Stun run thru for the 3. Follow for the 2.Here's the kind of shot I was thinking of when I created this post. You've got to hit a window maybe 6-8 inches wide to shoot the 2 in the corner. To roll forward requires a pretty soft hit, but it's an easy shot. To me, the firmer/lower hit is a lot harder.

I think stun run thru for a shot where cueball is 4 or more feet from object ball and you need to roll ahead a inch or three.
I think stun follow is hard follow for changing path of cueball upon contacting object ball and before the top takes.
