Nice, pawn to c3 and the queen cannot move to a square that the knight cannot fork it with the king.
Edit: yes, the queen can take a pawn, but im sure c3 features somewhere in the solution, either first or in a move or so, with the effect of forcing a fork.
Edit 2. Does c3 Queen takes f4 g3 trap the queen? Im tired and cant visualise too well, and cant be bothered to imput the position onto a board.
Edit 3. Queen can escape onto the h file therefore pawn to h6, gxh6 c3 Qtakes pawn g3 traps queen i think.
The white bishop and knight are superbly positioned. 1.h6! and white threatens either a promotion of the pawn or deadly knight forks after gxh6 2.c3! Qxf4 (only escape from a fork) g3! no escapes anymore 1-0.
