Mark Allen overcame three-time world champion Mark Selby to reach the semi-finals of the Champion of Champions event at Coventry's Ricoh Arena, winning 6-2.
Allen earlier defeated Indian Open winner Matthew Selt 4-2 to reach the group final, while Selby secured his spot thanks to a 4-0 victory over Chinese teenager Yan Bingtao.
Selby led the best-of-11 decider against Allen 2-1 before breaks of 69 and 65 helped the Antrim native claim the next two frames.
Allen did not look back from there, stretching his streak to five frames on the bounce to progress with a convincing victory.
The 2018 Masters champion will now face the winner of Group Three, which sees Judd Trump take on Stephen Maguire and Kyren Wilson face Thepchaiya Un-Nooh on Wednesday.
