  1.Ne6+!
  A>1….fxe6.2.Rd7+.
  A1>2…Be7.3.Qxe7+.Kany.4.Qg7#
  A2>2…Kh6.3.Qf8+.K/B any4.Qxg7#

  B>1….Kh6.2.Qf8+.
  B1>2…Bg7.3.Qxg7#
  B2>2…Kh7.3.Qxf7+.
  B21>3..Bg7.4.Qxg7#
  B22>3..Kh8.4.Qxf6+.K any.5.Qg7#
  B23>3..Kh6.4.Qf8+.
  B231>4…Bg7.5.Qxg7#
  B232>4…Kh7.5.Rd7+.Be7/g7.6.Qg7#.

  C>1….Kh7.2.Qxf7+.
  C1>2…Bg7.3.Qxg7#
  C2>2…Kh8.3.Rd8+.Bxd8.4.Qg7#
  C3>2…Kh6.3.Qf8+.Again var B23!
  C31>3…Bg7.4.Qxg7#
  C32>3…Kh7.4.Rd7+.Be7/g7.5.Qg7#.

  Hence forced mate in 6 which is variation B232!
  B232>1.Ne6+!.Kh6.2.Qf8+.Kh7.3.Qxf7+.Kh6.4.Qf8+.Kh7.5.Rd7+.Be7/g7.6.Qg7#.

  The shortest mate is in 3 as per variation B1
  B1>1.Ne6+!.Kh6.2.Qf8+.Bg7.3.Qxg7#

  This should be check on every move, making it simple (anything else would be utterly difficult for white here). It goes:

  1. Ne6+!

  Trying out the accepted sack lines:

  1. … fxe6
  2. Rd7+ Kh6
  3. Qf8+ Bg7
  4. Qxg7#

  2. … Be7
  3. Qxe7+ Kg8/Kh8
  4. Rd8#/Qd8#/Qe8#/Qf8#

  3. … Kh6
  4. Qg7#/Qh7#

  Lines declining the N sack:

  A)
  2. … Kh6
  3. Qf8+ Kh7 (Bg7? Qxg7#)
  4. Rh1+ Rh4
  5. Rxh4+ Bxh4
  6. Qg7#

  B)
  2. … Kh7
  3. Qxf7+ Kh6
  4. Rh1+
  is the same as A.

  Black can make this 7 moves by inserting the Q sack:

  4. … Qh3
  5. Rxh3+ Rh4
  6. Rxh4+ Bxh4
  7. Qg7#

  1.Ne6+ settles the matter.

  To see that Ne6+ actually works, you have to see (in the declined sack line) the later bishop deflection trick Rh1+ Rh4 Rxh4+ Bxh4 Qg7#.

  Without seeing this, the puzzle should be impossible to solve (unless you simply say Ne6+ by guess, but that isn’t a solution).

  Dear pht,
  I am caught off guard by you several times.All I had in my mind was(in declining line)
  1.Ne6+ Kh6
  2.Qf8+ Kh7
  3.Qxf7+ Kh6
  4.Qf8+ Kh7
  5.Rd7+
  the line Rh1+ never entered my head otherwise I would have enjoyed the bishop deflection theme the very essential point of the solution.Perhaps it is age factor.At 70 I fail to catch all lines.

  Dear pht ,
  Have you observed an alternate pattern in your (B) module.
  4.Rh1+ Rh4
  5.Qg7+ Bxg7
  6.Rxh4#
