The other quarter-final clash sees in-form Mark Allen take on 29-year-old debutant Jak Jones.

Allen, who won three ranking tournaments between October and January before seeing his form dip a little has looked at his ease so far, crushing Stuart Bingham 13-4 last time out.

"He’s a lot lighter, can reach different shots. He’s feeling good about
