So many blunders and still victory...

I did 9 mistakes, 8 blunders and still got a win by mating my opponent.
Ok it's a 3min game and I'm barely 1900.
Can this happen to 2000+ players?

I did not realize that 1900 players could play so poorly. This game looks like a noob fest. Wow!

Yep, very easily, and without blunder repetition you got in that game. It's mostly about time, definitely about style, and only slightly about strength. For example:

Indeed, I'm surprised myself too!

IMO, real chess starts from 2000+.

You made a lot of blunders in the opening, because you did not found out opponent's blunders. You did not find move Nxf3+ at all, that's the reason why you made so many blunders.

@FastMate When you get to 2000, you'll realise that real chess starts at about 2400. And if you get to 2400...

real chess???
So, i'm living a fake chess life in 1500, OMG!!!

Yes, sry, I should use the word "serious" :)

Mistakes... blunders.... but you know what? You should never give up.., even if your opponent is stronger than you are and you blunder a piece on move 6:

Typical 'bluffing' game
