What is your favorite chess player? with reason.

Petrosian: So difficult to beat.  The only player to go 2 years in a row without losing in the USSR championship.  The master of the exchange sac, and his motto of safety above all else. 

Capablanca: No one has made the game seem more simpler, and his end game play is the best.

Karpov: Was not a fan in my younger years, but have grown to appreciate his mastery of the game.  His "Boa Contrictor" style is beautiful.

Yes, he has indeed played it in a couple of blitz games and against Gustafsson, but that doesn't really make it a Kramnik opening in the way it has been for players like Fischer, Kasparov or Radjabov.

That game shows a Pirc, not a King's Indian Defence.

In non-Classical Kramnik did play the KID against Gelfand in Amber 2010 (and lost). Before that he had only played it in Las Palmas 1996 and Tilburg 1997, with bad results also back then.

Now this is what I call a KID player, already a career total of +56-45=96 with the opening as black before turning 28:
