1/23/2015 – While Carlsen drew and maintained his lead, Wesley So continues his superb run by beating Ivan Saric, and is now within a half point of the leader. Among the numerous exciting games, the one that stood out between Wojtaszek and Ding Liren, in which the Chinese player conjured up a fantastic win that no one saw coming. In the Challengers Wei Yi took the sole lead. Round eleven report.

Giri, Anish 1-0 Van Wely, Loek

An up and down, interesting game. Giri's attack was threatening and strong. Neither player figured out how to deal with the threats with precision, which gave us a very entertaining game:

Wojtaszek, Radoslaw 0-1 Ding Liren

A fantastically complicated game, and one of the most difficult ones for me to annotate in this tournament. It was simply too hard! The positions were always murky and both sides had an incredible number of resources. Wojtaszek bravely sacrificed a pawn, and Ding Liren did not react the best way. After reaching a winning endgame... Wojtaszek managed to lose it! To be fair, it was still very complicated, take a look!

Understanding the KID seems almost impossible, but Ding Liren manages to do it!

Carlsen, Magnus ½-½ Vachier-Lagrave, Maxime

A complicated Grunfeld landed the players in a weird endgame. Both sides' pair of bishops were the last remaining pieces on the board, but White managed to obtain an extra pawn. This was offset by Black's powerful passed a-pawn, always menacing. The game fizzled to a draw as both sides basically ran out of pawns to advance.

A fighting draw between the leaders

This brave, and somewhat suicidal, c-pawn is the reason the Grunfeld exists

Aronian, Levon ½-½ Ivanchuk, Vasil

Despite having a slight advantage from the opening, and always having some kind of pressure over the majority of the board, Aronian was unable to put Ivanchuk in serious difficulties. After running out of pawns on the queenside it was clear that his majority on the kingside would be insufficient to play for a win.

Levon Aronian, perhaps thinking back on his tournament

Caruana, Fabiano ½-½ Radjabov, Teimour

With 4.Nf3 and 5.g3 in the Nimzo-Indian Fabiano Caruana and Teimour Radjabov followed famous predecessors: In the first game of their 1985 match Garry Kasparov and Anatoly Karpov had this line on the board. Kasparov scored an impressive win and the previously obscure variation became famous. However, the game between Caruana and Radjabov was much less spectacular. After an early exchange of queens an equal endgame arose and after 41 moves the players settled for a draw.

Hou Yifan 1-0 Jobava, Baadur

Baadur fought hard to come back from an awful position in the opening. He was almost successful, but, as usual in this tournament, he ended up imploding.

Hou Yifan scores her first victory in Wijk aan Zee!

Well, at least this year, she won thrice last time she played here.

Nava now trails by half a point as he only managed a draw against Gunina.

Venues

The tournament has a slight change this year. Most of the rounds will be played in the traditional De Moriaan Community Centre in Wijk aan Zee, but two of the rounds will be played elsewhere. Last year the tournament traveled to the National Museum in Amsterdam and the High Tech Campus in Eindhoven.

This year the fifth round will be held in De Rotterdam. De Rotterdam is a building on the Wilhelminapier in Rotterdam, designed by Rem Koolhaas in 1998.

Rotterdam is ready to host Tata Steel!

The tenth round will be played in the International Press Cnetre Niewuspoort in the Hague. Councillor Karsten Klein of The Hague had this to say: "The Hague is honored to be able to host the Tata Steel Chess Tournament 2015 at the heart of the Dutch parliamentary democracy. Our city has a long history of international chess tournaments, a tradition which is continued in this manner. "
