1. d4 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. h3 O-O 6. Bg5 {Aronian quickly
played this move. Maybe sensing that Hikaru was out for blood, the Armenian
prepared something against Nakamura's King's Indian Defence.} c5 {The most
common reply, transposing back into Benoni waters.} 7. d5 a6 8. Bd3 $5 (8. a4 {
preventing b5 is by far the most common idea. Levon has the notion that the b5
advance is not dangerous in itself, and White can allow it as long as he
obtains quick development.}) 8... b5 9. Nf3 Nbd7 10. O-O h6 {This move isn't
something black wants to play as it is a weakness and it makes the e6 break
harder as a swap of pawns on that square will severely weaken g6. However the
bishop on the g5-d8 diagonal can prove to be very annoying.} (10... b4 {
closing the queenside is always possible, but never desirable.} 11. Ne2 a5 12.
Re1 $14 {and White will slowly but surely work on getting the e5 break in.})
11. Be3 bxc4 12. Bxc4 a5 13. a4 Nb6 14. Bd3 Ne8 $5 {A typical maneouver in the
Benko Gambit - which is very similar to the position on the board. If someone
asked an experienced grandmaster which opening this position originated from,
a b6 Benko is definitely one of the possible answers.} 15. Re1 Nc7 16. Rc1 Na6
$6 {The knight marches towards b4, its perfect outpost - though it is possible
that on c7 the knight was already well placed as it controlled b5 and allowed
Black to take on e6 with the knight.} (16... Ba6 $1 {It is known that
exchanging bishops is good for Black in these setups.} 17. Bb1 $2 (17. b3 Bxd3

{This is just asking for trouble.} (20... h5 21. Ng5 $5 Bb2 $6 (21... Nd7 $1 {
regrouping the knight, is far more solid and to the point}) 22. Nf4 {gives
White a huge initiative with sacrifice possibilities; however maybe Black can
somehow complicate the issue.}) 21. h5 cxb3 22. Qxb3 {White's plan is very
simple: attack on Black's weakened lightsquares on the kingside.} g5 23. Ng3 {
Obviously the knight is headed to f5. Black cannot allow this, once the knight
gets there the game is over as the pressure would become unbearable.} N6xd5 {
Desperation. Aronian from now on sweeps the game without any issues.} 24. exd5
Bxd5 25. Rxc8 Bxb3 26. Rxd8 Rxd8 27. Nf5 {If Black had time to regoup, to take
a4, and maybe set up his pawns on e6 and d5 he would be ok, but that's not
going to happen.} Bf8 28. Bb6 Rb8 29. Bc7 Rc8 {Nakamura plays in the most
cunning way, always placing his opponent little traps that he might fall for.
The game isn't won just yet, but it is a huge advantage for White.} 30. Bxa5 (
30. Nxe7+ Bxe7 31. Rxe7 Nd5 {and suddenly it is White who is against the ropes.
}) 30... Nc6 31. Bc3 Bxa4 32. Ba2 Rc7 33. Nh2 $6 (33. Ne3 {was another
interesting regrouping, probably stronger than the one in the game. Aronian is
focused on the h6-pawn though.}) 33... Ne5 $1 {Probably the best practical
chance. Nakamura will try to defend a position in which he is down a piece for
a pawn, but he will have a solid pawn structure and will simply try to build
an impenetrable position.} 34. Bxe5 dxe5 35. Ng4 e6 36. Ng3 (36. Nfxh6+ Kg7 37.

the reduced amount of material might give Black some hope.}) 37... Rc1+ 38. Kh2
Bd6 {is Hikaru's "point".}) 36... Kg7 37. Nxe5 Ba3 {The issue for Aronian now
is to create a clear plan of making progress. The pawns are creating a perfect
barrier against the knights, so its likely that a sacrifice at some point will
be necessary.} 38. Ne4 Rc2 39. Bb1 Rc1 40. Rxc1 Bxc1 41. Nd6 $1 {Forcing the
f-pawn to advance is a key part of this endgame. With this weakness it becomes
hard for Black to hold his kingside.} f5 42. Ndc4 Bf4 43. Nd3 $1 {The easiest
solution. Aronian shows remarkable technique.} Be8 44. Nxf4 gxf4 45. g3 fxg3

Bd1 Kf6 53. Bf3 Ba4 54. Bc6 Bd1 55. Bd7 $1 {Beautiful. It is the transfer of
the bishop to d7 that will win the game thanks to a clever set of zugzwangs
and knight maneouvers.} Be2 56. Ba4 $1 {At the right time. The bishop comes
back to b3 when Black doesn't have the time to protect h5 and bring his bishop
to e8.} Ke7 57. Bb3 Kd6 (57... Kf6 58. Bc4 Bd1 59. Nd7+ Ke7 60. Nc5 {loses
immediately.}) 58. Kg3 $6 {Transfering the king is slow and clumsy, much

move because of Kh5.} Ke7 60. Bb5 Kd6 61. Bc6 $1 Ke7 62. Bf3 $1 {with a
winning advantage.}) 58... Bh5 59. Kf2 Bg4 $2 {Returning the favor} (59... Be8
