The 31-year-old will receive a rapturous and emotional send-off at the Indonesia Open in Jakarta, a tournament he has won six times with his distinctive, languid style which makes the fast-paced sport seem effortless.
However, Hidayat's chances of bowing out with a seventh win are low, with no major titles to his name in recent years and facing a tough field that includes the world number one and two, Malaysia's Lee Chong Wei and Chen Long of China.
Hidayat -- who famously wept at Athens 2004 as he was awarded Indonesia's first Olympic gold medal -- said he hoped spectators would support him "all the way, whatever the result is". He will start against a qualifier tomorrow.
But the 2005 world champion is giving little away about his retirement plans, telling AFP: "I will remain focused on helping develop badminton, but the details are still secret."
He once split from the Indonesian Badminton Association and based himself in Singapore, and on one occasion was ordered off the courts by security staff after a stand-off with officials at the Southeast Asian Games in Thailand.
