The Downward Thrust
    Keywords: Joseki

I haven't seen this before, so I don't know if this is a real joseki or not. Or maybe it is a new one? Does anyone have any thoughts on different possible variations, good situations to use this? --BlueWyvern

Downward Thrust

This is basically the opposite of the upwards thrust from the 3-4 point. It seems like a or b are the likely white continuations although c seems like it may be possible if the ladder is favorable for White.

Possible continuation?

Shared profit?

More continuation fun...

White takes the corner?



BillSpight: Interesting idea! :-)

Black corner

Black 4 at 5 is too passive. White plays kikashi with White 5 - Black 10,

and extends to 1. The marked black stone looks a bit out of place.


[Diagram]
Big White corner

Black 2 and Black 4 work with the stones Black already has, but White gets a big corner. The exchange of the marked stones favors White a bit.


[Diagram]
Black influence

White 3 at a strengthens Black needlessly. After Black 4 Black is thick, but a bit overconcentrated.



HolIgor: But the question is not whether this is playable. The question is if this is the most efficient way in the situation.

Black can choose a at move 2, going for thickness. With the downward thrust Black allows White to make the choice.
