Corner co-ordination 2
    Keywords: Opening

Chikun's plan

[Diagram]
3-5 and 3-3

This is one of the less common side formations. If Black plays next at a the corner co-ordination of the resulting 'sub-orthodox formation' is reasonable (not great, perhaps, compared to the orthodox fuseki).

The press plan

Assuming White enters at W1 here, the co-ordination isn't brilliant if Black plays, for example, the pincer b. Black's chances of a framework on the upper side are limited by what White might do with the shoulder hit at c next. Black at b looks like the right type of idea with a 4-4 point in the right-hand corner.

Cho Chikun's play, in a number of his games, is to press with B2. This then assumes that the right-hand corner can take care of itself. In playing the press one has to bear in mind some large-scale variations leading to a pushing battle. See pushing battles in joseki 5.

The other formation

Thinking of the other arrangement, we get a formation rare in pro games (tried out a few times by Sakata).

Not so well co-ordinated

White can easily ignore this side.

Easy shoulder hit reduction

The reason is that W4 keeps the side territory down, even if Black uses B1 and B3 to build up a framework.
