Japanese Rule Sharpness
This page aims to provide a simple position in which Japanese Rules are “sharper” than Chinese Rules, where (as indicated in the article Sunjang Baduk Counting) a rule set ``R`` is considered “sharper” than another rule set ``S`` in a certain position if fewer moves are optimal in that position under ``R`` than under ``S``.

fills the ko with sente, threatening to kill Black with a throw-in at 4. If
throws in at 4, Black takes the ko and wins it. If White were komaster,
would fill at 4, and the ko would be a 1⅔ pt. White sente.
