develop on both sides
    Keywords: Joseki, Strategy

[Diagram]
Schematic

This isn't the result of a real joseki, but a kind of standard of comparison. How is this result to be evaluated, given that White had first play here?



  • The marked white stones mean that White has a good base for each group.
  • The marked black stone means that Black has escaped into the centre, as well as taking the corner.

From the point of view of the whole board position, White's two well-developed groups are the most important feature. In the global picture, getting established on both sides should outweigh Black's corner profit and sente.

There are many joseki variations with comparable results, especially with the 3-5 point pincers. In those one expects to find that one of the two side groups is weaker than in the diagram.

Allowing the opponent good development on both sides isn't really an acceptable result in joseki. The player taking the corner is in interested in making the pincer (or double kakari) here look like it might be an overplay.

Two-space pincer

The purpose of Black 1 here probably is to develop on both sides. White must now consider carefully whether playing White a, Black b, White c is good enough. If not, a pincer in the direction of d must be thought about.
