Hyderabad, Aug 10 - Chetan Anand lightened up the otherwise gloomy first day for the Indian shuttlers at the World Championships, advancing to the second round with an easy killing of South Korean Ji Hoon Hong at the Balayogi Stadium in Gachibowli here Monday.

World No.15 Chetan was in complete command as he dispatched the Korean 21-8, 21-16 in front of a sizeable home support.

Earlier, India suffered their first loss when in-form Rupesh Kumar and Thomas Sanave went down to Japanese Kenichi Hayakawa and Kenta Kazuno in a close battle 13-21, 21-23 in the men's doubles first round.

The Indian duo put up a tough fight against the 14th seed Japanese pair, but lost in 39 minutes.

Arun Vishnu and Aparna Balan went down to Noriyasu Hirata and Shizuka Matsuo of Japan 14-21, 20-22 in the mixed doubles while Aditi Mutatkar lost tamely to Juliane Schenk of Germany 8-21, 12-21 in the women singles.

Chetan, however, played a solid all-round game to bring back cheers among Indian supporters.

'My three-week training in Prakash Padukone academy helped a lot. It was a motivating factor. I made some unforced errors and could have played better. Initially I had problems adjusting to the court. I started in an attacking note and it paid off,' Chetan said.

Defending Champion Lin Dan faced no problem in getting past Israel's Misha Zilberman 21-9, 21-11, in the first round, while Danish World No.3 Peter Gade also sailed past Ukraine's Valeriy Atrashchenkov 21-11, 21-16.

Top seed Lee Chong Wei went past Dieter Domoke of Germany 21-14, 21-12. Chong Wei said that he bit apprehensive because he was playing in the same court where he lost in the first round in Indian Open in March, but felt better as the match progressed.

It was veteran Dicky Palyama of the Netherlands, who created a flutter, upsetting Chinese Bao Chunlai 21-18, 21-14 to advance to the second round.

India had high hopes from the world No.18 doubles pair of Rupesh and Thomas, who recently won the New Zealand Open and were runners-up in Australian Open.
