Trump beat Robin Hull 4-1 with a top break of 104 to set up a last 64 match with Zhao Xintong.
World number five Trump hasn’t won a ranking title for over a year but hopes he is coming into form.
“I played some good stuff in spells, we both struggled a bit,” said 29-year-old Trump. “I feel as if my scoring is coming back. For me it’s about enjoying my snooker, practising hard and trying to learn from some of the other top players while they are still around.”
Higgins beat Li Yuan 4-1 with top runs of 75 and 88 to set up a second round match with Nigel Bond.
“I have been struggling this season and that was probably as well as I have played,” said Higgins, who was runner-up to Mark Selby at the recent China Championship. “I haven’t been practising or playing well since the start of the season. I was surprised that I got to the final in China because my play was terrible. I can try to win matches this week and build a bit of momentum and confidence.”

European Masters champion Jimmy Robertson kept his momentum going with a 4-1 win over Michael Holt, making breaks of 81, 71 and 68.
“I’m on a bit of a roll at the moment and full of confidence,” said Bexhill’s Robertson. “I played really well tonight. I know a lot of people in this area, when I was growing up I was playing in clubs all over Sussex. Quite a few people are here to support me.”
Veteran Jimmy White scored an impressive 4-2 win over China’s Lyu Haotian. That made it back-to-back wins for 56-year-old White as he beat Fergal O’Brien in last week’s International Championship qualifiers. Today, the Whirlwind fired breaks of 81, 74 and 63.
World number nine Kyren Wilson became the only top-16 ranked player to lose in the first round as he went down 4-3 to Thailand’s Sunny Akani. From 3-1 down, Akani took the last three frames with top runs of 78 and 62.
