Splitting Move


Chinese: 分投 (fen1 tou2)
Japanese: 割り打ち (wariuchi)
Korean: 갈라치기

A splitting move is a move on the side, splitting two distant opponent configurations, leaving the possibility to extend to one side or the other.

Also known as a wedge.


Splitting move  

If Black approaches (either point b), White can extend (to either point a). The two extensions are miai.

Another example

A different orientation of the shimari  

Black will want to approach at either b or c, and white will extend at c or a in response.


  • A move on the side, between enemy positions, leaving no room for an extension, is more generally referred to as an invasion, although there are invasions of frameworks that include the possibility of an extension.
  • A move between two enemy stone is called a wedge, although the term wedge may sometimes be used for a splitting move.
  • Modern AI generally do not like this play early in the game. Also, responding to an approach is by no means necessary.
