    That was a tough nut to crack. Black has only one spare move, which must be a queen move, allowing the h-rook to pass to b8. The white knight must make a detour towards g1, to avoid checking black. And the white d-pawn must lose a tempo for two reasons: to get the number of moves correct, and to avoid arriving at d7 before the e7 square is available for the black king.

    Interesting synopsis. The composer would say that the King is on f6 to eliminate the other 4-move N paths from c3 to g1.
