Nicely done!

Is the position a legally reachable one? How can 3 black pawns be in the h file and 1 in the f file?

If I am not mistaken, the black pawn on h2 could come from the d file. The one on h4 from the g file.

I would have found it much harder if I hadn't seen the respectable solve rate. That gave it away that:

(1) There had to be one concept that lasted most of the 29 moves, which led me up and down the staircase;
(2) Black was never going to be allowed to start a series of spite checks.

This, along with the fact that I was wondering why I needed to bother capturing an apparently useless knight on g8, meant that Qf1+ and final the mating pattern quickly came from the elimination of alternatives. Without (1) and (2) above, it might have been much trickier.

Congratulations blitzkov.

That was great fun. Really nice puzzle. Cheers.

The reason for killing the knight is that it cannot interfere the white knight and king checkmating the black king in the corner. If the black knight is still on the board, it can move Nxf5 and Ng3+

Amazing one! Just that... But the comment was too short to be accepted since I had to add something useless. Now I think it works.

i just didn't like the style of the puzzle back and forth, i prefer mates under 10 moves
but i understand your point of getting rid of knight it was set it a way that you cannot find any other way to mate lol

Am i the only one here that figured out a way to make this checkmate in 8 moves instead of 29? If you would like to know how then i will tell you. (1.Rxg8, Nxg8)(2.Qe3+, Kg2)(3.Qf2+, Kh1)(4.Qf2+, Qxf1+)(5.Kxf1,a4)(6.Nc5,h3)(7.Ne4,h4)(8.Nf2++)

Yes, not only avoid the mate, that way Black promotes and wins!
