The 31-year-old Glaswegian has seen countrymen Stephen Hendry, John Higgins and Graeme Dott roar to glory in Sheffield, but is still waiting for the moment his turn comes to triumph.
To assist his cause, the gritty Scot is working on the premise that opponents can be ground down by the mental punishment which comes with losing tight frames.
Maguire had several of those in his 13-7 second-round victory over Joe Perry, the formalities of which he completed on Saturday morning after returning for the final session with an 11-5 lead. Hendry awaits him in the quarter-finals, following his victory over Higgins.
Despite reaching the China Open and German Masters final over the past three months, Maguire claims his game is not in pristine shape, but there are other ways of beating players than firing big breaks.
"I've just been stealing matches and winning matches. I've not been overpowering anybody," he said.
"To be honest I would rather be stealing matches because it hurts the opponent even more.
"I'd rather steal frames. Sometimes it's nice just to get in first, make an 80 break and finish it quickly.
"When you steal, it seems to kick the other guy, which I quite like doing."
