There is an interesting property to arbitrary chessboard configurations - it is impossible, unless the king is in check, to tell which player has the move (whose turn it is). Tightrope may be thought of as two puzzles in one because if it is white's turn, there is a forced mate-in-three (a classic knight combination), whereas black can force a mate-in-tour if given the first move (a queen sacrifice).

Position in Forsyth-Edwards Notation:

Win for white: 1. ♘f4g6+ ♕h7 2. ♘f8+ ♕h8 3. ♘e7-g6#

Win for black: 1. … ♕×a2+ 2. ♔×a2 ♘c3+ 3. ♔a3 ♖a8+ 4. ♗a6 ♖×a6#

A forced win for the first player
