Polearm Gambit is more specific and would be an exception from the wording you have in the previous post.
I disagree. It is about polearm gamble, and I do not think it is at all clear that it's an exception. Obviously you get to attack if they move next to you voluntarily on their turn, and I think that is how it is intended to usually operate. That you get an opportunity attack if they are forced to move next to you on another PC's turn? Not so sure that is the case.
