John Higgins drew on all of his previous experience to share the second session of his last-four World Snooker Championship clash with Kyren Wilson.
Higgins, who led 5-3 overnight, took a while to settle as Friday's play got under way and a missed black off the spot allowed Wilson the chance to build up an early lead.
With both pink and black out of commission, it was hard going for the Kettering potter, who was forced to make do with a diet of balk colours and the blue, but he continued to pull out the pots.
Higgins was able to return to the table but he couldn't claw his way back into the frame and it was Wilson who drew first blood to reduce his overnight deficit.
A fantastic red to the middle looked to have presented Higgins with a glorious opportunity in the next frame, only for a missed pink to the same pocket to hand Wilson a reprieve.
Like Higgins, he couldn’t make full use of it and following another scrappy spell, it was the Scot who took control when building a 25-point lead with only 35 remaining.
Wilson fought hard but couldn’t force a mistake from Higgins, who sealed the frame with a long red to move 6-4 in front.
In frame 11, a couple of errant safety shots allowed Higgins to build another substantial lead and he didn’t give Wilson the chance to counter, some superb safety play enough to see him go 7-4 in front.
Wilson ensured he didn't slip further behind when winning the next, a long red giving him the chance to make a frame-winning break of 65 and reduce his arrears to 7-5 at the mid-session interval.
When the players returned from their break, Higgins got in first but failed to develop the reds ideally when going into the bunch and a wonderful snooker from Wilson gave him a fine chance with the reds nicely placed.
A break of 44 was enough to leave Higgins needing a snooker and despite having to hit the brown when tight behind the blue, Wilson wasn’t to be denied and once again got within one frame of the four-time world champion.
Frame 14 could prove to be a turning point in the match, though, Higgins again coming out on the right side of a close contest after more poor positional play from Wilson saw him miss a tricky cut-back black having looked well set to win the frame.
Higgins couldn't capitalise in one visit but when Wilson missed a blue along the bottom rail, the Scot held his nerve to sink the final black.
Wilson displayed great resilience when a flawless run of 74 in the next got him back within one frame.
Higgins left Wilson an easy starter to the middle pocket when trying to nestle into the pack and the Kettering man made no mistake this time.
However, Higgins ended the session as he started it, regaining his two-frame advantage with a couple of workmanlinke visits.
It was hard work for him, but Wilson's frailties in the balls have left him with much to do if he is to make his first Crucible final.
