Choshi Examples

  Difficulty: Expert  

Example 1

White reinforces with choshi  

This example comes from Atsuku Utsu (To Play Thickly), by the editorial staff of Igo magazine, p. 116. White was Takagawa, Black was Kitani.

W1 "reinforces the top side with choshi."

Continuation (i)  

White plays W5 to begin to settle the white+circle orphans. Note that B6 is also played with choshi.

Continuation (ii)  

White plays kikashi with W11 - B14 before playing W15. Now the game depends upon Black's attack on White's central group.

Example 2

Fujisawa Tesuji Dictionary  

By taking profit in the corner with W1 White considers the exchange of B2 for W3 choshi, but in reply, W3 provokes B4, also choshi. (i.e. White shouldn't play this way.)

Example 3

An invitation  

This example comes from 21st Century Go, vol. 5, p. 229, by Go Seigen.

In the real game Black extended to a, but Go Seigen likes the enclosure with B1. B1 invites W2, and then Black follows with B3, for choshi.

Just right  

If now W4, B5 and B7 are just right.
