Gary Anderson overcame his first-round nerves to beat Andy Hamilton 10-6 in Blackpool - a win which set-up a plum second round tie with world number two James Wade.
Wade was a comfortable 10-3 win over Jamie Caven at the Winter Gardens, but former world champion John Part suffered a first round exit at the hands of speedy Dutchman Vincent van der Voort.
Anderson is a notoriously nervous starter in tournaments and has been ousted in the first round a number of times, but was determined to win his first match on his Blackpool debut.
The Scotsman rifled in a 121 checkout on the bull to go 3-2 up, and he won the second part of his match by the same margin to lead Hamilton 6-4.
A superb Shanghai 120 got Hamilton back to 6-5, but Anderson hit his stride to move 9-6 in front with a 180 and 54 checkout in the 15th leg.
Hamilton missed the bull he needed to stay in the match in the next and Anderson hit tops to go through 10-6 with a 99 average, but he now faces a huge test against Wade in the next round.
"After about the tenth leg I started to settle in, before then I was shaking like a leaf," Anderson said on Sky Sports after the game.
"It's my first time here. Yesterday I felt great watching the darts but when I woke up today I felt really nervous. My first round record in tournaments is not very good so I was desperate to get through it this time."
Wade will be next up for Anderson, after the former Blackpool champion made light of what looked a tricky test against in-form Derby thrower Caven.
"I expected a lot more from Jamie," said Wade. "So I went into the match prepared for a big game but Jamie didn't play his best darts - it's probably an experience for him being in Blackpool for the first time.
"I don't know what it is, but playing here in Blackpool, in the Winter Gardens, it's very special to me. It is the best darts tournament in the world in my opinion. There just isn't anywhere else in the world that can beat this venue.
"There is still more to come from Gary (Anderson), he's the best scorer in the world but my one plus on him could be that I'm a better finisher so it should be a great game."
Vincent van der Voort started quickly, and former world champion Part could not keep up as he succumbed to a 10-6 defeat, and the Dutchman now faces the showman Wayne Mardle in round two.
In the night's final match, Ronnie Baxter emerged triumphant from a superb tussle with Holland's Jelle Klaasen to post a battling 10-8 victory.
