An enthralling first-round World Championship match between Ding Junhui and Stuart Bingham had to be halted with the scores level at 9-9 and heading into a deciding frame.
Bingham, the 2015 champion, was clearly upset by the decision but tournament rules mean a frame cannot start within 45 minutes of the next session.
Ding held a one-frame overnight lead at 5-4, but pulled the score back to 7-7.
Bingham then edged ahead at 9-8 but could not reach the finishing line.
The pair will resume after the first of the two evening matches concludes.
The other afternoon match saw world number two and 2019 champion Judd Trump on top from the off as he built a 7-2 lead over qualifier Liam Highfield.
Bristolian Trump, who has won five ranking events this season, kicked things off with a rapid century
And a dominant performance followed, with four further breaks of more than 50 taking him within three frames of a second-round meeting with Dave Gilbert.
Lisowski gets Carter
Earlier, world number 14 Jack Lisowski survived an almighty scare to win a gripping final-frame decider with two-time finalist Ali Carter.
Lisowski was 5-4 ahead overnight but qualifier Carter, on his 18th Crucible appearance, led 6-5, 8-6 and 9-8.
A nerveless break of 82 forced the first decider of this year’s event and a score of 60 helped Lisowski progress.
“I stayed strong mentally and managed to turn it around,” said Lisowski, 29.
“It doesn’t get any closer but I managed to win so many close frames. I cleared up at 8-6 and to have won from there is great.
“I’ve never won a tournament so why not make the World Championship the first one? It would be amazing.”
Allen in a hurry
Northern Ireland’s world number 13 Mark Allen scored three centuries as he romped into a 7-2 lead over Chinese qualifier Lyu Haotian.
A stunning break of 139 – matching Kyren Wilson’s Crucible high score – set him on the way to a 4-0 lead.
And although Lyu improved, Allen’s potting power was too much for the 23-year-old as he moved to within three frames of victory after the first session.
Still to come
Allen’s encounter with Lyu plays to a finish on Tuesday evening, while Barry Hawkins, a five-time Crucible semi-finalist and the 2013 runner-up, faces qualifier Matthew Selt.
