joseki choice
Choice of a joseki sequence, or between a number of possible variations in a joseki, in order to fit in with the overall situation on the rest of the board.
The books The Great Joseki Debates and Whole Board Thinking in Joseki cover this area.
Choosing the correct joseki in a corner, or one sensible variation out of many, can be considered as an aspect of direction of play.
Sinprejic: To that end (and with the strong hope that stronger players will help!) I'm going to start using this page to link to various joseki pages based on the strategic results. After doing a bit of thinking I believe that I can place the results of a Joseki into logical categories (Dan level players please tell me what you think!)
Here's the breakdown I'm thinking of...
Every corner has an initial inhabitant (except in strange games) That color will be called the "Resident Color" The second player will be refered to as the "Approach Color". Similarly, for joseki that are not symmetric (do not involve an approach/invasion on the 2-2, 3-3, 4-4, 5-5 diagonal) the sides of the corner can be considered biased toward the approach stone or the resident stone. Thus I refer to the "Approach Side" and the "Resident Side"
- Side to Side Split
- Retain same side as the approach
- Swap Sides
- Influence territory split
- Approach Color Gets Influence
- Complete Influence
- Biased Influence
- Influence Biased towards the approach side
- Influence Biased away from the approach side
- Resident Color Gets Influence
- Complete Influence
- Biased Influence
- Influence Biased towards the approach side
- 44PointLowApproachLargeLowExtension (When approach color does not connect)
- 44PointLowApproachTsukenobiInvasion (When resident does not block)
- Influence Biased away from the approach side
- 44PointLowApproachLargeLowExtension (When approach does connect)
- 44PointLowApproachTsukenobiPushIntoCorner
- 44PointLowApproachTsukenobiJumpAttachment
- 44PointLowApproachTsukenobiDiagonalIntoCorner
- 44PointLowApproachTsukenobiInvasion (When resident does block)
- Influence Biased towards the approach side
- Approach Color Gets Influence
- Criss-cross
- Four Stable Groups
- Approach Color Retains Stable Corner/Floating Center
- Approach Color gets Side Groups
- Weaker Group On Approach Side
- Weaker Group Away From Approach Side
- Response to Symmetric Approach/Invasion
- Take Symetric Influence
- Take Biased Influence
- Take Symetric Territory
- Take Biased Territory
- Others?
