Advantage after 2...hxg6

After the line you propose, this is what happens:
4. Qh7+ Kf7 5. Qh5+! Kf6 6. Qf5#

Advantage after 2...hxg6

Thanks! Sometimes I overlook the simple..... even after 5 minutes of staring at it......

extrapolation

there are a couple of ways it could go, actually (besides the way that pcarlisi pointed out). These are the two further progressions that I could see:

the first:

1... Bd4
2. Rxg6+ hxg6
3. Qxg6+ Kh8
4. Qh7#

the second is a little longer and assumes that black's king will once again retreat to g8 (instead of moving Kf6) white plays 5. Qh5+:

1... Bd4
2. Rxg6+ hxg6
3. Qxg6+ Bg7
4. Qh7+ Kf7
5. Qh5+ Kg8
6. Bh7+ Kh8
7. Bg6+ Kg8
8. Qh7#

in any case it should now be clear that 2... hxg6 is extremely disadvantageous for black and could very well lead to mate.

Can someone explain?

why black moved 3... Bf6 instead of 3. ... Ke8 ?
