STUART Bingham clinched the final frame of a tense and cagey session to level his World Snooker Championship semi-final against Jak Jones at 8-8.

Basildon's Bingham finally came through the 16th frame to leave a war of attrition all-square, while there was nothing to separate Kyren Wilson and David Gilbert in their last-four clash, which will resume on Friday night also at 8-8.

Jones, who battled back from a nervy start and 3-0 down to finish Thursday night’s session level at 4-4, saw Bingham take Friday’s opening two frames.

Bingham opened up a 6-4 advantage with scores of 70 and 107 – the first century of the match – with the latter break punishing a risky missed plant on a red by Jones.

The Welsh qualifier was struggling to take his limited chances, but pulled it back to 6-5 with the help of a fluked pink before both players missed pots in the 12th frame.

Jones missed a pink with the reds nicely spread, but Bingham failed to punish him by missing a black while at full stretch and the world number 44 drew level at 6-6.

Bingham then fell behind for the first time in the match, losing a safety exchange before a score of 68 from Jones was enough to edge him 7-6 ahead.

Both players agreed to a re-rack in the 14th frame after another scrappy safety battle, but neither could find fluency and 30 cagey minutes later Bingham made it 7-7.

Jones edged ahead with a break of 69, but in the final frame of the session he gave away 49 points in fouls as Bingham levelled it up once again.
