Michael Judge is into the quarter-finals of the IBSF World Amateur Championship after two knockout victories in Doha on Sunday.
The Irishman edged 2012 champion Muhammad Asif 5-3 in the last 32 before a more convincing 5-0 whitewash of Manan Chandra.
Judge spent 20 years as a professional player between 1991 and 2011 before dropping off the tour.
He has spent most of the last five years plying his trade on the Irish amateur scene, in which he became national champion in 2013.
The 41 year-old will meet Soheil Vahedi for a semi-final berth after the Iranian pipped fancied young German Lukas Kleckers 5-4.
Meanwhile, defending champion Pankaj Advani remains in the hunt for successive crowns and is up against Thailand’s Thanawat Tirapongpaiboon.
Declan Brennan of Northern Ireland continued his excellent run with a pair of triumphs over Issara Kachaiwong, who compiled a 147 on Friday, and Brian Cini of Malta.
Like Judge, Brennan is up against an Iranian in Hamed Zarehoost, while the last quarter-final tie sees Andrew Pagett up against Mohammad Bilal.
By the end of today, the two finalists will be determined.
