The only Indian to get past the quarterfinal stage, defending champion remained on course to hold on to his Asian Billiards title here Wednesday.
Advani is evidently not in full billiards mode yet after having to switch from snooker post his victory in the inaugural Asian Snooker Tour in Bengaluru last week.
Dhruv Sitwala, Sourav Kothari and Dhvaj Haria lost their quarterfinal ties.
Advani overcame Indian junior champion Shrikrishna Suryanarayanan 5-2 to march into the semifinals and confirm India's only medal in this year's Asian Billiards edition.
He faces former champion Praput Chaithanasakun of Thailand in last-four stages while the other half sees two Myanmar cueists - Nay Thway Oo and Chit Ko Ko - fight it out for a spot in the final.
Advani defeated Shrikrishna Suryanarayanan 5-2: 102(93)-11, 51-100, 102(87)-64(56), 100(51)-0, 69-100, 100(99)-42, 103(71)-25.
