intersting for strategical reasons. Whites setup is in a way quite logical.
The Maroczy-setup with Ps on e4 and c4 - with control over d5 - gives him a
certain space-advantage. Now it is well-known that the player with more space
should avoid exchanges - so 7. Nd4-c2 is in a way logical. However after
retreating his central placed N white wastes a tempo and gives black time to
break down the strong white pawn-chain f3-e4 by attacking Pe4 with Nc5 and Pf5.
According to theory black has no special problems. How can it be then that one
of the greatest experts on the black side of the Maroczy loses this game?} 13.

{This game was played in round 11, when I was on "plus one" and had been just
back in a winning streak after a disastrous start. Hammer was not performing
at his best in the tournament either. So, in general I felt quite confident
before the game.} 1. Nf3 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 c5 5. d4 cxd4 6. Nxd4 {
This position with the Maroczy structure is usually seen via another opening:
the Accelerated Dragon in the Sicilian.} Nc6 7. Nc2 {It makes sense for White
to avoid exchanging some pieces, as he has a space advantage and a more
pleasant life. But, on the other hand, he loses several tempi moving his
knight to a less active square.} (7. Be3 {is the main line.}) 7... O-O 8. Be2
d6 9. O-O a6 {So far everything looks normal for this kind of position. White
controls the centre, while Black tries to undermine it. Now both sides
manoeuvre with their pieces.} 10. Be3 Rb8 {Preparing ...b5 at an appropriate
moment. Usually Black needs to play Qa5 to support the b5-break.} 11. f3 {
Defending e4 in advance, thus increasing the pressure on the b5-square.} Be6
12. Qd2 Nd7 13. Rab1 {Preventing ...Qa5. White is now ready to start
activities on the queenside. Black can not play ...b5, so the only logical
counterplay is to go for ...f5} f5 14. exf5 Bxf5 15. Rbc1 {The rook has
nothing to do on b1 now, so White changes his plan.} ({Less accurate is} 15.
Rbd1 {because of} Qa5 16. Nd4 Nxd4 17. Bxd4 Bxd4+ 18. Qxd4 Qc5 {The endgame is
OK for Black.}) 15... Qa5 16. Qd5+ (16. b4 $1 {is stronger:} Qe5 17. Nd5 Bxc2 (

20. Bd3 $14 {White is better thanks to his bishop pair and space advantage.
Black's pawn structure is more weakened as well.}) 16... Kh8 {After some time
considering this move and 16...Rf7, I preferred this one.} (16... Qxd5 17. cxd5
Nce5 18. Nd4 Rfc8 19. Rfd1 Nf6 {The computer says this is equal, but during
the game I thought it would be unpleasant to play for Black. Practically
speaking, it is much easier to play with White here.}) ({I was very unsure
about} 16... Rf7 17. Qxa5 Nxa5 18. Nd4 Nc6 19. Nxf5 {, when Black has to
recapture with his rook} Rxf5 (19... gxf5 20. c5) 20. Rfd1 {and to me it looks
better for White.}) 17. Qxa5 Nxa5 18. Nd4 Nc6 19. Nxf5 gxf5 {My idea was to
take with the pawn, in order to gain some space. In this position if White can
manage to play f4 and preserve his bishop pair, then he definitely stands
better. However, unfortunately for White, he does not have enough time for
that. That's why I went for Kh8 instead of Rf7.} 20. Rfd1 (20. f4 Bd4 21. Bxd4+
Nxd4 22. Rfd1 e5 {looks fine for Black.}) 20... f4 21. Bf2 Nc5 {Following the
tempting plan to exchange the bishops.} 22. b3 Ne6 23. Bd3 Bd4 24. Be4 Bxf2+
25. Kxf2 Nc5 {Objectively speaking, White must be slightly better here. Black
has achieved his aim - to exchange the bishops, but White's remaining bishop
is still strong. Black's pawns on f4 and e7 are a little bit vulnerable as
well.} 26. Bd5 $6 {The bishop stands very nicely here, but it creates no
threat.} (26. Bb1 $5 {deserves attention, with the idea to leave d5-square for
the knight. Then White can play g4 (or g3) to open the kingside if he wishes.})
26... Nb4 27. Ke2 $6 {This move is really strange. White's king should just go
back to g1 or f1, leaving the e- and d-files for the rooks.} Rf5 28. Rd2 Rh5
29. Kf1 $6 {I did not understand why my opponent sacrificed the pawn for
nothing - while he could keep it. Of course this inaccuracy does not make
White losing, but it eliminates White's winning chances. Now he has to fight
for a draw.} (29. h3 Re5+ {Black is probably not worse anymore, since he
provokes some weaknesses for White as well. But for sure with such a solid
position, White can not be worse either.}) 29... Rxh2 30. Kg1 Rh6 (30... Rh5 {
is not correct because of} 31. Re1 Re5 32. Rxe5 dxe5 33. Ne4 {with an
approximately equal position.}) 31. Re1 e5 (31... e6 32. Be4 e5 33. Red1 Rd8
34. Kf2 {White has compensation to maintain the balance, but not more.}) 32.
Red1 Rd8 33. Ne4 Nxd5 34. Nxc5 $2 ({Correct is} 34. Rxd5 Nxe4 35. fxe4 Rg6 36.
Kf1 Rc8 37. Rxd6 b5 {, when it seems to be very drawish.}) 34... Ne3 35. Re1 $2
({White's only defence is} 35. Nxb7 Rd7 36. Nc5 Rg7 37. Ne4 Rhg6 38. Rc1 {
, where there are some drawing chances left.}) 35... b5 $1 36. cxb5 axb5 $17 {
Now Black is just a healthy pawn up. Moreover, the attack on the kingside
still exists.} 37. Nd3 Rg8 38. Nb4 Nf5 39. Rc1 Nd4 {With huge pressure on the
board and on the clock, my opponent failed to make the time control. The final
position is probably already lost. With this win I scored "plus two" the first
time in the tournament, and managed to keep that till the end.} 0-1
