This paper starts out with a vague introduction to static evaluation.  A lot of
what he says seems true to me, but he doesn't footnote and he makes a few
conclusions that seem to come from thin air.

He says that a static eval is named because it evaluates states.  I hadn't
realized this.  I thought that "static" in this case meant that pieces don't
move in a static eval -- they are static, which means "not moving".  But I don't
know -- I didn't read it anywhere -- and he doesn't footnote his assertion.

He then kicks into high gear with a section that suggests that the evaluation
can be improved by determining more complicated relationships between pieces, in
an effort to increase the level of "mathematics" involved.  He uses a lot of
jargon and gives no specifics about anything, although there are a few example
positions chosen that show that pieces do attack and defend each other on a
chess board, and that it's possible to define checkmate by using intersections
of attacked squares.

It's not always possible, by the way.  Sometimes it is possible to be checkmated
even when the king can reach squares that are not currently attacked.  I leave
the specifics unstated in case someone wants to write a paper about this.
