Poom caused one of the one of the biggest upsets early in the year when he defeated Henson at the EurAsia Cup in Malaysia at the start of the year.
The 25-year-old Thai is looking for another repeat after he held on to his overnight lead by posting a two-under-par 70 to take a three-shot advantage over his idol, Stenson.
Playing in Indonesia for the first time, Stenson carded the lowest round of the day with a 68 to take second place with his three-day total of 13-under-par 203 at the Asian Tour season-ending event.
The Major winner is ready to put up another gallant fight to deny Poom of having bragging rights over him again at the Royale Jakarta Golf Club.
Thailand’s Jazz Janewattananond snatched the outright third place after returning with a 69 to put himself within sights of ending his year inside the top-10 on the Habitat for Humanity standings.
Panuphol, who earned his Asian Tour breakthrough in Indonesia last year, was pleased with his third round efforts after signing for a 70 that placed him in a share of fourth place with defending champion Justin Rose and compatriot Jakraphan Premsirigorn.
With seven shots separating him and Poom heading into the final 18 holes, Panuphol is aware of the challenges ahead and is determined to surmount a late charge.
