Hidayat didn't enjoy starting the group decider at 9:20 a.m. He blew a 19-17 lead and had to save a game point at 20-19, but controlled the rest of his first matchup with Abian.
"I never play early mornings, I'm not an early morning person," Hidayat said. "My body is still adjusting. Because I play too early, it's like I'm still sleeping."
Hidayat, the gold medallist in Athens eight years ago, will face Beijing champion Lin. The mercurial Hidayat won their early matches, but he last beat Lin in the 2006 Asian Games final in Doha. The Chinese star has won all nine matches since, including in the All England Open quarterfinals in February.
"I'll need to prepare more. It's going to be a good match," Hidayat promised. But when asked if he was still good enough to beat Lin, Hidayat said, "Before, not now ... we'll see."
