I'll try to answer this, since I just got done spending hours fixing my own SEE.
The idea is to calculate the value of a capture without actually making any
moves. Basically, you count up all the attackers and defenders of a particular
square, and then look at what would happen if you made each capture, one at a
time, starting with the least valuable piece, and going through the most
valuable. You also have to bear in mind when you can stand pat (not make any
more captures). Sjeng's SEE code is an excellent model. Check out

Hope this helps! Andrew
