Mark Allen has it all to do if he's to make his way into the quarter-finals at the World Snooker Championship after he fell behind 6-2 to England's Chris Wakelin.
Wakelin jumped into a two-frame lead before a superb break of 100 saw Antrim man Allen half the deficit.
Wakelin took the next frame, however, to go 3-1 up before Allen hauled himself back into the game.
But it was Wakelin who finished the session strongly, taking the final three in the best of 25 clash.
The match resumes on Friday morning.
Former champion Luca Brecel revealed he always felt he was going to fight back against Ryan Day after overcoming a big early deficit to book a last-16 clash with Ding Junhui at the World Snooker Championship.
The 2023 world champion appeared to be in danger of joining last year's winner Kyren Wilson in crashing out in the first round when he found himself 5-1 down to Welshman Day during the first session.
But the Belgian won the final three frames on Wednesday to make it 5-4 and get himself right back in the match.
A century from Day in the opening frame of the second session put Brecel on the back foot once again but he won three successive frames twice more on Thursday afternoon to close out a 10-7 victory.
Brecel, who won the tournament on the last occasion he made it through the first round in Sheffield, said: "I didn’t really get many chances before 5-1 and then I had a good one, made a century and I felt good.
"I never really panic, especially here as it’s so long.
"I’ve made so many comebacks here so it wasn’t surprising. I always felt like I was going to come back at some point.
"From 5-3 down I sort of felt that I couldn’t really lose – no disrespect to Ryan because we all know what he’s capable of. But I felt so relaxed and I could see he was a bit nervous.
"The way I play means everything needs to work and I’m too lazy to change the way I play. So if it doesn’t work then I go home, and we’ll see."
