I once gave a spot ... at anytime i wish, throughout the entire frame...
i could only shoot a total 5 balls regardless of the point value..I won 55-53, and it was one of the toughest games I ever played. ..I had to run out the blue, pink and black to do it...
Steve Davis once lost the deciding frame of a match for 3 misses, at 'hill-hill' as you guys call it.
Not without anything being potted, but still a bit of an unplesant way to go...
