Hi
According to Stockfish I made mistake but I cannot find it.
http://en.lichess.org/nHZyL8QyI continued from the position and Stockfish had to resign basically.

f6 is a mistake only because c4 is more accurate.
24. f6 g6
25. Qh4 (Qg5 is slightly better) Nc7
26. Qh6 Ne6 (and black's knight saves the black king for a bit)
27. c4 (which is the only way to continue).
c4 was more accurate
Why c4 is more ?? accurate when f6 is thematic logical and no defanse against it?
Explain a bit more...I think Stockfish is wrong simply:)
You think wrong.
Stockfish was wrong. On the next move even it starts to change its mind as the evaluation jumps to +9.3.
f6 is a mate in 9 according to another engine. c4 is only about +6 after a few minutes.
I just posted the line up above.
f6 g6 Qh4 Nc7 Qh6 Ne6... what are you going to play next?
The truth is- your approach is simple and easier to see, but by playing c4 first you open up the d-file. And if black ignores it, it loses in every aspect.
By playing f6 first you'll eventually have to play c4 at some point once black's knight is on e6.
Ne6 stops Qg7#. See it?
Stockfish didn't analyze it thoroughly. f6 is a mate in 12# according to SF itself.

Hm I let it think a bit more and it's actually a mate in 9 # :D
