Take back a move and mate instead

White takes back a move, then mates in one

difficult, i was thinking the King had just moved out of check on e6 until i asked how the bishop got there...

Take back fxe8=R



and play fxg8=Q#



I'm probably missing something. I never get any of your puzzles right.

Trouble is, this position is illegal!



Black's pawns captured 8 times. There are 6 white pieces on the board, and Bf1 and Bc1 died at home. That accounts for all 16 white pieces.

To promote a 2nd light square Bishop, Black would need to capture again ... but there is no capture available!

Yep, I knew it. I figured you would come back and either say the second bishop was illegal or that there couldn't be a pawn at f7. I really hate your puzzles. 😠

Take back Kxe5 and play Rxg8#

Ah! So this was the position after the knight moves from f7.



I never considered a discovered check!

Very nice. 🙂 You are one sick bastard though - you know that, right?

Actually, the composer was W. Naef, but I'll take partial credit for digging it up and inflicting on RHP members.
