very interesting, thought black was better but it took several views to see how trapped black really is...

on the one hand i go like damn if already 1700 see thngs i do not see i never be good in chess on the other hand, man didnt white have a totally winning position anyway? why risk everything with a complicated line

White had a clear edge, yes. Risking was aybe not the soundest way to win, but the only forced way. And the most fun. It's impossible to calculate all the lines, in a game, it took the computer around 1 hour to change the evaluation from -6 to +6. And the computer excels at tactical chess.

but anyhow i would have thought 1700 wouldnt be able to play such sacrifices, at least not sound.

Depends on the day, I am 1700 online with 60 games going, a bit stonger when it is OTB and a single game, and I love to try sacrifices so every now and again I am bound to find a solid one ;)

and yes in a serious game I would be less likely to play the queen sac since I was already winning, but chess is about having fun, so sometimes you have to through it all on the line

Oh, ok.

Wow! 

I like this queen sacrifice. Analysis on page 2!

Rxf6, (takes the knight) and black is better.
