Wijk Aan Zee (The Netherlands), Jan 24 (Agencies): World Champion Viswanathan Anand played out a draw against Levon Aronian of Armenia in the eighth round to claw back to the top of the leader board in the 'A' group of 73rd Tata Steel Chess tournament.

The draw helped Anand to join overnight leader Hikaru Nakamura of United States in the lead after the latter suffered his first loss in the tournament at the hands of World Number one Magnus Carlsen of Norway.

Anand and Nakamura jointly share the lead on 5.5 points, but Aronian, Vladimir Kramnik of Russia and Frenchman Maxime Vachier-Lagrave moved within striking distance of the leaders,
a half point behind with five rounds still remaining in the category-20 tournament being played on round robin basis between 14 players.

Up against the Marshall gambit, Anand liquidated to a pawn plus endgame out of the opening but Aronian always had enough resources to maintain the balance.

Carlsen stopped Nakamura's dream run with a clinical victory against the Sicilian Najdorf.

Amongst other interesting encounters, Alexei Shirov of Spain secured his first victory in the tournament after a disastrous start at the expense of Alexander Grischuk of Russia while local lad Anish Giri came back strongly with a fine victory over Wang Hao of China.

In the 'B' group being held simultaneously, Grandmaster Surya Shekhar Ganguly played out a draw with Li Chao of China to inch to three points in this section out of a possible eight.

The lead positions changed here as youngster Wesley So of Philippines secured his fourth victory on the trot to emerge as the sole leader on six points. Ganguly needs a miracle to make things work from this stage.

International Master Tania Sachdev, however, continued with her impressive run that has won her many fans in this coastal town. The Indian scored her fourth win in the category-11 tournament to remain in with a chance to get her second Grandmaster norm.

Tania defeated IM JW De Jong of Holland who is having a tough time in the tournament.
Grandmaster Daniele Vocaturo seems to be on course for the title in this section with 6.5 points so far -– his lone loss was against Tania in round six.
