computer-go: Superko rules and computer go programs

[Peter.Smith@xxxxxxxxxxxxxxxx]

I'm interested in finding out what kind of superko rules people have
implemented in their Computer go programs.

For terminology refer to Robert Jasiek's excellent pages around
http://www.snafu.de/~jasiek/superko.html.

So far I have tried to implement situational super ko but have been worrying
about passes.  There are pathological Go positions in which passes would be
illegal under a situational superko rule if passes counted as moves.  I had
been assuming that players can always pass.
