  Hmmm… you might want to re-check whether White is forced to play 2. Nxf2 or not. Hint: not.

  I think it’s mate in 7, though White can end it earlier.

  Curious about White’s under-promotion.

  Here are a couple of approaches:

  1. … Nf2+
  2. Nxf2 Qxf2
  3. Qg2 Bf3
  4. Kh2 Qxh4+
  5. Qh3 Be5+
  6. Kg1 Qd4#

  1. … Nf2+
  2. Kh2 Be5+
  3. Kg2 Nxh3
  4. c7 Nf4+
  5. Kg1 Bd4+
  6. Nf2 Qxf2+
  7. Kh1 Qg1#

  1. … Nf2+
  2. Kh2 Be5+
  3. Ng3 Nxh3
  4. Bxh3 Qxg3+
  5. Kh1 Qh2#

  Or, for someone who doesn’t read FEN notation:

  1. … Nc7+
  2. Kb7 Nxa6
  3. Nb6 Nc5+
  4. Ka8 Qc7
  5. Nd7 Qxc8+
  6. Ka7 Qb7#

  Or

  1. … Nc7+
  2. Nxc7 Qxc7
  3. Qb7 Qa5+
  4. Qa6 b1(Q)
  5. Bb7 Qxa6+
  6. Bxa6 Qb8#

  Let’s see another try!

  1. … Nf2+
  2. Nxf2 Bf3+
  3. Qxf3 Qxf1+
  4. Kh2 Bd4+ +/-
