lists.gnu.org isn't talking to me right now, but I've skimmed through
the paper.  It contains a high-level pseudocode for strategic planning
of a Go-playing agent.  However, it unfortunately doesn't explain how
to implement the functions like influence() or how to efficiently read
out the sequences appropriate for its kill() subroutine.

>From what I remember when I first started digging into GNUGo, the actual
GNUGo's implementation might be actually very similar to what the paper
describes!  The trouble starts when one starts looking into the
"implementation details" and how to avoid the combinatorial explosion
of possible sequences.

I'd encourage djhbrown to look into the GNUGo general strategy code
(which is *not* just a general alpha-beta search) and consider why it
doesn't work that well in practice.  I have found debugging GNUGo's
mistakes a great educational experience in the fundamental flaws of
classic engines back then.
