There was a feeling of deja vu on the resumption of this Betfred.com World Championship semi-final between Neil Robertson and Allister Carter.
On his first attempt at a long range pot, Robertson stroked it in. The red disappeared with a thud, crashing against the leather.
From there he produced the perfect start to his day, a total clearance of 140. His fifth century and the 56th of the tournament.
The man from Melbourne sealed the second of the day to extend his lead further at 8-2, but this time it was far from easy.
Carter had trailed throughout the frame but forced the re-spotted black, after clearing with 25.
Neither player had a clear cut chance to sink the black until Carters' failed attempt into the yellow pocket.To his disappointment the black stayed in the jaws, leaving the easiest of pots for the Australian.
The teriffic battling qualities that Carter the 2008 runner-up has displayed throughout, were summoned once again. He doggedly won the third of the morning, and followed with a frame winning 76 break in the last before the mid-session.
Carter continued his comeback, taking the next a scrappy 33 minute affair. He then produced his highest break of the match, a 81 to reduce his arrears at 8-6.
Robertson who is also battle hardened from his exploits this year,refused to buckle.
Carters' revival was brought to a halt, after a confidence boosting effort of 59 from the left hander, and was soon to restore his original four frame lead taking the last of the session.
Bidding to be only the second Australian to reach the Crucible final since the late Eddie Charlton in 1975. Robertson finished in fine style with his second century of the morning.
They continue this evening at 7pm with Robertson leading 10-6 in this 33 frame encounter.
