My Greatest Move?!

In this position, I played what I considered to be my greatest move. Can you find it? White to move.

Here's the full, admittedly bad game:

Which one of these moves do you think was my best?

Maybe the third? I will say that is the saddest black king I've seen.

One contender for my best move:

And the full game:

My other contender from a couple months ago:

Blueemu would never miss a chance to display his Mona Lisa.  And yeah, that Black king must've been experiencing claustrophobia.

Nice combo! 

Funnily enough, that was an unsound attack and Black was winning until Rae8. That's why I was hesitant to put it in, along with the fact that it seemed kind of easy to find, but it turns out I'm trash at chess and I was struggling to find brilliancies, lol.

The second one was nice, but it was the finish that put it over the top for me.

I'm still proud of finding the first one in such a scary position, so it's a tough choice.

He's 2200. You were so off in your prediction that I can't even understand it.

I was kinda guesstimating. I didn't actually check his rating.

It doesn't really matter. It's close, and it was an awesome positional/tactical attack, so I think you were basically right.

That is art. But I thought your greatest move would be your brilliant knight sac with g4 and h5, that went perfectly according to plan.

@little_guinea_pig's best move*:

*littleguineapig played g4, which is not the best move but this was a sattirical post.

I found out later that this is still theory, but I'm still proud of calculating the complications in a blitz game:

Bonus  points if you know what opening this is.
