Joseki of the week 11
Joseki of the week 11 looks at the 5-4 point, outside-attach and draw back joseki.
(takamoku-tsuke-hiki)
White plays a 3-4 inside approach, black plays the outside contact, white hanes under and black pulls back to 5 in Dia 1.
Diagram 1.
White 4 above is forced. White can play either a or b next.
Diagram 2. – - – - – - – - – - – - – - – - – Diagram 3.
White 1 in diagrams 2-3 allows black to cut on either side.
White gains extra thickness from the ponnuki in both cases.
In diagram 2, white continues with 7 at a or b.
In diagram 3, where black aims for outside influence, white can continue with a or tenuki.
diagram 4.
If white plays tenuki at the end of diagram 3, then black can play 1 and 3 in diagram 4.
However even if white plays tenuki a second time, the corner is still a ko at a.
Diagram 5.
white plays 1 above to ensure access to both corner and top side of the board.
Black no longer has the option to choose whether to take the corner, or influence on the top side.
However, white has a lower position than if white played as in diagram 2.
If there are any questions about the joseki of the week,
or if they are too basic/under-examined/complex, let us know in the comments!
