Carlsen is different. Of course he knows the openings, but he knows them in a different way.... And he can see the flaws, ... that you don't play so well in quiet positions with Rooks and Bishops of opposite color, or that you tend to resolve pawn tension prematurely on the side you castled.
Carlsen's preparation, then, is more like Lasker's. He isn't going to wow the crowd with TNs in the openings so much, but he manages to get people into positions they are less comfortable with, where he has some chances to make them squirm.
Very interesting. I haven't heard this before -- that Carlsen's preparation for his opponents is targeted not towards openings or specific positions that they don't play well but towards types of positions they play less well. Do you have a source for this, or is the hypothesis based on your own analysis?
Carlsen is lazy, just like the young Karpov was. He's almost like Karpov reincarnated, in terms of his lack of opening prep/knowledge.
