BUILDBASE Bees skipper Scott Nicholls led the way for Great Britain at Brandon as the host nation booked an automatic place in the World Cup Final.
Nicholls scored a brilliant 15-point maximum, backed up by 14 from Coventry team-mate Chris Harris in GB's victory over Sweden, Russia and the USA.
A bumper crowd enjoyed an incident-packed meeting with thrills and spills aplenty, particularly in the second half of the event - but Great Britain, who also included Bees' Olly Allen in the squad, always looked the likely winners.
After initially trailing, the hosts dropped just one point in a run of nine races between Heats 3 and 11, and that established them in front of Sweden.
Jonas Davidsson responded by passing Simon Stead to win the Swedes' joker ride for six points in Heat 12, and the gap was just three after the next race - but the Swedish challenge faded in Heats 14 and 15 as they ran consecutive last places, Harris winning the former race and Nicholls on top in a thrilling battle with Greg Hancock in the next.
Sweden never got the gap to below eight points again, and Britain's progression was confirmed when Edward Kennett held on to third place in Heat 23.
Nicholls completed his maximum by coming from last to first having missed the gate in Heat 25, and Harris dropped his only point to the lively Davidsson in Heat 19, whilst Lee Richardson was a multiple race winner as well.
Sweden, who lost Antonio Lindback with a wrist injury and were already without captain Andreas Jonsson, move into Thursday's Race-Off along with Russia, who did well to overcome the USA for third place.
The two nations will face Poland and Australia at Leszno, with the top two teams there joining Denmark and GB in the Final on Saturday - also at Leszno.
Nicholls said: "I felt good tonight, and the whole team rode with heart and passion, which is what you need in this event.
"If we can carry that through to Poland on Saturday, we've certainly got a great chance of putting ourselves on the rostrum.
"Everyone had their moments and won races, people will say that we've had the easier draw - but we've had the tougher ones in previous years, so it was a brilliant night and the fans were superb."
