Sorry, this page is not finished. I am putting up some diagrams showing simple principles of cue ball positioning and some info I wrote a few years ago about double hits. The diagrams are completed. I did them a while back to explain some things to some friends. It's mostly a matter of adding some organization to all of it.

This is something I wrote trying to explain the salient issues involved in a double-hit.
