4-4 point low approach

corner  

This gives an overview of 4-4 point low approach josekis that have a page (or several pages) on Sensei's Library. Note that some of the linked plays are not joseki.

For each continuation, a standard sequence is given (this is one of the more common ones, but need not be the absolutely most common one), and an overview of pages dealing with that joseki and its variations.

• Has this been described? What would be common white move after ? szabgab
• My understanding is that is more common when there was already a black stone part way down the left side, possibly as far as the star point. A two space jump to appears to be an expected continuation. 44PointDiagonalAttachmentLowCornerEnclosure#diag11, BQM360#diag3, and 33PointInvasion#diag6 provide partial discussions. mrand

tapir: This is extremely rare without supporting stones along the left side. For comparison look at the 3-4 point joseki below. It is somewhat similar, but unlike the 4-4 stone the 3-4 stone already closes the door to the corner. is the most common answer to approach to .
