Three-Spaced Mixed Extension Joseki

The 4-4 Point Low Approach, Small Knight Extension, Three-Spaced Mixed Extension is a popular response to the Small Knight Extension. It is often played to develop a fast framework and emphasizes outside influence, but it can be easily invaded.

It is seen in a number of fuseki, particularly the Kobayashi Fuseki and in modern go with white threatening to build a moyo on the top.

Once White plays W3, this joseki is settled and it is an even result.

Professional players typically leave this position alone and tenuki until the middle game, during which Black may attempt invasions and reductions. White has a large follow-up with a one-space jump at the circle marked point.
