The fourth seed was unlucky to be drawn against Ronnie O'Sullivan on his two previous visits to Sheffield and lost both times, although last year he pushed the "Rocket" to a deciding frame. This time, however, Maguire finally got over the initial hurdle.
It was not exactly vintage stuff from the former UK champion, but his seven half-century breaks were an indication that his game is in solid shape. "All I've been thinking about for weeks has been this match," said the 25-year-old Scot, who will meet Alan McManus or Marco Fu in the second round. "I'm chuffed to bits because I love winning matches, whether it's the World Championship or just in the local club."
Kingmissed the final black off its spot in frame 14, which meant he trailed 9-5 instead of 8-6, and he admitted that had been pivotal. "I played well in patches but missed a couple of balls that cost me," said the 32-year-old.
Earlier, Ken Doherty inflicted a Crucible debut nightmare on rising player Barry Hawkins when he cruised through 10-1, while England's Paul Hunter was defeated by Neil Robertson of Australia 10-5.
