His victory highlighted a brilliant day for China who for
the first time since 1987 took all five titles.
Chen had finished runner-up in 2009 when he lost to
compatriot Lin Dan but Lin was beaten this time round in Friday's quarterfinals,
leaving center stage for Chen.
The Chinese took his chance with both hands, often
outplaying Hidayat, world champion in 2005 and Olympic gold medallist in 2004.
Chen raced to a 7-0 lead in the first set and though Hidayat
fought back, two errors at the end handed the advantage to the Chinese.
Defending superbly when necessary, Chen led 6-2 in the
second and generally called the shots. Hidayat bravely saved three match points
from 20-12 but Chen was not to be denied.
"Mentally I was very strong today. I prepared very well
and I didn't let Taufik play to his strengths, particularly around the
net," Chen told a media conference.
Hidayat said: "I tried my best today but made too many
mistakes. I was able to get single points but not put a run together." Chen's
victory formed part of a Chinese clean sweep of the five titles.
In an all-Chinese women's singles final, seventh seed Lin
Wang beat Wang Xin, seeded three, 21-11 19-21 21-13.
The mixed and women's doubles were also China-only finals
with Zheng Bo and Ma Jin winning the former and Du Jing and Yu Yang the latter.
The men's doubles pair of Cai Yun and Fu Haifeng, defending
their 2009 title, beat Malaysia's Koo Kien Keat and Tan Boon Heong in three
sets.
The result meant Malaysia remain without a world title since
the tournament was first staged in 1977.
