Mark Selby launches his quest for a second German Masters title when he faces Dechawat Poomjaeng as the first round draw to a close on Thursday, while Ronnie O'Sullivan is in second-round action at the Barnsley Metrodome.
The recently crowned UK champion, who beat Ronnie O'Sullivan 10-7 in the Final at the York Barbican Centre on Sunday, begins his mission for a fourth tournament victory of the season.
World number one Selby has also captured the Paul Hunter Classic and International Championship titles, but faces a tricky opening test in Poomjaeng, who is ranked 58th in the world.
Judd Trump is another of several big names in action on Thursday. The 2014 finalist opens his tournament against Paul Davison, while Neil Robertson aims to put an end to a run of three straight first-round exits when he plays Lee Walker.
Fellow left-handers Mark Allen and 2011 champion Mark Williams also take centre stage against Sean O'Sullivan and Fergal O'Brien respectively, as world number two Stuart Bingham looks to bounce back from his second-round UK Championship departure against Alfie Burden and 2013 winner Ali Carter faces Wang Yuchen.

Meanwhile, 2012 victor O'Sullivan headlines the start of the second round in the final session of the day.
The Rocket's quest for a second title continues against Gary Wilson as the defence of reigning champion Martin Gould's crown resumes when the Pinner Potter clashes with Craig Steadman.
John Higgins prevailed in a nail-biting decider against Rory McLeod in the opening round, but will be hoping for a much smoother passage when he takes on Zhao Xintong.
World number 17 Ricky Walden hopes to extend bid to return to the top 16 against Robbie Williams, while 2012 runner-up Stephen Maguire plays Noppon Saengkham.
Other notable matches see Northern Ireland Open winner Mark King up against Andrew Higginson and Michael White face off with Liam Highfield.
Play gets underway at 10am GMT on Thursday with all matches being played over the best of nine frames.
