  1. Rf8 if Kf8
  2. Ne6 Kg8
  3. Qe8 Kh7
  4. Qe7 Kh8 or Kg8
  5. Qg7 #

  or in move one:

  1. Rf8 Kg7
  2. Ne6 Kh7
  3. Rf7 Kg8 (if 3. … Kh8 4. Qh6 Qh7 ( 4. … Kg8 5. Qg7#) 5. Qh7##)
  4. Rg7 Kh8
  5. Qh6 Qh7
  6. Qh7#

  Jorg, at first, I made the exact same mistake, but 1. Rf8 is the winner.

  1. Rf8 Kf8 (Kg7 below)
  2. Ne6 Kg8
  3. Qe8

  Really the only move possible since Qg5+ allows black’s queen to join the defense. Continuing:

  3. …..Kh7
  4. Qe7 Kg6 (Kg8 5.Qg7#; Nf7 below)
  5. Qg7

  Force black into the picket fence:

  5. …..Kf5 (Kh5 6.Qg5#)
  6. g4 Ng4 (Ke4 7.Qg6 Nf5 8.Qf5#)
  7. hg4 Ke4
  8. Qg6#

  At move 4 above, black is still mated after Nf7:

  4. …..Nf7
  5. Qf7 Kh6
  6. Qg7 Kh5
  7. Qg5#

  And, at move 1, black clearly can’t decline the rook:

  1. …..Kg7
  2. Ne6 Kh7
  3. Rf7 Kg8 (Kh8 4.Qh6 # next move)
  4. Rg7 Kh8
  5. Qh6 with mate on the next move.

  After the rook sac on f8 black has two choices:
  a) run and b) take the rook. Let’s look at a) first.

  1.Rxf8+ Kg7
  2.Ne6+ Kh7
  3.Rf7+ Kh8
  4.Qxh6+ Qh7(Kg8, 5.Qg7#)
  5.Qxh7#

  3.Rf7+ Kg8
  4.Rg7+ Kh8
  5.Qxh6+ Qh7
  6.Qxh7#

  Now let’s look at option b):

  1.Rxf8+ Kxf8
  2.Ne6+ Kg8
  3.Qe8+ Kh7
  4.Qxe7+ Kg6(Kg8 or h8, 5.Qg7#)
  (Nf7 5.Qxf7 Kh6 6.Qg7+ Kh5 7.Qg5#)
  5.Qg5+ Kf7(Kh7 6.Qg7#)
  6.Qg7+ Ke8
  7.Qf8+ Kd7
  8.Qd8#

  1.Rxf8+ Kxf8
  2.Ne6+ Kg8
  3.Qe8+ Kh7
  4.Qxe7+ Kg6
  5.Qg7+ Kf5
  6.Qg5+ Ke4
  7.Ke3+ Kf5
  8.g4+ Kf6
  9.Kxh6+ Kf7
  10.Qf8+ Kg6
  11.Qg7#

  Checkmate follows in other variations to like if Black decides to sacrifice knight after 8.g4+ Nxg4 9.Kxg4 10.Qg5#

  actually mo complicated like it seems, and once d white queen veers of its trajectory to keep the check going, the black knight could easily block the f-file and threatening the white king in reverse… i go with my earlier submission as enumerated. tanx! -john.
