Count me in the confused camp too.
It's not like your superior play was winning the day. Sure, you had snatched the odd pawn here and there (a style of play also open to criticism), but your opponent initiated the bad exchange on move 26, an unforced error, handing you a winning position. You didn't outthink your opponent, you had good luck.
And then when you returned the favor, your opponent is now the bad guy? As I said, call me confused.
I kinda get where you're coming from now. Someone on my friend list plays just like that. Mindlessly chucking knights around the place and hoping for blunders. He wins a game here and there but it's not the way to improve in the long run.
That was my point, exactly.
Plus a little bit of frustration.
