No one here or at that link mentions whether they are talking about
Chinese scoring or Japanese scoring.  It seems that the there would be
a significant difference.  For insnance, if I wanted to score a
Chinese endgame starting with no code, I would probably write an MCTS
move generator that played the game to the bitter end and then score
it using simple area counting.  But you can't do the same thing with
Japanese scoring.
