Ronnie O'Sullivan needs to chalk off Stuart Bingham's bold bid at Betfred World Snooker Championship
Ronnie O'Sullivan escaped punishment for putting his chalk on the table in the Betfred World Championship quarter-final clash with Stuart Bingham at the Crucible.
O'Sullivan - who had broken rules earlier in the tournament when playing some of a frame in his socks - is attempting to battle back from a 5-3 overnight deficit after opening with a century break and then hitting 118 in the fourth frame.
In the fifth frame, the Rocket was fortunate to escape a possible seven-point sanction as he placed his chalk on the table to line up a shot but referee Terry Camilleri did not call the foul.
Bingham, though, recovered to win three successive frames to edge ahead, with the best-of-25 frame match concluding tonight.
Barry Hawkins - conqueror of Ulsterman Mark Allen - led Neil Robertson 5-3 overnight.
Hawkins, runner-up in 2013 and a semi-finalist last year, took a 35-minute opening frame on the colours, then 2010 champion Robertson responded with breaks of 115 and 70 in winning three in a row.
But the Australian failed to score a single point after the interval as world number five Hawkins reeled off four frames on the spin.
