    It is well established that option 2 works, while option 1 doesn't. 1 doesn't work because the delta T is too low.

    Option 2 works for the reasons you mentioned, negative pressure in the far room, positive in the stove room, the path of least resistance is the "return", the open doorway through which the warm air passes, thereby following the laws of thermodynamics.
