Scotland - inspired by four-times world champion John Higgins and former UK champion Stephen Maguire - lead Group C after they enjoyed a 5-0 win over Israel, one point clear of Belgium who were 4-1 victors against Malaysia.
Maguire said: “We are over the moon with that result. That is better than what I was expecting. It has been a brilliant start to the tournament.”
“We were just concentrating trying to win the match tonight, because Israel are our rivals in the group alongside Belgium," said Higgins. "We’ve stolen a march on them and probably only need a couple of frames in the remaining matches.”.”
