Bg7 6. Bd2 O-O 7. g3 c5 {I'm not a big fan of this move here. For one thing, this is not a developing move. If you look at the similar position with reversed colors, Black is doing quite well with this Bd7 and Qc8 thing, and here with an extra tempo White can really cause problems for the black king.} ({Both} 7... Nc6 8. Bg2 Nb6) ({and} 7... e5 8. Bg2 Ne7 {seem more suitable to meet White's h2-h4 offensive.}) 8. h4 $1 { [#] Officially, a novelty. I mentioned in my previous reports how Aronian's opening preparation blends with his style of play. Levon seems to be getting his kind of positions nearly every time he has White.} Nc6 ({Surrendering the g5-square is unpleasant:} 8... h5 9. Bg2 Nc6 10. Ng5 Nc7 {and now White can even try} 11.

At least, he's well mobilized, as seen from a sample line} 11. Be3 Rc8 $1 12. Bxc5 Bxf3 13. Bxf3 Ne5) 9. h5 Nxc3 ({I wonder if Black can get away with} 9... b6 10. hxg6 hxg6 11. Bg2 (11. Qa4 Nd4) 11... Bb7 12. Ne4 Nd4 13. Nxd4 cxd4 {or some such play.}) 10. bxc3 c4 $1 {An interesting concept from Anish. Too bad he didn't follow through on his ideas a couple of moves later.} 11. hxg6 hxg6 12. Qa4 {Aronian is very good in setting his opponents up with positional riddles.} ({The immediate} 12. d4 {allows Black to strike in the center with} e5 {and there's d4-d5 in reply to it.}) 12... Na5 $2 {That's exactly what Levon hoped to see.} ({The principled reply} 12... cxd3 {was most likely turned down because of} 13. Qh4 {Indeed, this had to be the idea behind White's previous move. It takes a lot of nerve to dismiss the other guy's ideas when he happens to be the World's #2. Still,} f6 $1 {[#] was fully playable. Nevermind the danger to the king: we're destroying White's center! The most direct attacking line,} 14. Bh6 (14. exd3 {meets with} Kf7 $1 {and Black is ready to intrercept the h-file, while his light-squared bishop covers the king from e6. You know what? White may be worse here.}) 14... Qa5 15.

Qb2 Re7 {It looks like Black has a lot of compensation for a pawn.}) 13. d4 $1 {Now, as the black knight moved away from the center, Aronian stakes his claim in the middle of the board.} b6 14. Bg2 Bb7 15. Qc2 {If Black could only have his c-pawn back on c5, he would have had a normal Grunfeld. As it is, he has no counterplay to speak of.} Qd5 16. Nh4 Qd7 17. e4 e5 18. d5 Bc8 {Giri just cleared the b7-square for his knight, but he won't be given the time to complete his maneuvering.} 19. f4 $1 Qe7 (19... exf4 20. gxf4 Nb7 21. Be3 $1 Nc5 22.

Rg4 $6 {This is the one and only slip-up from Aronian in this brilliant game.} ({The somewhat counter-intuitive} 24. Qg4 $1 {would wrap it up soon:} Bf6 25. Rh7 Ke8 26. Bh6 Nb7 (26... Kd7 27.
