3-4 point high approach outside contact, tsukehiki extend up

Tsukehiki, White extends into the centre

The intention of W6 is (quite obviously) to build influence toward the center. White is however granting Black quite a large corner territory.

Joseki

The joseki continues with B1 through B7 (it is very unlikely that Black will play tenuki instead of cutting; W2 at B7 is a fighting move only available when White is already strong to the right).



Black takes the corner territory, White gets influence towards the top and the center. Clearly the cutting point at a makes an important ladder relationship, now.

White presumably thought about this ladder before choosing this variation, with W6 in the first diagram: making this a ladder strategy.

[Diagram]

Sente? (Black 3 tenuki, Black 9 connects)

B1 instead of B5 from the previous diagram might seem better, taking sente, but if Black actually does play tenuki, W4 through W10 gouges out Black's corner.



Taking away the corner territory (and even the eyespace) is larger than a black move elsewhere would be. (See though tenuki is always an option.)
