[Q-odfQ-ubK]cQ seems to work too

Indeed; the u after an o leg apparently is ignored. I guess this is because you always have to end on an empty square with this move, so there is nothing to unload. (With a bit of bad luck it would have created a hole at the square of origin :-) ) Q-f..Q is not recommended, though:it creates a lot of different paths to a distant destination, as every square that is traveled to would be (successfully) tried as an intermediate. So it slows down the AI. With Q-f..K you don't have that: the intermediate square must be the last before the obstacle, or the K step could not hit the latter.
