Nursery Cannons

Tried a few more practice routines off Martins site. How the hell he manages some of these shots I don’t know, it’s very difficult to see the aiming point on some shots and to judge the pace. Tried the nursery cannons without any luck, got to 6 and 8 shots before completely running out of position.

There must be some trick to this, I have been trying to locate some book on billiards but I haven’t found anything still in print.
