Last year Komodo won the world championship title on two occasions and can call itself â€œ2019 World Computer Chess Championâ€ and â€œ2019 World Chess Software Championâ€. And the current Komodo 14 has been clearly improved over its predecessor!

1/20/2015 – Another round full of drama today. Aronian wiped Jobava off the board in 24 moves, Carlsen outplayed Radjabov to extend his lead since So drew MVL. Also Carlsen reaches six wins in a row! Giri climbs positions by defeating Ding Liren. However, the most exciting game of the round was a draw between Caruana and Hou Yifan, where the Women's World Champ missed a beautiful opportunity.

The Tata Steel Chess Tournament has two main tournaments. They are played according to the 'round robin' system, whereby each competitor plays in turn against every other during the tournament. The Tata Steel Masters has 14 participants and the Tata Steel Challengers has 14 participants. Both groups start on January 10th 2015 and the last round is on January 25th. All rounds in Wijk aan Zee begin at 13.30 hours, except for the last round on January 25th, which begins at 12.00 hours. The time control is 100 minutes for 40 moves, followed by 50 minutes for 20 moves, then 15 minutes for the remaining moves with 30 seconds cumulative increment for each move starting from the first move.

Admission to the playing hall in Wijk aan Zee, Rotterdam and The Hague is free of charge

Aronian, Levon 1-0 Jobava, Baadur

Jobava played rather creatively, but his kingside was far too weak. Aronian walked all of his pieces over to that side of the board and smashed Jobava's position:

Levon Aronian with a much needed win

[Event "77th Tata Steel GpA"] [Site "Wijk aan Zee NED"] [Date "2015.01.20"] [Round "9"] [White "Aronian, L."] [Black "Jobava, Ba"] [Result "1-0"] [ECO "A56"] [WhiteElo "2797"] [BlackElo "2727"] [PlyCount "47"] [EventDate "2015.01.09"] 1. d4 Nf6 2. c4 c5 3. d5 g6 {Even though this move has been played thousands of times, it is irregular.

Bb1 b6 13. O-O Ba6 14. Nb5 h6 15. Bc1 {Black's position is already difficult. He has no space, which means it is difficult for his queenside to connect with his kingside.} Bxb5 16. axb5 Ne8 17.

Bxg6 {is completely crushing.}) 1-0

Wojtaszek, Radoslaw ½-½ Ivanchuk, Vassily

Ivanchuk put his own spin in a variation that is becoming increasingly popular. He equalized and the position became locked at some point, with both players finding difficulties improving their position. Ivanchuk broke the center with ...f6, but it seemed to give White some play. The final position seemed a little more pleasant for White, maybe considerably more pleasant.

Ivanchuk has let off the gas in the last few rounds, but he is still in the top positions (behind Carlsen)

So, Wesley ½-½ Vachier-Lagrave, Maxime

A pawn sacrifice in a Grunfeld (does Black always sacrifice a pawn in the Grunfeld? It increasingly looks like it) left MVL down a pawn but with plenty of compensation. So blundered with the move 28.Re7, missing his opponent's reply. However in time pressure MVL was not able to use his passed a-pawn and powerful bishop, and the game fizzled into a draw.

MVL's arsenal. He likes to skip lunch, so chocolate gives him energy during the game.

Carlsen, Magnus 1-0 Radjabov, Teimour

Carlsen convincingly outplayed Radjabov:

This duel was one sided in favor of Norway

Caruana, Fabiano ½-½ Hou Yifan

What an exciting game! Both in time pressure and after the time control was reached. Hou Yifan missed a brilliant chance against Caruana:

Giri, Anish 1-0 Ding Liren

Giri played a fantastic game against Ding Liren's King's Indian Defense. He beat back the attack with precise and powerful moves. His winning advantage was almost enough for Ding Liren to resign, but the Chinese fought on and Giri's technique was certainly lackluster. He made it very hard on himself, but eventually converted.

Ding Liren tried very hard to save a hopeless situation

Giri started out playing amazing today, and although

his finish was not the best he still wrapped up the full point

Saric, Ivan ½-½ Van Wely

Van Wely played the Pirc, an unusual guest in these types of tournaments. Saric obtained a nearly decisive advantage in the queenless middlegame, obtaining an extra pawn and retaining the superior piece placement. He, however, completely underestimated Van Wely's counterplay. Saric kept digging his own grave, until eventually Van Wely reached a winning rook endgame... that he blundered away:

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. "
