Bob-me too.
A 3 rail kick practice setup: ob on spot, cb in mouth of either corner pocket at the same end. Attempt to kick cb 3 rails into ob to pocket it in the opposite corner pocket.(corner 5 system-ish).
Continue kicking 3 rails from where the cb lies, trying to nudge the ob into the corner pocket. Try to do it in least number of kicks. Note: gets tougher if 1st kick attempt moves ob toward original cb pocket, instead of toward the intended open pocket)
A helpful drill that gives good sense of the marriage of a well known system, adjusted for your own stroke, speed, and spin. It also shows the limits of where you can get on that last leg of the 3 rail path, while avoiding the side pockets.
Same but different:
OB on spot. CB frozen to rail adjacent to a diamond below the side pocket. Kick 3 rails, attempting to pocket ob in the corner connected to the starting point side rail. Continue kicking at the ob by returning the cb, frozen, adjacent to the same or different diamond below the side. (usually to the same diamond location for consistency).
In general-it's practicing a 'last option' escape-so it's of limited value.
But then, I like wacky shots.
