I was making the more general point that impossible situations (abstract arguments that aren’t modeled by any of the “possible” situations being considered) can matter, that impossibility is not necessarily significant. Apart from that, I agree that we don’t actually have a good argument for impossibility of any given action by Player 1, if it depends on what Player 2 could be thinking.
