It doesn't seem as complicated to me. That answer depends on the circumstances of the decision to change intentions, mainly involving a lack of a preemptive intention to do so. An intention to change intentions is no intention at all. It is just an indicator of hat the true intentions always were.

But that's the thing: How could you change intentions like that? You know the rules of the game beforehand. Either you intend to change intentions or you have to drink it.
