Graeme Dott continued to look very focused against Mark Selby in the second of the semi-finals at the Betfred.com World Championship.
The Scot who lifted the famous trophy in 2006, holding a two frame overnight lead started well by taking the opener to lead 6-3 and then looked odds-on to increase his advantage in the next.
Selby who was made the favourite to win the world title after defeating Ronnie O'Sullivan, could only look on, as Dott in tenacious fashion constructed a run of 66 before breaking down.
Selby 'The Jester from Leicester' began his reply, knocking in a long red and retained position on the black. He chipped away at his defecit and delivered a quality 63 clearance to steal.
Obviously buoyed from his efforts, he carried this momentum into the third of the afternoon. A 51 break being the main contribution taking the frame 84-0 to reduce Dott's advantage to just the one at 6-5.
Dott who is one of the games best match players, replied immediately. He rattled in 84 to go 7-5 and raised the roof in the next.
He produced only the second 146 break in Crucible history, joining Mark Allen at the top of high-break board and if not beaten, a share of �10,000.
Selby pegged back again taking a scrappy fourteenth frame but that was to be his last frame of the day, as Dott clearly the stronger of the two so far wrapped up another 5-3 session victory.
With breaks of 66 and 86 he extened his frame margin to four at 10-6, needing 17 for his third appearance in the final.
They have two more scheduled sessions to play, Saturday morning at 10am and evening at 7pm.
