3-4 point, high approach, ogeima

    Keywords: Joseki

Fired off by the amateur fuseki 2 discussion, let's discuss this ogeima answer to the 3-4 point, high approach:

[Diagram]

Ogeima

dieter: I think a, b and tenuki are the options to assess. Database search (gobase) in a 10x10 quadrant reveals two games with a, one game with c and three games with tenuki.

[Diagram]

Cutting contact

This sequence looks kind of forced. Now, can White play a ? The database search seems to support the idea that this is unfavourable for Black.

KOKIRI - the numbering here is messed up - i think this is what you mean?

[Diagram]

how about...

kokiri: this looks fairly natural to me and good for white. a if W6 fails to capture the two stones might be a bit overconcentrated and might give up the corner, 'm not sure

[Diagram]

how about...This!

Klaus: yes, white is strong, but black got more points. Fair?

kokiri - this seems natural to me and a fairly even exchange

Dieter: Maybe the result is fair but the exchange is not. I believe both B1 and W4 are mistakes. W4 should be at B5. Hence B1 should be elsewhere, notably at B5.

kokiri - ok - this looks like a case of playing 3 rather than 1-2-3. i will think about it.

Bill: I think the result favors Black. White is overcrowded while Black has a large territory.

Corner contact

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

[Diagram]

Tenuki

Does White have severer plays against B1 than with W2 keima at a ?

Andre Engels: Professional play tells that if black plays tenuki, white's aim is to attack at b. If white does continue here, the sequence in 'corner contact' above can be considered some kind of joseki.
