Surprises in round 2

Anton Filippov defeated Etienne Bacrot grinding him down in an ending that should probably be holdable. It isn't 100% clear to me where things (probably 45...g6?) went wrong but things went down hill fast from the diagram.

(44... g5+ 45. Ke4 Ke6 46. Bg4+ Kf7 is maybe best.)

45. h4 g6?

Dennis Monokroussos of Chess Mind has looked at this game and mentions to me that he thinks this is the losing error "I didn’t blog the game, but spent some time analyzing it and the best I could find was a line where White, by eventually playing h5, e6 and e5, could win the c6-pawn" but he still thinks it is drawn. Konstantin Landa didn't like 45...g6 either in commentary.

Zoltan Almasi played some rather rocky chess at the Olympiad proving rather prone to going astray in well played games. Today here he had a satisfactory position against Mircea-Emilian Parligras but then went wrong. Although later his opponent didn't play the best he could not recover.

Francisco Vallejo Pons blew winning chances against Lazaro Bruzon Batista (not completely straight forward but nevertheless a GM should be able to find them) and playing on through inertia even went on to lose. It is hard to see him recovering from that.

Surprise winners from Round 1 lose in round 2

Alexander Morozevich completely outclassed Alexandr Fier (surprising winner against Wang Yue in Round 1) on the black side of a French. Fier never got anything going after the opening and Morozevich just straightforwardly broke through on the queenside.

Yaroslav Zherebukh (also a surprise winner in round one eliminating Eljanov) beat Ruben Felgaer who surprised Malakhov. Today Felgaer played three bad or dubious moves in a row and his position just fell apart from being almost equal.

Some other winners in Round 2

Three of the more interesting games were extracted from this article to A separate article on opening disasters they were Gashimov's win against Sergei Azarov, Nikita Vitiugov's win against Anton Korobov and Vladimir Potkin's win against Alexei Shirov.

Emil Sutovsky gradually outplayed Laurent Fressinet in an interesting Ruy Lopez Berlin Defence.

Teimour Radjabov gradually outplayed Parimarjan Negi winning in 42 moves.

Viktor Bologan lost a complex struggle as white with Leinier Dominguez Perez with white.

Vassily Ivanchuk kept setting Evgeny Alekseev problems in an ending that should be drawn and eventually was rewarded with a win in 97 moves.

The Draws

Top seed Sergey Karjakin didn't make any progress against Wesley So's French Defence.

Ruslan Ponomariov equalised against Ni Hua very quickly and the game was agreed drawn in 12 moves in about 30 minutes.

Yuri Drozdovskij was involved in a lengthy playoff against Alexander Motylev in round 1 and so took a quick draw against Ni Hua with white probably just to give himself a free day to rest.

Rustam Kasimdzhanov took a quick draw with white against Gata Kamsky after around 45 minutes play of an exchange Gruenfeld.

Alexander Grischuk as usual spent a lot of time in the opening. First of all with 8...Re8 and then on his move 11. He was in a small amount of trouble but held on against Sebastian Feller.

Sam Shankland earned a quick 15 move draw on the black side of a Slav against Abhijeet Gupta when he probably did a little better than equalise.

Peter Heine Nielsen managed to quickly equalise on the black side of the Sicilian Dragon against Michael Adams and after 1 hour 45 minutes and 23 moves of play the game was drawn.

Nguyen Ngoc Truong Son drew very comfortably with black against Peter Svidler playing 3...h6 against Svidler's Tarrasch French Variation.

There were only two women playing in this event. Sergei Movsesian plays both of them in the first two rounds. He beat Women's World Champion Hou Yifan in Round 1 and now plays Women's World Number one Judit Polgar in Round 2. Game one was a fairly dull draw that traded into a level ending that was agreed drawn in 32 moves.

Play the Queen's Gambit

Shakhriyar Mamedyarov was held by Daniel Fridman, an expert in the Queen's Gambit. They followed a variation Fridman won with in Round 1. Fridman wasn't too happy with his play later in the game but he demonstrated some of the ideas of the variation on commentary afterwards. His position was strong enough to hold the game even if he wasn't completely happy.
