Ronnie O'Sullivan will go down as a legendary figure at The Crucible - despite once nearly snapping his cue in frustration in a second-round match.
'The Rocket' will go into the remainder of his World Snooker Championship semi-final with John Higgins leading 10-6, following a scintillating display on Friday. With the match locked at 6-6, O'Sullivan turned on the style, winning the final frame on a re-spotted black to take full control.
Prior to that, he produced what BBC commentators described as the shot of the tournament when he potted a long red and still got position on a difficult black. Should he prevail against Higgins, he'll face the winner of Mark Williams and Judd Trump in the final.
O'Sullivan is chasing Stephen Hendry's record number of seven world titles, but as always, his tournament has not been without controversy. In his first-round match with David Gilbert, he was reprimanded for making a lewd gesture after missing a simple black.
It's not the first time he's irked Crucible chiefs though. Back in 2013, he famously lost his temper when coming up against two-time finalist Matthew Stevens, and his cue very nearly paid the penalty for it.
After missing a routine red, the now 46-year-old showed his anger by slamming his cue onto the table. Somehow, it didn't snap in half, and he regained his composure to eventually win 13-5.
His challenge would end in the next round though, beaten by eventual champion Stuart Bingham 13-9. Of course, there are many more occasions where the legend has risked the wrath of bosses.
In that same tournament, in his first-round match against Craig Steadman, he decided he would briefly play in just his socks. He eventually left the arena and returned in a new pair of shoes, lent to him by tournament director Mike Ganley.
Way back in 1996, he upset Canadian opponent Alain Robidoux by opting to play left-handed after building up a comfortable lead. He was involved in further controversy during that tournament when he head-butted Media Official Mike Ganley and was fined £20,000.
