I was just wandering what the best way to question an opponents line call was. It really annoys me when people ask..."are you sure?" or say..."you know the lines are in." What do they think I'm going to say, "no, im really not sure, you go ahead and have that point" or "OH, the lines are IN, okay, nevermind, your point!" This being said, what is the best way to let an opponent know that you disagree with their line call?
