AlphaGoJoseki/KobayashiLine

A new continuation  

The marked approach move fell out of fashion, a or b being favoured instead, but White's continuation of 1 caused a re-evaluation of the position.

First idea  

AlphaGo likes to play the push through and cut to the standard response of

First idea  

This line was completely new in terms of ideas, the end result is acceptable for White.

Second idea  

The critical line is then this. Without the marked stone, is generally considered an overplay. Here though, Black finishes in a comfortable position.

Third idea  

This is one of the positions played in the game, which although favourable locally for Black, was not considered to lead to a global advantage since Black had invested so many moves locally.

Isolated Idea  

Considering only the joseki itself, AlphaGo suggests that the above continuation is normally the most promising.
