It's not that obvious, is it ? I see the continuation (1. hxg3) 1...Qf5 2. Qxc7
Bf8 3. e4 Qh5 4. f3 Bxf3 5. Ne3 and black is better, but not winning. The black
pieces on the back rank are very passive, and if white gets a rook on f1 or h1,
he'll make trouble.

I don't think Qf5 is specifically difficult for a computer. A human would have
to think about Qf5 very carefully too.
