The main line

If the ladder works for White, (s)he can play b to keep things relatively simple. Otherwise it's off to the complicated variations with a.

KISS

HolIgor: B8 seems to be a large yose move. I would not play it in the fuseki. After ponnuki white is almost alive, so the attack with 8 does not seem to be severe.

mgoetze: Uhm, it seems to me that W7 threatens to capture B2 and B4... but I haven't had much sleep...

HolIgor: Yes, you are right. White can capture in gote, but black is alive in the corner, so this is just big yose. B8 is a mild attack on the white group though. In some situations in may become sente. Then it is very good. Build territory while attacking.

Getting there...

Last chance to keep things relatively simple with a. Otherwise, b leads to the taisha five-way junction. The rest of this page will deal with a.

Rather simple

But maybe this is too simple for Black...

Ko!

...so he could play like this instead. White W3 at d is called "cowardice" by Kogo's Joseki Dictionary. I bet Kogo would be quite the coward here if Black had some good ko threats...

Anyway, Black continues with a (soft), b (medium) or c (I will destroy you with this ko! Bwahaha!).

HolIgor: There is no ko-threats in fuseki. Even if black wins the ko by allowing white to make two moves in a row somewhere else, white 3 stones are not dead yet. Black's profit is large, no doubt about it, but it is difficult to say if it is large enough. This is a dangerous ko.

Dieter: Since White will take first, I think the main argument for not starting the ko is that it will be difficult for Black to find a ko-threat compensating for having rendered two stones useless. White will simply not allow Black to take back the ko.
