1. Nf3 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 {This is the variation which is
known as the Anti-Grьnfeld. Despite being a Grьnfeld player for many years, I
didn't like the black side of the Anti-Grьnfeld. But recently, following the
games of Sutovsky I have found it quite reliable . Usually I meet 1 Nf3 with 1.

Alexander has won a huge number of brilliant games.} 5. g3 ({White has two

1. d4 Nf6 2. c4 g6 3. g3 c6 {The fianchetto variation against the Grьnfeld has
started to gain an excellent reputation. White is scoring pretty well against
Black's attempts of playing a direct d5. Hence, the lines with c6 followed by
d5 are becoming increasingly popular.} 4. Bg2 d5 5. e3 {When Kramnik played
this move against Gelfand in London Candidates 2013, Krasenkow who annotated
the game for ChessBase Magazine wrote, "No theory, Just play!" This is not the
case anymore. Games are being played in this system quite often and White is
scoring pretty well.} dxc4 {This should be real test of White's idea. Black
grabs the pawn and asks White, "How exactly are you planning to regain the
pawn?"} (5... Bg7 6. Ne2 O-O 7. O-O {is the other important position of the
opening. Black players have played literally every logical move here starting
from b6, e6, dxc4, Nbd7 and many more.}) 6. Nd2 ({The game Kramnik-Gelfand
continued} 6. Ne2 Bg7 7. O-O O-O 8. Na3 Nbd7 9. Nxc4 Nb6 10. Na5 (10. b3 {

the long diagonals.}) 10... Qc7 11. b4 e5 $11 {when Black had equalised.}) 6...
Be6 $146 {Not surrendering the pawn so easily. This is already a novelty but
surely one of the most logical moves in the position.} 7. Ne2 {The knight
threatens to go to f4.} (7. Qc2 {trying to recover the pawn is met with} Na6 $1

the white knights!} 11. a3 (11. dxe5 $2 b5 $19) 11... b5 12. axb4 Bxc4 $13 {
with an unclear position where Black's chances do not look even one bit worse.}

get back his pawn.} 9. O-O (9. a4 $5 {should have been considered by
Mamedyarov.} Nbd7 10. Bxc6 (10. axb5 cxb5 11. Bxa8 $2 {taking the exchange
would be completely wrong as the light squares would be horribly weakened.}

11. Bg2 (11. Nxc4 Rc8 $36) 11... Rc8 $13 {with a complex position.}) 9... O-O
10. b3 $1 {Of course this idea is quite common and gives White excellent
compensation down the a- and c-files. This same idea was used in the very high
profile game between Kramnik and Giri from the Qatar Masters 2014. That
occurred from a Slav Defence though.} cxb3 11. axb3 a5 {The c6-pawn is weak
down the c-file, Black tries to not be saddled with another one on the a-file.}
12. e4 {Somehow this does not feel right. I think it would have been more in
the spirit of the position if White went about clamping down the c5-square.
But it is not so easy to achieve. For example} (12. Ne4 Nxe4 13. Bxe4 Qb6 14.
Bb2 Rc8 15. Rfc1 Nd7 $15 {Black has excellent development and is a pawn up.}) (
12. Nc3 {trying to reach the e4-square with a knight is sort of refuted by} Na6

square on d3 and White keeps good compensation in this case.}) 12... Na6 {
Giving back the pawn to complete his development. A very practical decision.} (
12... Qb6 {trying to keep his extra pawn came into consideration. And the
discovered attacks do not really work here.} 13. Nc4 $2 bxc4 14. Bxh6 cxb3 $17)
13. Qxc6 Bd7 14. Qc2 (14. Qb7 {It would have been better to keep the queen in
the thick of things. This causes some co-ordination issues for Black and the
threat of e4-e5 is not so easy to parry. Yet Black is fine after} Nb4 $1 15. e5
Nfd5 16. Bxd5 Rb8 $1 17. Qa7 Nxd5 18. Qxa5 Qxa5 19. Rxa5 $11 {with a balanced
game.}) 14... Nb4 {Slowly and steadily, black pieces start occupying active
squares.} 15. Qb1 Rc8 {A glance at the position reveals that Black is much
better co-ordinated. Even though White has a wonderful centre, his knights on
d2 and e2 do not paint a good picture.} 16. Nf3 Bxc1 17. Rxc1 Rxc1+ 18. Nxc1 (
18. Qxc1 Nxe4 $17) 18... Qc7 19. Ne1 Rc8 {Black has controlled the c-file and
the next plan is definitely to use his queenside pawn majority.} 20. Ncd3 $6 {
The position of the knight on b4 was the only thing that was preventing Black
from going a5-a4. This voluntary exchange of knights makes Black's task of
creating a queenside passer much easier.} Qc3 21. d5 (21. Nxb4 Qxb4 22. Qd1 $15
{was the lesser evil but there is not doubt that White stands worse.}) 21...
Nxd3 22. Nxd3 Qd4 {Making way for the rook to come into c3 and at the same
time eyeing the e4-pawn and the f2-square.} (22... a4 {was a simple and strong
move which could be made without any real calculations.} 23. bxa4 bxa4 $17 {
[%csl Ga4]}) 23. Ne1 (23. Rxa5 $6 Nxe4 $17) 23... Ng4 24. Ra2 Ne3 $6 {Navara
gets carried away and in a very promising position goes for a flashy
continuation that throws away all his advantage.} (24... a4 $1 $17 {was a much
more logical way to continue. With this move Black gets an outside passed pawn
and the pressure against his kingside remains. With activity on both the wings,
White's defensive task is anything but easy.}) 25. Qd3 $1 {Maybe this is what
Navara missed.} (25. fxe3 {Of course Mamedyarov was not going to take this
knight.} Qxe3+ 26. Kf1 Rc1 $19) 25... Qxd3 (25... Rc1 26. Qxe3 (26. Qxd4 Rxe1+
27. Bf1 Rxf1# $19) 26... Qxe3 27. fxe3 Rxe1+ 28. Kf2 $14 {and the a5-pawn
falls.}) 26. Nxd3 Nxg2 27. Kxg2 {White suddenly has excellent co-ordination
and his pieces are perfectly placed. All this happened just because of the
reckless 24...Ne3.} a4 (27... Rc3 28. Ne5 $14) 28. Ne5 Be8 29. bxa4 bxa4 30.
Nc6 {Defuses the position completely.} Bxc6 31. dxc6 Rxc6 32. Rxa4 {A very
close escape for Mamedyarov. White's opening idea of Nd2 followed by Qc2 and
b3 is interesting and worthy of closer investigation but White cannot really
hope for a serious edge as Navara's accurate play revealed.} 1/2-1/2
