Attach-block

    Keywords: Joseki, Shape

Attach-block combination.

[Diagram]
Attach then block  

This sort of pattern: B1 is a contact play (tsuke) and B3 a block (osae). This is a territorial way to play.

White normally plays W1 immediately to give Black the so-called hat shape. Then White has to deal somehow with the two cutting points a and b. Neither side has perfect shape here, therefore.



Before W1 is played, there was some aji at c - which disappears after B2. Black can play attach-block as an attacking technique, to make White heavy. When White is defending a group, the atari play W1 is probably something that White must play.

See attach-block joseki.
