11. Bd3. If 11. ... cxd5 then 12. hxg6.

Absolutely, 11. Bd3 and then I think black will have to play 11. ... Qe8

Interesting choice. How about Qg4?

...hxg6?? and white responds Qg4, Qh3, and Qh7#. Black has no moves to stop this mate.

I'm thinking Qe8 is black's only hope, but it's fading.

Why not 11) ..., h6?!

12. Bxg5 then. Now 12. ... hxg5 is impossible due to 13. Qh5 and mate is then inevitable.

11. ... Qe8 probably followed by 12. Bd3

I don't see how its worse than Qe8 right now. h6 with the idea of Rf6 and Qe8; white threatens Qh5 Bxg5

Missed kbauman's post... what is the mating line? I thought Black had escapes on f8/g7 (should Black Qh7-h8).

...But white does get his queen and bishop back... h6 Bxg px Qh5 Rf6 Qh7+ Kf8 Qh8+ Bxh8 Rh8+ Kg7 Rxd8.

Not sure what the evaluation here - but Black's development is bad. I think e7 falls at least ... Black is very cramped indeed, white has to be winning.

So h6 doesn't work after all I think. What is this forced mate idea?

Sorry, my bad.

However, I found another line to prove why 11. ... h6 12. Bxg5 hxg5?? needs two question marks. White has an immediate win after 13. Rh8+!.
Now black has a few ways to get mated:
1)13. ... Kxh8 14. Qh5+ Kg8 15. Qh7#
2)13. ... Bxh8 14. Qh5 Rf5 (14. ... Rf7 15. gxf7+ Kg7 16. Qxg5, if 16. ... Kf8 then 17. Qg8#, if 16. ... Kh7 then 17. Bd3🙄 15. Qh7+ Kf8+ 16. Qxh8#
