Trump, Allen and Robertson progress in British Open
Judd Trump, Mark Allen and Neil Robertson have progressed to the third round of the British Open at the Centaur in Cheltenham.
World number one Trump claimed a 4-2 victory against Ryan Day of Wales, the 2022 British Open champion.
Trump, 35, must wait a little longer to claim the 1,000th century break of his career as the best the Englishman managed against Day was 80 in the final frame.
Allen, from Northern Ireland, ran out a 4-1 winner over Aaron Hill from the Republic of Ireland, while Australian Robertson saw off Scotland's Chris Totten by the same scoreline on Tuesday afternoon.
Fresh from winning the English Open on Sunday, Robertson moved two frames in front with breaks of 100 and 99, before Totten replied with a run of 79 to reduce the arrears.
Robertson, 42, responded with an 86 and 53 to get over the line and continue his revival after a difficult couple of years.
A day after complaining about the conditions at the British Open, saying the table should be "burned", Allen bookended his match with centuries, beginning with a 102 break and adding a 56 in the next to establish a two-frame advantage.
The world number three recovered from a 50-point deficit to claim frame three, and although Hill came out on top in a scrappy fourth, it proved only a temporary reprieve as Allen, 38, then knocked in a 101 to secure victory.
Trump's bid to reach 1,000 centuries will continue in round three against compatriot Mark Davis, who beat Xiao Guodong 4-2.
Only two players have reached the landmark before - Ronnie O'Sullivan in 2019 and John Higgins during his 4-3 defeat by Allen in the English Open last week.
Ukraine's Iulian Boiko, who turned 19 on Sunday, claimed the best win of his career. Boiko, who is not currently on the professional tour, beat Si Jiahui 4-1 and will face Welshman Jak Jones, a 4-0 winner against Alfie Burden.
Allen will take on either Hammad Miah or Ben Mertens in round three, while Robertson will play Mark Joyce or Rory Thor, conqueror of Mark Williams.
