LONDON — World and Olympic champion Lin Dan of China makes a belated seasonal bow in Birmingham on Wednesday at the 100th All-England Championships, the oldest and most prestigious tournament in world badminton.

The titleholder, nicknamed 'Super Dan' for his superb attaking ability, skipped the first two Super Series events this year in South Korea and Malaysia after a tiring 2009 but is keen to get back on track.

The Chinese, seeking his fifth men's singles All-England title in seven years, finds himself seeded two behind world No 1 Lee Chong Wei of Malaysia.

If Lin successfully defends the All-England title, he will surpass Dane Morten Frost to become the winningest player in the event.

Frost won four All-England men's singles crowns in the 1980s.

The Malaysian won in South Korea and Malaysia though he has often been outplayed by the mercurial Lin in big matches.

To try to buck the trend, coach Misbun Sidek has had Chong Wei playing lefthanders on a regular basis in training as simulation for the task ahead.

"It is not the same as playing Lin Dan but it will help Chong Wei to prepare for the match," he said .

"More importantly, Chong Wei must also stay focused when playing Lin Dan as it is important to be physically and mentally ready to play the Chinese."

It is hard to see beyond the top two though 2004 Olympic champion Taufik Hidayat of Indonesia has climbed back to three in the world rankings and Denmark's Peter Gade, the world No 5, can never be discounted. England's challenge is led by national champion Rajiv Ouseph, likely cheered by an announcement on Monday that former European champion Kenneth Jonassen of Denmark is to be England's new singles coach from July.
