World Junior champion Pendyala Harikrishna continued with his top form to outsmart Grandmaster Luke McShane of England [Images] and remain in sole lead in the second Sanjin Hotel Cup Grandmasters Chess tournament in Taiyuan, China.

With his third win on the trot, Harikrishna made sure that no one could catch up with him and he remained half a point clear of nearest contender Tigran Petrosian of Armenia, who accounted for tail-ender Woman Grandmaster Zhoa Xhu of China in a one-sided affair.

With eight rounds still remaining in the category-15 round-robin event, the Chinese duo of Dubai Open champion Wang Hao and Bu Xiangzhi, once the youngest GM of the world, are in joint-third spot on 2 points each.

Following them with 1.5 points is former Russian champion Alexander Motylev with an extra game in hand. McShane along with Wang Yue of China is next in line, also on 1.5 points, albeit from three games.

It was a game of academic interest between Mcshane and Harikrishna wherein the former played white. Starting out with the Berlin defense for the second time in the event, Harikrishna was in for a surprise as McShane nonchalantly obtained a superior position soon in the middle game with absolute control of light squares.

It was time to work on the counter active measures for Harikrishna and he executed a fine plan to get some play in the center. McShane could have forced a draw by repetition but the English was obviously not content with a half point after being on top for quite some time.

As McShane starting pressing hard, Harikrishna was quite up to the task too. A flurry of exchanges led to a fairly imbalanced endgame wherein Harikrishna's skills yet again came to fore and he wrapped the issue in 80 moves.

For the second time in the tournament, black pieces reigned supreme with as many as five games ending in the favour of slightly unfaourvable colour in the game.

Petrosian was in his element in defeating former world junior girls' champion Xue, who did not know what hit her soon in the middle game arising out of a Tarrasch defense. With a thematic exchange sacrifice, Petrosian gained a direct attack against the king and romped home in 44 moves.

Wang Hao got the better of his higher rated compatriot Zhang Zhong in a keenly contested game. Playing the black side of a relatively less played variation in the French defense, Hao capitalised on an endgame mistake to register victory in 49 moves.

Chinese Zhang Pengxiang fell victim to some exquisite play by top seed Motylev in a Scotch opening game. Playing black Motylev simply outclassed his rival in the endgame to register his first victory.

The other decisive game of the day was played between Ukrainian Sergey Karjakin and Bu Xiangzhi in which the latter scored in 54 moves while in the lone draw of the day, Ni Hua

failed to impress compatriot Wang Yue.
