The reaction of Ken Doherty and Willie Thorne says it all.
Scoring a maximum 147 break at the World Snooker Championships doesn't earn you as much as it used to, but it's still worth £30,000 to anyone that can pull it off.
Ding Junhui was well on track to do so against Mark Davis and had racked up a break of 96 when he inexplicably decided to play for the blue rather than the black.
Seconds later, he knew he had messed up.
Maybe next time Ding.
