Ricky Walden holds a 9-7 lead following the second session of his Betfair World Snooker Championship semi-final against Barry Hawkins.
Walden had led 6-2 following the first session, but Hawkins kept his hopes of a Crucible Final appearance very much alive by winning the second session 5-3.
Hawkins began the second session by taking the first two frames to narrow the gap, before Walden got off the mark for the afternoon to make it 7-4.
Hawkins hit back again to make it 7-5, but Walden fired a break of 106, his third century of the match, to lead 8-5 before a dogged Hawkins clawed his way back to 8-7.
Hawkins was determined to better his best break of 36, and he reached that same mark in the 14th frame before taking on a pink that he optimistically decided could be potted. Instead he ran into a red close to the pink, fouling, but fortunately it did not prove costly.
And when Hawkins finally did get going on a break in the next frame and went beyond 36, he allowed himself to make a small fist pump, with the crowd responding, knowing how badly he had been suffering.
Walden would have kicked himself had he been level overnight, and he at least avoided that thanks to a break of 53 in the last frame of the session.
