The 2012 World Championship reaches the business end on Wednesday with all four Quarter-Finals being played to a conclusion on a day of high stakes at the Crucible.
For a number of the remaining players, it could turn out to be a career defining day of snooker as they aim to within one victory of the final.
The first of three sessions features four giantkillers in action, three of which are flying the flag for Wales.
Debutant Jamie Jones resumes his match with the resurgent Ali Carter 5-3 behind after a tense opening session on Tuesday.
Carter showed no signs of fatigue after a thrilling last frame win over Judd Trump as he forged a 4-2 lead, but his 24-year-old opponent demonstrated nerves of steel in making a 127 break to keep the pressure firmly on The Captain.
The duo will return for what is sure to be a dramatic climax later that evening with the reward a tie against either Stephen Hendry or Stephen Maguire.
Two Welsh dragons continue their close-run battle in the morning as former UK Champion Matthew Stevens faces world number 35 Ryan Day.
The duo contested two cagey sessions on Tuesday but a winner will be decided as they bid to become the first player into the semis.
Stephen Maguire looks to seal victory over seven-time world champion Stephen Hendry in the afternoon session.
Maguire has cued beautifully throughout the match so far with a number to high breaks and will be looking to seal the inevitable victory in a short time as he continues his quest for a maiden world crown.
Hendry has lit up the tournament from day one, he made a superb 147 break in his victory over Stuart Bingham and went on to knock out defending champion John Higgins, but his run appears to be coming to a sad end this year.
The main attraction for the Crucible audience in the afternoon and evening features two of the game's most naturally gifted attacking players resume their fascinating battle as three-time champion Ronnie O'Sullivan faces 2012 winner Neil Robertson.
The opening session featured an array of high breaks with the majority of frames being won in a single visit and there is very little between the two on paper and current form to suggest a clear winner.
The first six frames were traded on Tuesday, but left-hander Robertson kicked on and won two in a row before to forge a 5-3 lead.
Many believe the tournament winner will come from whoever prevails through this one, will it be the 'Thunder from Down Under' or fans favourite O'Sullivan?
The action gets underway at 10am GMT, with all matches being streamed live over the a possible nine further frames from the Crucible Theatre, Sheffield.
