4-4 point low approach, tsukenobi
The tsuke-nobi (or attach-and-extend) joseki is formed by the moves to in this diagram.
The tsuke-nobi itself is mostly popular among weaker players, but for stronger players it is still a good idea if Black wants to build thickness towards the left side, and does not mind giving White a position on the upper side. In other words, Black regards the left side as more important than the top. Often, but certainly not always, there will be a black stone around the marked point. After , White at a, b, c and d are all joseki.
In pro games it is now rare unless justified by the context: either Black getting a very efficient formation relative to the left side, or White getting an overconcentrated formation at the top.
