Judd Trump overcame Thepchaiya Un-Nooh to reach the semi-finals of the Champion of Champions event at Coventry's Ricoh Arena, winning 6-3.

The match was a repeat of Sunday's final of the Yushan World Open, which Trump won 10-5, and it was another comfortable success for the reigning world champion.

Trump earlier whitewashed Stephen Maguire 4-0 in his group semi-final and was the same score ahead of Un-Nooh at the mid-session interval in their best-of-11 group final, knocking in two century breaks along the way.

Un-Nooh, who edged out Kyren Wilson in a last-frame decider in his group semi-final, got on the scoreboard in the fifth frame with a break of 73 and managed to narrow the gap to 5-3.

However, Trump completed the victory with a 71 break in the ninth and will now face Mark Allen in Saturday's semi-final.
