Well done, and I am not criticizing as you may have seen your combination clearly, but I found 43...Qh7 simpler.  Assuming I am right, (I can overlook the obvious) 44 Bxh7 Rxg1+ 45 Kxg1  Kxh7 46 c7 b1=Q+    and are you not glad to have the check.  Their are other white lines that he may chose, but I believe they are similarly disasterous.   

@Escapest pawn: if my enemy answer with 44. c7 what will u do?

As I say, I can overlook the obvious, but doesn't just taking work?

The above ends with check. The "+" did not get cut and pasted.  And are there not other ways to play it.  

 45 N-f7+ is a clever sac that almost works.

As I said, I am not really arguing for it, I just would have found it simpler.

I just ask you. you have a good vision. you're right, its simplier move. thanks
