Barry Hawkins moved one step closer to a place in the World Snooker Championship final after dominating the second session of his semi-final with Mark Williams.
Williams was 5-3 behind overnight but made his early intentions clear, a well-taken break of 80 putting immediate pressure on Hawkins who is bidding to make it through to a second Crucible final.
There was no let up from the Welshman in the following frame as he drew level at 5-5 but Hawkins struck straight back with a run of 63 putting him in the lead once more.
Williams came out on the right side of a scrappy frame 12 to draw level once again and he looked set to get his nose in front when making a fine counter attack in the following frame.
However, having left himself with a mid-range blue down the rail with the rest, he missed what was virtually frame ball and Hawkins kept his cool to edge in front at 7-6.
Hawkins was in first in frame 14 but missed a tough black to middle having the lost the cue ball and Williams also ran out of position moments later when attempting to split the pack from the blue.
Hawkins managed to come out on top following a brief period of scrappy play and a break of 56 looked sure to give him a three-frame advantage only a few minutes later.
However, a missed black let Williams back in and he looked to have matters wrapped up until missing the final pink when needing pink and black to steal the frame.
A tense exchange on the pink ensued until Hawkins found a double to the middle pocket to land a real body blow on Williams.
The final frame of the session was a scrappy one but Williams kept himself in touch with a clearance of 62 reducing his arrears to 9-7.
