Indonesia began their quest for a first Asean Championship title by thumping Myanmar in their AFF Suzuki Cup Group A opener at Gelora Bung Karno Stadium.
The tournament co-hosts took control with two goals in three minutes by Budi Sudarsono and Firman Utina in the first half before Bambang Pamungkas sealed victory with a fine finish in the 65th minute.
Myanmar recorded a pair of 2-1 wins against the Indonesians in an invitational tournament in Yangon last month but roared on by the raucous Jakarta crowd, Benny Dollo's side stamped their authority on proceedings from the opening whistle.
Ismed Sofyan nearly put the hosts ahead when his free-kick from 30 metres rattled the crossbar after eight minutes and Arif Suyono had the ball in the net in the 14th minute only to see the effort ruled out for offside.
Indonesia's pressure would pay off in the 26th minute as Budi gathered in a deflected Muhammad Ilham pass and held off the challenges of defenders Zaw Lynn Tun and Min Thu before placing a precise low shot into the bottom left corner of the Myanmar net.
The home side doubled their advantage three minutes later when Ilham made a surging run through midfield before feeding the ball to Utina just inside the box. The Pelita Jaya midfielder turned and fired a shot that flew between the legs of Zaw Lynn Tun on its way past goalkeeper Aung Aung Oo.
Indonesia continued to have the lion's share of possession after the break with Oo punching away a Bambang free-kick in the 48th minute and then getting down low to deny Budi after the forward made a strong surging run through midfield.
Myanmar created little but should have pulled a goal back in the 64th minute when Myo Min Tun's cross from the left picked out Soe Myat Min, who headed over from point blank range.
That miss would prove costly as Indonesia wrapped up the match a minute later through Bambang, who fired an accurate low shot from the left edge of the box across Oo and into the far corner of the net.
Indonesia goalkeeper Markus Harison was fortunate to only be booked for a chest-high kick that flattened Pai Soe on the edge of the box in the 68th minute but he pleased the home fans by tipping over the resulting free-kick from Zaw Htet Aung.
Erol Iba nearly made it four in stoppage time but his close-range header was brilliantly stopped by Oo.
