by Liang Ziming
5/26/2013 – After six rounds, the Danzhou tournament held in China has seen GM Ni Hua take the lead with 5.0/6, followed by top-seed Ding Liren with 4.5/6. One of the surprises has been the comeback by Xiu Deshun who lost his first two games, and then won four straight. Though Wei Yi has had a rough start he is a veteran in top chess in China. IM Lou Yiping annotates in the illustrated report by Liang Ziming.

This traditional round robin tournament, with a total prize fund of 300,000 yuan, gathered ten top Chinese GMs, without China’s no.1 GM Wang Hao and the former women world champion GM Hou Yifan, who are both preparing their mid-semester exams at the Beijing University. Hou Yifan will fly to Danzhou to attend the simul and a special challenge game on the rest day on Sunday.

After six rounds, GM Ni Hua is in the sole lead with 5.0/6, after four consecutive
wins in rounds one through four followed by two quick draws in round five and six.

The 30-year-old veteran Ni Hua has had a wonderful start by beating Xiu Deshun,
Lu Shanglei, Wei Yi and Zhou Jianchao. In the game with Wei Yi, Ni Hua easily got a
full point when the 13-year-old grandmaster astonishingly blundered a piece in the middle game.

IM Lou Yiping annotates Wei Yi-Ni Hua:

Top-seed Ding Liren, facing Wen Yang, has been hot on Ni Hua's tail

A half point behind the leader is the top seed GM Ding Liren (2707 Elo), who scored three wins and three draws. After starting with two wins against Lu Shanglei and Wei Yi in the first two rounds, Ding’s next victory came in round four, where he easily refuted Wen Yang’s overly optimistic sacrifices on the kingside.

24-year-old GM Xiu Deshun, the newcomer of Danzhou Tournament who suffered
losses in the first two rounds, attracted the most attention by then winning four games
in a row, successively defeating Zhou Weiqi, Lu Shanglei, Wei Yi and Zhou Jianchao.

In the fifth round, Xiu Deshun as black seized the initiative and won a piece by capitalizing on a mistake by Wei Yi in the complicated middle game that arose from a popular variation of the Sicilian Najdorf. He went on to seal his win after successfully preventing White’s perpetual check attempts.

The defending champion Bu Xiangzhi shares third place with Xiu Deshun with
4.0/6 after a quick draw with Ni Hua with his pet Petroff Defense.

GM Yu Yangyi, the winner in 2011, scored his second win over GM Wen Yang in
a complicated duel in the Ruy Lopez in round six.

Zhou Weiqi and Zhou Jianchao, what are you talking about?
