    Keywords: Joseki

The ogeima answer to the 3-4 point, high approach is rare.

Ogeima

Database search (gobase) in a 10x10 quadrant reveals two games with a, one game with c and three games with tenuki.

[Diagram]

a: Corner contact

The other contact play reverts to a 5-4 point joseki. The database search gives W5 at a or b.

According to All About Joseki, the downside to white+circle instead of the usual play at circle is that now an invasion by white at y is less severe because a black play at z is sente, which would not be the case with white+circle at circle.

[Diagram]

Tenuki

Professional play tells that if black plays tenuki, white's aim is to attack at b.

[Diagram]

Cutting contact

Cutting through the ogeima is not seen in pro play. The cross-cut W2-B3 is inevitable. Then White has many options.

[Diagram]

Simplest

The simplest idea is to strengthen the weakest stone in the crosscut. Even though white+circle is blighted, the corner is big and Black has no eyes.

[Diagram]

Atari

The atari doesn't look too good. Black gets a big corner and White's shape is troubled by a.

[Diagram]

Descend

The descent is not as sharp. Black is easier here than in the "simplest" diagram.
