people do some adjustment in that case. Does that mean they
actually use Chinese scoring internally?

Yes. The recipe is:
- play as usual with Chinese rules,
- take a one-point security margin with respect to komi,
- pass as soon as the opponent passes.
You also have to be careful to score seki the Japanese way in the
playouts. This is the most difficult part. If your playouts don't
understand seki, then you can just ignore seki, or take more than
one point of security margin if you wish to be safe.
Yes, I can see that seki would be the tricky part. You need to adjust
somehow for (false) eyes in the seki, as they are not scored with
Japanese rules.
Other than that, I'd take a different approach:
- play out as usual. Instead of counting stones + eyes on the board,
you count eyes + prisoners + nr-opponent's passes during playout.
- don't count passes outside of playout.
I think this avoids having to take a security margin or require
passing as soon as the opponent does (although in practice that may
happen almost all the time). The seki-matter is the same.
Did I overlook something?
