Judd Trump has warned rivals that he expects to "click" into gear at the World Championships after easing into the second round.
Trump laboured at times against Crucible debutant Hossein Vafaei during the opening round, eventually going through 10-4.
It sets up a clash with Anthony McGill, who can be a tricky customer for anyone on his day.
However, while Trump was far from thrilled with how he opened his tournament, he believes his best snooker will come - and hopefully at the right time.
"I never play well in the first round here, but normally something clicks as the tournament goes on," Trump said.
"There were just too many easy mistakes and I don't feel that comfortable playing out there. I just don't feel like I'm going to clear up every time - that mentality's not there.
"But the matches are so long here that anything can change. It gives me the chance to not play well one day, and the next match I'll play my absolute best. It's hard for me to play well every single time."
Elsewhere at the Crucible, Thailand's Noppon Saengkham pulled off a shock 10-5 win over Luca Brecel.
He had a 6-3 lead overnight and an expected rally from the in-form Belgian never materialised.
The second round matches also got underway on Thursday, with three-time Champion Mark Williams in dominant mood.
He hit three centuries in establishing a 7-1 advantage over Jackson Page.
Stephen Maguire was in the mood to score heavily too, as he produced two centuries to lead 5-3 overnight against the fancied Zhao Xintong.
