After four rounds, Aditya Bagus, a 17-year-old Indonesian, is the only leader.

Having been in Penang since 2015, he is undoubtedly no stranger to the city. Here are a few photos of him from that year, when he was nine years old and sharing the platform after receiving a junior prize.

Aditya will play GM Ziaur Rahman, the second seed in the Penang Open, from the pairing from the fifth round.

FM Chan Kim Yew and first seed GM Novendra Priasmoro will face off on board 2.

On board 3, FM Lye Lik Zang is pitted against FM Poh Yu Tian in a Malaysian contest.

IM Oleg Badmatsyerenov, who drew with top seed GM Novendra Priasmoro in the previous round, will face IM Pitra Andika on board 4.
