this position several times, although only twice have my opponents gone for
this modest move.} (6. Nc3 Nbd7 7. e4 Bxf3 8. gxf3 e5 9. Be3 {is, in my
opinion, the most testing line.}) 6... Nbd7 7. g3 Bh5 8. Bg2 e6 9. O-O Be7 10.

went for this plan (the first time was against Sergio Cacho, at the Spanish
Championship in 2009). Black wants to play on the queenside, and to that end
he needs to play ...b5 and ...c5. Therefore, it seems very logical to me to
put the rooks on c8 and b8 and bring the queen back home. On d8 it doesn't get
in the way, and in some lines it might go to f8, putting pressure on a3.
White's position is "nice", but it's hard to come up with a clear plan. In
both games I got a fantastic position, but unfortunately my play later on left
much to be desired.} 14. e4 Qd8 15. h3 b5 16. Qd3 Rab8 17. Qe3 c5 {Black can't
complain. He has managed to accomplish his aims and White hasn't really done
anything.} 18. Rec1 Bg6 {There is no need to hurry, so I improve my bishop.
The pressure on e4 is quite annoying.} 19. Qe2 a4 $1 {Good timing. All my
pieces are perfectly placed, so it's time to open up the queenside. After the
game, Georgiev admitted that at this point he wasn't happy with his position
at all.} 20. dxc5 (20. Ne5 axb3 21. Nxg6 hxg6 22. Nxb3 c4 23. Nd2 Nb6 {[%cal

Generally speaking, a very good game. After the mistaken 10.b4 my opponent had
to play very accurately to survive (the position is more critical for her than
it seems), and did so with flying colours, reaching a roughly equal ending. In
time trouble however, two serious mistakes brought down her position. After
the time control we reached a very complex position, which is nearly
impossible to play over the board, and despite some mistakes I think we both
handled it quite well. Actually my opponent was pretty unlucky that 46.Bxc3
isn't good considering how natural it is. This important victory gave me the
momentum to win my next two games, but two draws and a loss put me in a bad
situation after round six. However, Braun's complete collapse of four (!!)
consecutive losses brought him from clear first place to the middle of the
pack. The going still wasn't easy but a strong final sprint (wins against
Ushenina, Nijboer and Negi) brought me clear first place.} 0-1

{I will not hide that I waited with impatience and curiosity for the moment
when Carlsen would step in. Fortunately, the reigning World Champion does not
seem to have lost any single bit of his interest for the game after reaching
unprecedented rating heights and conquering the supreme title at all the
official time rates (classical, rapid and blitz). Maintaining the flame of
enthusiasm alive when there is no higher level to aim at is a task not many
World Champions have dealt with sucessfully. Anyway, since his presence in the
team surely makes a big difference, Carlsen was ready for the fight as soon as
round two.} 1. d4 d5 2. c4 c6 3. Nf3 Nf6 {An interesting choice of the opening.
Carlsen has played the Slav in the past, but it is by far not his main weapon.
The puzzling thing is that in a game where the big rating difference strongly
required him to play for a win, he exposes himself to a transposition to the
symmetrical structure resulting after 4.cxd5 cxd5. The Exchange Variation is
not as dull as it seems and players like Botvinnik or Portisch have made good
use of it with white, but Black has his reasons for being content, too.
Objectively, he should be close to equalising, which actually is just one
preliminary step on the way towards taking over the initiative.} 4. Qc2 {
(!) Played almost without hesitation. I assume that Tomi was not really
bothered by the idea of a draw (although I may be wrong), but even though the
exchange variation makes up part of his repertoire, he does not show himself
ready for such early relasing of the tension.} dxc4 5. Qxc4 Bg4 {This has

decisions regarding his king safety.} 16. Kc2 {the computer's first choice.} (
