All eyes were on only one game today, as if Aronian didn't lose this game the tournament would simply be over; no matter what happened in the other games, the tournament would be claimed by the Armenian superstar. That being said, the players themselves were fighting for those valuable Grand Chess Tour points and higher position in the standings. Don't forget, after all, there is a big pay difference between second and fifth!

The first result of round nine was, for many, rather predictable. Levon Aronian is known to be a magnificent defender and one that is sure to prepare his black sides to a dead equal position. He didn’t quite do that today, but he was very well-versed in the dubious variation of the Ragozin that Topalov employed, trying to catch him off-guard. Aronian even enjoyed a slightly better position but allowed his opponent to execute a perpetual check to end the game.

Topalov and Aronian played a game, but it was the Armenian calling the shots

2015 Sinquefield Cup winner Levon Aronian with Maurice Ashley


In the game between Anand and Carlsen, and much like their World Championship matches, the Norwegian decided to stick to his Berlin defense. Both players played rather slowly, perhaps unfamiliar with the variation. Anand mentioned looking at this variation in the past but could not recall the specifics. Carlsen was able to trade into an opposite-colored bishop position and draw the game.




Carlsen could have pressured Aronian had he not

lost to Grischuk, or blown his game against Nakamura!

Anand started slow and could not really recover


Vachier-Lagrave had perhaps a slight advantage against Giri after sacrificing a pawn, or at least that is what most grandmasters thought. The Dutch player himself thought that it was Black playing for the advantage! After a couple of careless moves from MVL, it was indeed Giri who was slightly better; unfortunately it was never anything special. The game dissolved into a drawn rook endgame.

Giri is just a bit too solid: eight draws!


Caruana had a crushing position against So basically from the opening. The engines were screaming that Black was basically lost, but Caruana kept giving So opportunities to get back into the game. At the end of the day, enough mistakes allowed So to solidify his position and hold onto a draw.

13...c7 is another possibility. 

14.h3 c7

14...a8 is what Karjakin has been playing lately, aiming for a quick b5. 

15.g4 a8 These players also took a long, long time to get to this position, despite being played in several high profile games. Topalov mentioned that he thought this idea of Qa8 was "basically losing". 16.d4 h6 17.g5 hxg5 18.xg5 e6 19.e3 Clearly something is wrong for Black. For starters, d6 is very hard to defend, and h7 being weak is annoying. b8 20.f4 f8

20...e5 offered more resistance if Caruana found the right way, but it looks positionally disastrous. 

21.xd6?

21.xd6! was already almost decisive. For example: xd6 22.xd6 White's up a pawn, but the tactics don't work for Black xc4 23.bxc4 xd6 24.h8+! The point. xh8 25.xf7+ g7 26.xd6+-

24...ce7 25.g2 xg2 26.xg2 h5 27.d5 Rx xe2 28.g4 d6 The position nis completely unclear.

The final game of the tournament was the duel between Nakamura and Grischuk. The American won more out of sheer willpower than anything else. Grischuk’s mistakes in the second time trouble gave Nakamura a winning attack. Even though he did not play the most precise moves, Nakamura was still able to take the point home.




Nakamura ground down Grischuk in a long game. He regains #2 in the World in the live ratings!
