Discussion about R16,P17,Q15,M17,Q17,P16,R12

Not that good for white right???

( FYI @mark5000 )

It is fine for White. Not good for Black if anything.

A piece of traditional theory is that the White group is overconcentrated. It is true and still modern theory but Black also is spending a move to reinforce his corner and that can be a bit slow in joseki situations.


Doesn’t seem like a lot of profit for black to have given away sente…

It is an interesting position.

Here is a simple work-up of this position by an amateur dan that might contribute to the discussion.
