Sliders can only move to the most distant destination on any ray.
The Betza move notation for this looks a bit awkward,
because it uses an extra 'back-and-forth' move to test for the obstacle,
and combine that with 'capture & unload' trick for hopping over friendly pieces only.
(So they won't also be able to stop just in front of an enemy piece they could capture.)
