I had an opp accidently, (uh-huh) nudge a ball about 1/2 inch while shooting his target ball. He moved it back voluntarily before I could say a word ,and apologized for moving it. I noticed he didn't place it exactly where it originally was, but said nothing. Two shots later, his CB came around for perfect angle back to his corner via 3 rails. I said nothing when he moved the ball, so I let it go knowing I had been taken advantage.
ANYTIME that an idle ball gets inadvertently moved; its an issue.
No rule about them shooting it next.
So,..... I gotta ask.
Did the nudge give him advantage??
