3-4 point, high approach, ogeima
   

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.

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.

Corner contact

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

Tenuki

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