BBC Sport at The Crucible
Scotland's Graeme Dott moved into the second round with a nervous 10-9 win over Mark King at The Crucible.
Dott held his nerve in the final frame
King took the session's opening frame on the black for a 6-4 advantage before Dott took a scrappy 11th frame.
The pair continued to trade frames in dogged fashion with neither player able to pull clear until King's 64 break put him within touching distance at 9-8 up.
Dott dug deep in a tense 18th frame to force a decider, which both could have won, before the Scot prevailed.
Mark King was angry at the way he played the match.
"I don't think I've ever been involved in such a scrappy match," he said.
"The last couple of days I've been performing like a club player and it's so frustrating to come here and play that bad.
"Players who are already out of the tournament will be wishing they'd been drawn to play me or Graeme."
Dott admitted he could hardly have played any worse despite emerging victorious from a final-frame decider.
"That must have been one of the worse matches ever played here," he said.
"It was actually getting embarrassing how bad the game was.
"I honestly never thought I was going to win, but I'm going to change my tip and I certainly can't play any worse against John Higgins."
