The full Quarter-Final line-up will be confirmed by the end of play on Monday as four gripping matches are played to a conclusion at the Crucible.
The opening session in the afternoon features two close-looking matches resume for the third and final time.
Young sensation Judd Trump turned the tables on Sunday as he came from two frames behind to move two frames in front of Ali Carter.
The Ace in The Pack appears to be gaining momentum as each session goes on as he looks to go one step further than last year when he finished runner-up to John Higgins in the final.
He is certain to be pushed all the way by a rejuvenated Carter however and will be wary of the threat posed by the former finalist who is also a clinical break builder.
There is nothing to choose between Matthew Stevens and Barry Hawkins as they play to a finish in the opening session of the day.
The first two sessions of the match witnessed a momentum swing as first Hawkins forged a 6-3 lead, but was kept off the table for long periods on Sunday evening as Welsh ace Stevens fired in top breaks of 80, 87 and 123 in levelling up at 8-8.
The bookmakers make Stevens the 8/13 in-play favourite with Hawkins priced at 13/10 for victory with Bet365
The evening session follows at 7pm and features two young giantkillers as well as two experienced champions in action.
Ronnie O'Sullivan was in imperious form in the second session of his titanic clash with twice world champion Mark Williams and looks to be in a refreshed state of mind just at the right time.
The Rocket is within just two frames of a Quarter-Final showdown with Neil Robertson, meaning the Welshman faces an uphill struggle if he is to perform a famous comeback.
Fans favourite O'Sullivan produced two centuries and a 93 on Sunday afternoon and at one stage went 295 points without reply.
Playing with a new tip on his cue, the three-time champion of the world is matching his undoubted natural ability with a new-found mental strength.
Debutant Jamie Jones has taken the tournament by storm so far and is within touching distance of an unlikely Quarter-Final spot.
The 24-year-old starlet, who is among a host of players flying the flag for Wales, picked up five consecutive frames to storm into a 7-4 lead and went on to finish the session with a sensational double on the black to lead Andrew Higginson 10-6.
Despite being a fairly low scoring affair so far, both have demonstrated a fine safety game and will be desperate to make through given the number of seeds who have exited the competition.
The action gets underway at 1pm GMT, with all matches being streamed live over the a possible nine further frames from the Crucible Theatre, Sheffield.
