I rarely watch snooker, but watching Ronnie O'Sullivan in full flow is a rare pleasure that I am loath to miss. He is the sport's genius, and demonstrates it with this extraordinary clearance from a position which the commentator said he'd be doing well to get over 20. Afterwards, Steve Davis captured the essence of what just happened: "Only Ronnie O'Sullivan could have made that break." Only Ronnie. No one else. His genius, his gift, is our pleasure.
