(CNN) -- Korean Kim Do-Hoon holds a one-stroke lead after the second round of the China Open at Suzhou Jinji Lake International.
The 21-year-old carded a three-under-par 69 for a 36-hole total of 133 (-11) to head joint opening round leader Thongchai Jaidee, Welshman Jamie Donaldson and USPGA champion YE Yang.
"I thought I would be quite nervous as it is a big tournament but I am very comfortable after two rounds," the 2006 Asian Games gold medallist told the official European Tour Web site.
Spain's Pablo Larrazabal (69) and Sweden's Mikko Ilonen (67) share fifth place another stroke behind, with U.S. Ryder Cup captain Corey Pavin still well in touch on 137.
Qualifier Zhang Jin, 14, carded a level-par 72 and missed out on becoming the youngest-ever player to make a European Tour cut, by just a single stroke.
Holder Scott Strange of Australia also missed the cut after rounds of 76 and 72 left him on four-over-par.
