In the third round, Lin Dan is set to meet his "bogeyman", Park Sung Hwan from South Korea, who achieved the best head-to-head record against the world No.1 among all other men's singles shuttlers.

It won't be easy for aging Peter Gade from Denmark to stop Lin Dan in the quarterfinals in top half. On the contrary, Sony Dwi Kuncoro from Indonesia could be the highest hurdle for Lee to conquer.

The Olympic bronze medalist enjoyed a comfortable advantage over Lee by a 4-2 margin from six head-to-head meetings. He also delivered a third-round defeat to the Malaysian in Kuala Lumpur in the 2007 World Championships.

If the Indonesian cannot stop Lee, No.3 seed Bao Chunlai, who has reversed his head-to-head record against Lee in favor of the Chinese hopeful, would try to dash the gold medal hope of Malaysia at Olympics semi-finals.
