86.6.172.124: Regarding: Large Avalanche (2005-10-12 00:12) [#115]

Under which circumstances would one prefer to play the outward turn rather than the inward, and vice versa?

-- Phlegmatic

The inward turn was invented so as to take the corner territory. The outward turn implies outside influence.

-- Charles Matthews

In many professional games I see white in the diagram above leave the joseki when black plays 1 in order to play tenuki. What is the reasoning behind this? What if black then cuts, what are white's options?

-- Kanin?

The reasoning behind it probably is to use the White stones as pure influence, a light configuration part of which, when cut, can easily be sacrificed. Of course, the sacrifice should be outweighed by the value of playing elsewhere and keeping the initiative. --Dieter
