[PUZZLE] Find the brilliant move!

Hello!

I have played a game, and I was clearly dominating my opponent. At least, my opponent did one brilliant move (after stockfish). Here is the the puzzle! Enjoy! You're playing white. Last move is ke5 from c6 for black.

gxf5?

Exactly. Black at this point, completly dominate the game. But there is one thing black forgot:

gxf5 is one interesting move, because you're doing an extra tower sacrifice.

gxf5 - nd3+

kb1 - bh1

And here is the draw pattern, forcing the king to do the same move, and the eaten knight cannot protect the king from the queen anymore.

On multiple chess, the king has always one way to go.

Considered as brilliant for these reasons imo.
