two solutions

One of the solutions was easy to find. Follow the rule of "always check, it might be mate".
The second solution, even if I had known in advance there was a second, was a bit more difficult since it includes allowing white to put black in check.

What is that second solution?

Start with Kg6 rather than f5+

Then, sometimes white plays f5+.

Perhaps what schizoidman is referring to is that there are 2 possible ways to start;
1. Kg6 # 4 / f5 # 4

For 1. ... Kg 6 2. Ra8 h5 + 3. Kh4 Ndf5 #

1. ... f5 is the one we all follow. The other is left for much more refined spirits. Everything is pointed out in AMG
