Turning an explosive Latvian Cloud into a slow, grinding game

Karpov-Dnotchelly 1978, Casual Game. 

Karpov employs the Bongcloud. Dnotchelly counters with the shaky Latvian Cloud, and Karpov artfully transforms it into a blocked, slow game. Dnotchelly gets frustrated and tries to break through, allow Karpov to use his far superior king development to clear off the queenside and march down his king there. 

great game but a few mistakes from white at the end there cost you a much easier win

I didn't play White, Karpov did...

Could you point out the mistakes? 

Is this a joke?

lol

edit: after ke3 I knew for sure it was a joke L

Excuse me? 

Could you please respect the openings of others? How would you like it if I laughed at the Ruy Lopez or the Sicillian? 

haha. Lol..

What?
