Top seed and holder Mervyn King stands between Alex Marshall and a record fourth World Singles title after both won their semi-finals in Norfolk. King eased past fourth-seeded Scot David Gourlay, who now represents Australia, 11-1 10-4 in front of the Englishman's home crowd.
And Scotland's Marshall followed that with an exciting 9-7 7-5 win over Welshman Jason Greenslade.
Marshall said: "I'll prepare as usual with a few dances and a few beers."

The Scot has had a dip in form this season and was seeded seven for the tournament.
But he raced to a 9-0 semi-final lead over the third seed before Greenslade staged a fightback.
Marshall held him off before a fluctuating second set, preventing the match going into a tie-break by scoring three with his last ball on the final end.
"Jason put in a great performance in that second set and I'm just relieved to get through," Marshall told BBC Sport.
