The 7th Round of the 4th Final Masters saw the leader Vassily Ivanchuk defeated for the second time. Francisco Vallejo Pons played well to win a complex English Opening against Ivanchuk in a game that was settled in a time scramble. Ivanchuk's lead was only cut by a point as the other games were drawn. Levon Aronian's 9.h4 in the Queen's Gambit is a very old Botvinnik idea which led to a very difficult position for both players. Carlsen looked to get the upper hand after a nice combination but Aronian steered the game into a drawn ending. Hikaru Nakamura easily held World Champion with black in a dry theoretical battle in a Ruy Lopez Berlin. Round 7 Standings: Ivanchuk 13, Carlsen, Nakamura, Anand Aronian 8 Vallejo 7. Round 8 Pairings: Ivanchuk-Anand, Carlsen-Vallejo and Nakamura-Aronian.

Francisco Vallejo Pons 1-0 Vassily Ivanchuk

Francisco Vallejo Pons played his best game of the event so far in beating runaway leader Vassily Ivanchuk. This English opening seemed to be a hybrid of systems including the Gruenfeld. Also the position has been played without Vallejo's 5.h4 and Ivanchuk's 6...h6. Both players seemed to be working things out themselves from early on and by move 22 they were both short of time. It may be the Ivanchuk lost because he felt he was better, it is hard to believe he would have lost if he had played 21...Qd8 but instead Ivanchuk had to be careful not to get mated and in avoiding that problem was forced into a lost Rook and Pawn ending that Vallejo made no mistake in converting.

Levon Aronian draw Magnus Carlsen

Levon Aronian went back to 1944 and played an extremely aggressive idea from Mikhail Botvinnik which doesn't seem to have been tried at any kind of high level since. 9.h4 introduced all sorts of vicious attacking ideas based on Ng5 or g4 but also weakens g4 and white's king's position in general. Carlsen's 9...c5 struck back at the centre at the cost of a pawn and I imagine both players were on their own resources pretty soon after that. Aronian's 13.Nxd5 was maybe not the only choice in that position, and his 16.Rc7 seems to have been an error which allowed Carlsen to take the initiative. Aronian however calculated precisely and by move 27 the game was drawish a fact Carlsen recognised by trading rooks on move 30. Maybe we'll see 9.h4 tried in a few games, it certainly looks interesting, but computers may suck the fun out of it pretty quickly.

It looks like it is black that should be in danger here but this position is really complicated.

Anand draw Nakamura

We can only hope that deep preparation doesn't make all elite chess like this, because then there won't be any. Nakamura thanked Kramnik afterwards on Twitter for his deep preparation work in making this an off the shelf drawing weapon. 21.Kf2 was the start of the game according to Nakamura and his suggestion of 31.f4 for Anand didn't change the assessment of equal. They drew after 36 moves.

Thanks to Kramnik I was able to just play something silly like the Berlin and draw against the World Champion relatively effortlessly.
