    @caranthir so under japanese rules it is no points? Ok, I took a guess after I put the seki on a kgs board and the estimator wasn't able to detect the seki and counted white as dead. Then either variation is same points.
    caranthir:
    Yeah, Japanese rules don't award points for eyes in seki. It has been said that this might be a historical remnant, a kind of "half a group tax" descending from classical Chinese rules which have group tax for every group, seki or not.

    I think in two of the variations they should play differently to make 2 eyes in the corner rather than each having one as under many rulesets this makes a 2 point difference
    caranthir:
    Under Japanese rules the result shouldn't change. Under Chinese or Tromp-Taylor, the defender gets two points for the (false) eyes. If stone counting is applied, we can observe that the defender would be able to play one extra stone inside one of their eyes but not both, and the attacker can play no extra stones so I suppose under classical Chinese (Tang-era) rules, the difference is one point for the benefit of the defender compared to Japanese rules. [d4rkm4tter: Interesting. Two false eyes vs no eye = seki with 2 point difference under japanese rules. I changed the sequences. ]
