Two acid tests await the Malaysian shuttlers at the on-going All-England Championships, with Lee Zee Jia facing China’s Chen Long and Aaron Chia-Soh Wooi Yik taking on Marcus Fernaldi Gideon-Kevin Sanjaya Sukamuljo.

Lee, who swept away Indonesia’s Jonatan Christie 21-15, 21-13 in the first round, was in top form to dispose Lu Guang Zu 21-10, 21-16 on Thursday, needing only 36 minutes to dispose the Chinese

He should be fresh for the challenge of Chen Long on Friday, who himself was impressive in disposing national team-mate Lin Dan 21-17, 21-8.

Lee has beaten Chen once in three meetings when they met at the Indonesian Open last year.

As for Chia and Soh, the men's double pair have the unenviable task of taking down the top seeded Indonesians, whom they have never beaten before.

The duo last played the world number one pair at the Asia Team Championships in February, when they lost in straight sets.

Meanwhile, the rest of the national contingent all crashed out in the second round, including mixed doubles pair Tan Kian Meng-Lai Pei Jing, men’s doubles pair Ong Yew Sin-Teo Ee Yi and women’s doubles pairs Vivian Hoo-Yap Cheng Wen and Chow Mei Kuan-Lee Meng Yean.
