Carlsen Takes Early Lean in Baden-Baden

The world champion Magnus Carlsen took an early lead at the Grenke Super tournament after defeating Michael Adams in a typical, positional style. Mickey was Magnus'second at the recent WC match in Sochi, which did not prevent the Norwegian from surprising him in the opening. The novelty promised Carlsen slight, but durable positional advantage:

move in the game scoes better for White, at least by percentage.}) 5... Bc5 6.

fact this is the actual novelty in comparison to the game Kiselev-Garakov from

Gd2e3,Ga1f1,Gf1f7,Gb1b7] The situation had changed. The doubled d pawn is gone
and the black b and d pawns were separated, thus they became clear targets. On
the other hand, the white bishop is seemingly not the greatest piece ever, but
so is his counterpart. White keeps pressure thanks to the fact that his
heavy pieces are more active and exert pressure. They are actively assisted by
the "poor" bishop that effectively shuts both the a and e semi-open files for
Black.} (24... d5 $4 {is positionally sound but tactically wrong} 25. Bb4) 25.

Now the bishop can be actively used on the h4-d8 diagonal. Magnus also intends
to further advance the pawns on the kingside and open the game there. Thus, he
will create one more weakness- the black king and thanks to the extra space he
can be much more effective in maneuvering on both sides of the board.} Re4 32.
