While playing in a 9-Ball tournament recently, my opponent (a weak one)
missed the object ball and the cue ball went around the table toward a
cluster that I knew it was going to break out. The player knowing he had
fouled, snatched the cue ball before it stopped rolling and extended it
toward me in a friendly gesture. He was quite surprised when I snapped
at him for grabbing it before it stopped rolling and he thought that since
he had already fouled that there was no problem in taking the cue ball.
I'd never been in that situation before and I knew that if the cluster had
been broken, I'd have had a much better chance for a run out even though
I still had ball in hand. Is there some kind of extra penalty that could
assesed or did the guy just get a lucky break out of his own ignorance?
