This move is a time-tested workhorse. It’s a catch-all for any occasion where you need to go to dice but there is no move that covers the situation in the fiction. It’s perfect for when there’s a race between a protagonist and someone else, a time constraint like a ticking clock, or whenever someone with means wants to keep a protagonist from doing something. The crucial factor here is the means. If there’s no conceivable way to stop a player character, there’s no real move to make; they just succeed.
