It does not seem possible, but he could be.
Cheater?

why not? i am not a procedural player. just play as it comes. don't know what moves are called. but sometimes it clicks awesome. sometimes i fail miserably. same could be true with him!

btw, from what I have seen.. players around 1200 or above in bullet chess are usually very good. My ratings have swung all the way from 1150 to 900

@FirebrandX - At the end I did that move because I didn't see other ways. There were alternatives?
@All - Thank for your opinion. I remind you my opponent did all you see in 2:30. After your answers my personal opinion remains the same: probably cheater. FirebrandX, I know we both played bad, but he did some moves that I never see from players of his rating (I play often with ones of that rating, so I know what i'm talking about... maybe I'm wrong, but probably not...).
Is it possible someone with 1276 lighting ELO plays like this?
Oh, did I specify he did all this in 2:30?
