If a player gains an advantage not intended by rule, then I'm calling a violation when he goes out of bounds.
I've only had one of these in a game. I'm the lead, A1 goes around a low post screen, and in doing so intentionally goes out of bounds, almost running into me. It surprises me, so I say to myself "I'm calling a violation if he does this again". After a foul switch down the other end, we're back with the same team on offense, but with my partner as the lead. A1 again goes around a low post screen, and in doing so intentionally goes out of bounds, almost running into my partner. He calls the violation (with no input from me). The coach requests an explanation. When my partner explains the violation, the coach looks at my partner like he's from Mars.
