Holland's Raymond van Barneveld crushed England's Martin Adams 6-2 to claim his fourth Lakeside World Championship.
Van Barneveld missed a host of doubles in the early stages while the 48-year-old Adams started brightly.
But the Dutchman cranked up the pressure to lead 4-1 at the interval while Adams' form tailed off.
Van Barneveld, a winner at Frimley Green in 1998, 1999 and 2003 and a semi-finalist last year, wins £50,000 while Adams picks up £25,000.
Afterwards, Van Barneveld revealed that the occasion had got to him early on.
"I was unbelievably nervous in the first set and I couldn't relax," said the former postman from The Hague.
"I was playing the England captain in England so the crowd made a lot of noise.
"Last year I got beaten in the semi-final and that is not OK because this is what I train for and the stage where I have to perform.
"Frimley Green is my second home and I'm a very proud man."
Adams, a close friend of Van Barneveld, said he had been affected by some unwelcome noise from a section of the crowd but was otherwise philosophical in defeat.
"I don't want to point any fingers but I know some of the individuals and I'll say my piece when the time is right," said Adams.
"It was a good game of darts but I wasn't particularly good early on and it didn't quite go to plan.
"Ray's always a great opponent, that's why we call him 'The Man'. But I'll get him next time."
Van Barneveld, the top seed, was roared on by a large Dutch contingent including Chelsea winger Arjen Robben.
But he looked shaky early on, missing seven doubles to take the first set which Adams pinched.
The England captain, appearing in his first final on his 12th Lakeside appearance, opened with a maximum 180 and a classic looked on the cards.
But Van Barneveld reeled off five consecutive sets as Adams, the oldest ever finalist, faded badly.
A seventh-set whitewash sustained hopes of an Adams comeback, but Van Barneveld weathered the storm to close out with a double 16 and underline his status as the British Darts Organisation's star player.
