How does forced movement (in this specific case, a push) interact with corners? I have a situation that is as follows:
A uses a power that has a push 1. By how I'm interpreting the rules, B cannot be pushed anywhere - to get to D1, he'd have to move 2 squares (D2, then D1) in the same way as if he were trying to walk around the corner normally. Since a push to D2 would leave him no further than when he started, the push doesn't work.
Is this the right line of thinking, or do the rules allow for a diagonal push in this situation?
