India's Koneru Humpy, the highest rated woman player, got off to a bad start with three zeroes, but managed one win over Mariya Muzychuk of Ukraine.
Meanwhile in draughts, Dutch star Roel Boomstra proved he has the makings of a world title holder as he defeated Ukrainian Iurii Anikieiev in the first round, before also overcoming Cameroon's Jean Marc Ndjofang, and drawing with Russian Alexander Shvartsman and Ukraine's Artem Ivanov.

In xiangqi, German player Michael Naegler and Minghao Xie of Singapore battled it out for 80 before Xie triumphed thanks to his solid basic skills at an end game.
There was also further success for the host nation as the women's game saw Sinan Tang clinch a smooth win over Dan Jia, while Vietnam's Huangyan Ruan overcame Hong Chang of Australia.
The bridge competition saw a brilliant auction by the United States on board 17 of the match that placed Team Monaco in danger of losing their second straight round after they suffered a loss at the hands of Team Israel in the morning.
However, Monaco bounced back by board 19 as Tor Helness registered a lead that saw him and Geir Helgemo defeat the contract by their opponents and win the second round.
Italians Fulvio Fantoni and Claudio Nunes made a blunder in the third round when a misunderstanding between the Team Monaco duo on a bid led to a massive loss of 14 points.
The pair did recover and managed to beat Team China in the last round of the day.
Finally in the Go action of the go action of the day, Natalia Kovaleva of Russia managed a rare European win over Kai-Hsin Chang of Chinese Taipei in the women's individual competition, as South Korea come back from the brink to beat Japan in their first round match.
