Ronnie O'Sullivan at centre of 'chalkgate' scandal in World Championship controversy: Snooker stars call for old-school tactic that 'destroys the game' to be BANNED

Seven-time world champion Ronnie O'Sullivan is at the centre of a controversy at the Snooker World Championship over his use of Triangle chalk, a traditional brand that leaves visible streaks on the table and can cause 'kicks' — unwanted deflections of the cue ball — during matches. Fellow snooker professionals are calling for the old-school chalk to be banned, arguing it disrupts fair play and damages the integrity of the game. O'Sullivan is described as one of the only remaining players still using Triangle chalk, making him the focal point of the 'chalkgate' debate.
