3-3 Point, when does it work
Path: PleaseReviewMe · Prev: CGTLifePointsValues · Next: ExtensionFromAWall
Difficulty: Beginner
Keywords: MiddleGame, Joseki, Question
mat: I'd like to know which configurations of black stones allow a 3-3 invasion and which don't. Please continue this list! Blue Wyvern: Also, could people add the josekis if they know them? Somehow I always screw up invading a knight's move from the star point (hoshi) even though I am sure it is possible to live. mat I'd like to leave this page as an overview. We can have the josekis linked. Charles Matthews Beware of expecting answers that are too clear-cut. There may be a ko, and there may also be continuations that are messy, depending on circumstances on the outside.
This case is discussed at 3-3 Point Invasion and 4-4 point 3-3 invasion joseki.
For this case see 3-3 point invasion query 6.
This formation is called the "three crows". White has no chance even with some help from outside (white 'a' or 'b'). For this see 4435 enclosure #2.
See also TheSmallLowEnclosureIsSecure
The 3/3 invasion into the SmallHighEnclosure occurs e.g. in QueriesAboutEnclosureJosekis1. Forseeing whether or not white can live is beyond my knowledge.
See 364463Enclosure. --Dieter mat: a quote from there: "black can kill. But it is difficult" See 33PointWhenDoesItWorkContinuation1 for another continuation
Scartol: This is covered in 4463 enclosure 3-3 invasion and 4463 enclosure. mat In summary: black attacks with a and white may live after ko
See 4464 enclosure 3-3 invasion. See 33PointWhenDoesItWorkContinuation2 for another continuation mat: In summary (as far as I understood from the links), white lives, but it is not easy.
mat: I guess black can kill. Anyone stronger than me please comment...
I know this enclosure is supposed to be immune to a raw invasion without support by White, but how does Black kill? (See 364473 enclosure.)
