would.
