[computer-go] Problems in mixing rule sets

[Darren Cook]

I've been training from game records played in Japanese rule sets, but I
am using Chinese scoring. I was braced for obscure seki and triple kos
but the issues that are coming up are more mundane:

1. In Japanese rules when you have no ko threats you pass, then the
opponent connects. In Chinese rules you'd play a dame, and if none you'd
fill in a point of your own territory.
  This is creating a 1pt difference in final score. In at least one game
I have it makes the difference in who wins.

2. In some games both players have passed then noticed a ko that
should've been connected. When the opponent tries to recapture, it
creates a super ko violation.

The 2nd problem is rare enough that I can fix it by manually fixing the
game end to remove the human error.

For the 1st problem I believe there is nothing to be done. My current
thinking is to split off games that contain a pass move before game end
and make separate Chinese and Japanese game sets for just those games.
Just wondered if anyone had a better idea, or if there is established
practice for this.
