Viswanathan Anand shares the lead with Hikaru Nakamura on 3/4 half a point clear of Levon Aronian, Anish Giri and Maxime Vachier-Lagrave going into the first rest day. Anand sacrificed a piece for huge compensation as his pawns proved too much for Wang Hao. Nakamura had to be at his defensive best to hold Giri in a game where both seemed to believe Giri missed some chances. Aronian brushed aside Ian Nepomniachtchi who just played a losing opening where he confused his move order. Vachier defeated Alexei Shirov in what looked like good preparation too. The remaining games were drawn.

Anish Giri made leader Hikaru Nakamura work hard for his draw in the final game of Round 4 to finish. Nakamura just about threaded his way through the complications to a drawn position. After the game both implied they believed white should be winning at some point.

Levon Aronian against Ian Nepomniachtchi. Photo © 2011 www.tatasteelchess.com.

Ian Nepomniachtchi was completely lost Levon Aronian after just 9 moves after confusing his move order in the opening. Nepomniachtchi's career has been delayed through ill-health according to interviews he gave around the time he won the Russian Championships and the suspicion is that his biggest weakness is the lack of a deeply prepared opening repertoire that is becoming essential to being a top professional. Aronian said afterwards that he doesn't make a habit of preparing for bad moves (9...Qb6) and he certainly didn't hang around in refuting it.

Played in a number of recent games.

8.Qxb7 cxd4?!

This may turn out to be dubious. The official video says he confused his move order in his preparation and so probably intended to play Qb6 here.

9.exd4 Qb6?

A move too late and black is already lost.

[9...Qd7 10.Qxd7 Nbxd7 11.c5 is miserable for black.]

10.Qxa8 Nh5

Played after a rather long think. It makes black's position objectively worse but I suppose he wanted to give Aronian a chance to go wrong. In fact Aronian continued to play fast and confidently.

11.c5 Qxb2 12.Bd2 Bxd4 13.Nf3 Nd7 14.Qxf8+

White doesn't mess around giving black any counterplay.

[14.Qxa7 was also playable.]

Viswanathan Anand beat Wang Hao. Photo © 2011 www.tatasteelchess.com.

Wang Hao was another player who appears to have walked into a prepared line. If, as I suspect, Viswanathan Anand had prepared this sacrifice (which in fact he had, for Vladimir Kramnik in 2008 according to the official site round summary) and Wang had not, I think Wang pretty much had no chance today. As it was Anand smoothly converted the position to a win.

Position after 20...a6

You wouldn't want to have this position without preparing it in advance. This move is a concession in an already very difficult position for black.

Alexei Shirov against Maxime Vachier-Lagrave. Photo © 2011 www.tatasteelchess.com.

Alexei Shirov was another player who may well have been close to losing before his opponent left preparation. Maxime Vachier-Lagrave's 18...Rxc1 was an improvement over known theory, and whilst the position looked a little scarey for black, computer analysis by Vachier may have left him completely fearless. After 21...Qd6 Shirov thought for a very long time but couldn't find anything to breath life into his position and after that he was reduced to increasingly desperate attempts to cause problems that predictably failed.

Alexei Shirov

Position after 22.Ng3

Having failed to find anything concrete Shirov finds a bad idea.

[22.Rf4 Re8 is a very nice defensive idea.; 22.Rf5 Qb4 23.Kf2 doesn't look very appetising either.]

22...Rg8 23.Bc4?!

White just has to try his best here but this isn't very good.

23...Ne5 24.Bb3 d3 25.h3 Ba6 26.Rf4

White is losing so he tries burning his bridges. Rd1 or Qd2 would lose, just slower.

26...d2 27.Kh2 Qc5 28.h4 Nd3 29.e5 Nxf4 30.Ne4 Ne6 31.Bxe6 Qc6!

Black has just been accurate in all his defensive ideas and again he is the most precise.

Magnus Carlsen takes a lot of risks in the opening and today it looked terribly difficult for him against Ruslan Ponomariov. In a hedgehog style structure Ponomariov looked to have a lot of choices. Certainly his 17.c5!? looked very dangerous but today he found a determined Carlsen who found a number of only moves (sometimes its easier when its like that) to hold the draw.

The C-Group looks like it will be a very exciting competition. Joint leader Kateryna Lahno lost to Mark Van Der Werf, However Daniele Vocaturo beat tail-ender Jan-Willem De Jong to lead on 3.5/4. Canadian Mark Bluvshtein and young star Illya Nyzhnyk also won to be half a point further back. Even at this early stage I expect the winner to come from one of these three players.
