Path: BigQuestionMark · Prev: BQM137 · Next: BQM139 TJ: Something I point out to beginners, which seems often taken for granted as known, about forming eyes. If a group has more territory, it is more likely to be able to live if invaded. Whether it can live or not depends on shape. If the shape is seven points of territory or more, it cannot have its eye space compromised with correct defense, and can make two eyes.
Less than seven points, it depends on shape of the territory surrounded. So, a good starting point for beginners is to learn the status of the territory shapes between three and six. That's not such a huge task, and makes all that life and death stuff you keep hearing is so important a lot more comprehensible; not to mention stopping you from considering attacks that just won't work and freeing you to look elsewhere, and helping you stop wasting time with over cautious defense of perfectly safe groups in your games. On SL, check out Eye Space to learn all about these important shapes. Further ramifications directly deduced from this once the shapes between 3 and 6 are understood: Problems of Life and Death, both as exercise and within games, boils succinctly down to: Can a group can be cut off, and the territory it holds reduced to less than seven points of a shape which can be killed (death)/can such an occurance be avoided, or made to depend on the outcome of a Ko which will give the group life if won or give the player compensation for the killed group if lost (life). Capturing races are just a form of the same thing in which two opposing groups are trying to live/kill each other at the same time. Is this a good concise way of talking about what eyes are all about, and how to learn about them? If this is off topic, or is better stated elsewhere, or just too long winded, forgive me...I'm new here.:) TJ: Given the discussions can I re-edit this to read something like:
And then carry on with the rest pretty much as is? [1] See Ten point Eye - Possible Seki, Nine point Eye - Possible Seki and Eight point Eye - Possible Ko Path: BigQuestionMark · Prev: BQM137 · Next: BQM139 This is a copy of the living page "BQM138" at Sensei's Library. ![]() |
