Hi, i have a question regarding the rule convention for 9 ball games. Is it kind of an unwritten law not hit the 9ball by combination into a pocket? Recently I played against a guy who was angry about me doing that, but I'm not sure if he was right because he was playing like an idiot. And if so, are these kind of combos only not allowed after a foul and ball in the hand or always? Thanks for your help, Nils
