Actually, I would prefer a general synopsis of how, when, and why as opposed to code. I am trying to combine my SEE functionality with a set of square control eval functionality, so I want it for scoring as well as move ordering. I wanted to know if people kept track of battery pieces; if they use it just near the root (ala Crafty's Enprise function), everywhere, or only on the leaves, etc. KarinsDad :)
