Really nice question. I would never fins the answer if irontigran did not post his solutions. Thanks man.
White must play a check otherwise he is mated. Rb8+ does not work so white must devote all his time just to analyze last resort Qe6+ line.
1. Qe6+! Qxe6
2. Nd7!! threating mate by Rb8# and must play 2...Qxd7 to avoid mate next move.
3. Rb8+ wins.

The problem was that any line I found relied on black no playing 2. ... exf6
That's a really good problem.

Originally posted by Fat mans revengeI have to agree, really good. Like irontigran I was too busy looking at Rb8+ and seeing where that leads. If that had come up in one of my games I'd hope the time limits were set really high, because I'd have been considering resignation in that one... 🙁

Yeah...that looks like it works - ah, nope, the black queen has the c8 square covered so that's not mate!

Your solution doesn't mate.
Here is the mating solution:
1. Rb8+! Kxb8 2. Qb5+ Kc8 (2... Ka8 3. Qb7# ) 3. Qb7+ Kd8 4. Qb8#
This has been discussed before please go one page back please.

3...Kxb8 is forced
4. cxd7 [insert any black move here]
5. d8=R#
thanks to the a6 pawn.

Originally posted by irontigranIncorrect. 4. Qc8+? Kxc8 or Qxc8. But I suppose there has been posted a lot more. 4. Qb8+ Qc8 too, so that's no mate either. Bosintang has it wrong too. Kenan seems to have the correct solution: it is
1.Rb8+ KxR 2.Qb5+ Kc8 3.Qb7+ Kd8 4.Qc8#
1. Qe6+ Qxe6
2. Nd7 [threatening Rb8#] Qxd7
3. Rb8+ Kxb8
4. cxd7 with
5. d8=Q mate after any move.
Kenan's last solution is not fully correct either, since 4. ... c5 5. d8=R is no mate (5. ... Kc7) - 5. d8=Q is required in some lines. The problem was composed by Anderssen (1842).

Correct. Can you post the complete sequence? (it's mate in seven at most)
is the longest mate I think..I have a similar one on my mobile phone...I will try to post it now (that'w why I found it somehow fast)
