I've hear this term thrown around, and understand parts of it, but I'm not entirely clear on what exactly this move is, from beginning to end.
I believe the finish, from an adjacent block, is:
- Ramp over your opponent
- Back-edit one side of the ramp. This both reverses the ramp, and splits it in half. The half-split isn't really needed; it's for speed: this edit is faster than rotating the ramp 180 degrees.
- Hit your shot--quickly :)
Is this all there is to it? Is there more, in the setup?
