Ken Doherty was beaten 5-4 by Jimmy White in the World Senior Snooker Championship final at the Crucible on Saturday.
The interval had a massive impact on the match, as Doherty failed to get over the line in the end having dominated the opening session.
The victory sees White quality for the Champion of Champions event which is due to take place in November, while he also collects a cheque for £25,000 (€27,700).
Doherty took all four frames before the interval, as he mixed breaks of 93, 46, and 56 with some solid safety play. But the Whirlwind did himself no favours, missing good chances in at least two of the frames.
White, who lost six professional world finals, finally got off the mark with a break of 42 in the fifth, and he had another frame after the Dubliner missed a straight forward black off the spot.
The seventh was a particularly scrappy affair, and The Whirlwind closed the gap to the minimum after Doherty missed a glorious chance to wrap up the match.
A poor effort on the blue left the Ranelagh-native with a tricky pink, which, using the rest, he didn't get close to, and White did the dutiful.
A break of 79 in the next forced a decider, and the former world number 2 claimed it with a break of 85 in the last to defend his title.
