he lost 5–1 to Neil Robertson, and the Gibraltar Open where he lost 4–0 to Kyren Wilson. For the 2020 World Snooker Championship delayed by the COVID-19 pandemic, he came through qualifying for the third year in a row with victories over Dominic Dale and Liam Highfield, and was drawn against Ronnie O'Sullivan in the first round. However, in a match played behind closed doors, he was demolished 10–1 in a fastest ever best-of-19 match at the Crucible, which lasted just 108 minutes. Like his previous two first round opponents at the World Championship, O'Sullivan would also go on to reach the final (and, like Trump the previous year, win the tournament). 2020–21 season In a season largely played behind closed doors in Milton Keynes, Un-Nooh struggled to get into a rhythm of winning matches, with his best ranking finishes being last 16 appearances at the Northern Ireland Open, Shoot Out and Gibraltar Open. However his performances from the previous season were enough to propel him into the top 16 in the rankings for the first time by October, and would ensure he would make a first appearance at the Masters.

His season ended with a disappointing 6–5 defeat to Igor Figueiredo in the first round of qualifying for the World Championship. 2021–22 season Despite starting the season ranked 19th, Un-Nooh endured a poor run of form through most of the 2021–22 snooker season, with his best showing by March being a last 32 appearance at he English Open. Despite losing to Fan Zhengyi in qualifying for the German Masters, he made the third maximum break of his career during the match.

He then entered qualifying for the World Championship with relegation from the tour a possibility. He defeated Andrew Pagett (6–4), Jak Jones (6–5), and recorded a first ever victory over Matthew Selt (10–7) to save his tour card and advance to the Crucible. Un-Nooh lost to John Higgins 10–7 in the first round proper. Playing style Un-Nooh is noted for his rapid playing style, and ability
