The tournament, which is being held in Milton Keynes in England, sees 64 of the world's top players compete over 11 days with the winner taking home £30,000 ($36,000/€33,000) when the event concludes on June 11.

At the halfway point of the first stage of the competition which sees the players split into 16 groups with the group winner progressing, Englishman Trump was one of two members of the world's top 16 to reach the next stage, along with world number 11, England's David Gilbert.

Other group winners so far are Wales' Ryan Day, the world number 36, England's Mark Joyce, world ranked 68, Belgium's Luca Brecel, world ranked 37, Harvey Chandler of England, ranked 84, China's Liang Wenbo, the world number 34 and Gary Wilson, of England, ranked 19.

The highest-profile casualty so far is three-time world champion Mark Selby, with the Englishman eliminated from the competition following his defeat by Wenbo today.

The closest group contested so far came on Tuesday (June 2) in the form of Group Nine, where Brecel of Belgium qualified by virtue of a higher break, ahead of England's Jack Lisowski, after the pair finished with identical records of one win and two draws from their three matches.

Plenty of big names are competing in the second half of the first phase of the competition, including five-time world champion Ronnie O'Sullivan tomorrow, Australia's Neil Robertson, the world number two, who is competing on Sunday (June 7) and world number five Mark Allen of Northern Ireland, who plays on Monday (June 8).

The winners from the first phase of the tournament will then be divided into four further groups, with the four winners advancing to the tournament finals on Thursday June 11, where the champion will be crowned.

All matches are played over the best of four frames, with three points awarded for a win and one for a draw.

The tournament is playing behind closed doors with the venue specially selected as it has on-site accommodation.

All tournament staff were throat and nose swab tested ahead of competition, while players are tested the day before their matches.

All staff and players isolate once tested and remain confined to their rooms until the result is confirmed.

There have been no negative tests so far, although there have been withdrawals from the original field, which included Switzerland's Alexander Ursenbacher, after he was unable to make arrangements to travel to the UK.

Measures have been put in place at the tournament to adhere to UK Government guidelines in relation to hygiene and social distancing.

There are no handshakes between players who maintain social distancing at all times, while referees also maintain social distancing as much as is practically possible.

As part of hygiene measures, players are solely responsible for the handling of any extra equipment they may use, such as rests and spiders, which are kept in a designated area near to the match table.

This is a change to usual procedure in which the equipment is kept under the table and handled by referees.
