World number four Gary Anderson scraped through to the second round of the ladbrokes.com World Championships with a thrilling 3-2 win over Jyhan Artut.
Last year's runner-up looked like exiting the tournament on a number of occasions, certainly at 2-0 down and later with Artut throwing for the match, but he somehow found a way through, winning 1-3 1-3 3-1 3-1 6-5.
In a pulsating fifth set, both players missed four match darts, before Anderson checked out on 76, displaying the composure that had evaded him for most of the night.
A clearly drained Anderson told Sky Sports 2: "I missed, then he missed. I was working out about eating my Christmas dinner as it looked like I was out.
"It's definitely a wake-up call. I have been struggling to get to the dart board to practice. That was a wake-up call."
Artut will be left to dwell on three squandered doubles in a row, any of which would have given him the victory.
Unlike Anderson, world number 15 Colin Lloyd was rarely troubled as he saw off Darin Young 3-1.
Lloyd started off with a maximum 180 but was unable to take numerous chances to finish things off, losing the first set 3-2.
He never looked back after that, though, levelling with a 15-darter and then checking out on double five to move 2-1 ahead.
He broke throw in the third leg of the fourth set and that was all he needed to take it 3-1, running out a 2-3 3-1 3-1 3-1 winner.
He will now play Andy Smith or Scott Rand for a place in the third round, and told www.pdc.tv afterwards: "I didn't let my head drop after falling behind."
Another man who enjoyed a 3-1 win was Michael van Gerwen, who showed signs of the form that saw him installed as a rising star a couple of years ago as he beat Colin Osborne.
The 22-year-old Dutchman broke Osborne's throw in the first leg by checking out on 108, and took the set 3-2.
Osborne responded with a break of throw at the start of the second, but Van Gerwen - aided by a 180 - hit back and signed out with a double-top.
A 3-0 win helped Osborne come back to within a set, but checkouts of double 10 and top helped Van Gerwen over the line 3-2 3-2 0-3 3-0.
"I'm very pleased tonight as Colin is a tough player," Van Gerwen said.
Terry Jenkins made short work of Joe Cullen as he raced to a 3-0 (3-2 3-0 3-1) victory.
