As somewhat of a billiards enthusiast, I stumbled upon this site a few years ago. The biggest result of this was the discovery of &quot;throw&quot; and the ways that it can come into play (both intentionally and unintentionally).  Once I learned how to control it, I started being able to make shots that I had once thought were impossible.<p>Many of these videos helped me to improve my intuitive understanding of the physics of the game, and made me a better player as a result. Thanks Dr. Dave!
