4-4 point low approach three-space high pincer

Three-space high pincer  

This pincer has perhaps dropped back a bit in terms of fashion.

White's common reply  

White's most frequent reply is the low double kakari here.

White's other replies  

White's other common replies are a, tenuki, and three other kinds of double kakari:

• The high approach at b;
• The distant high approach at c;
• And the distant low approach at d.
  

The latter two c, d are more often seen in 4-, 5- or 6-stone handicap games, where White wants to approach the next handicap hoshi stone in the lower left after Black re-acted in this corner.
Because c, d are further down from the top left hoshi, they are more connected to that extension to follow.
