Hi Fllecha,

Possible -- you have to know your shape has a weakness at C11,
so as long as you can handle it, it's OK.

R2 hane. R2 is very big because the two groups at the lower right
corner are in a contact fight! At that corner, whoever first gets eye space
and a base will have a very big advantage (settled),
versus the opponent's group which lacks eye space or a base.
R2 is very big. The local move is not o6. It is R2.

W gets this huge shared vital point first.

Again, you start a contact fight and then you ignore it,
and tenuki, like

.

W can capture this

stone -- How ?

This is a wedge, and it fails to split W.
You get a bad shape here if W replies a certain way.

If W simply connects at F9, you get a bad local shape,
and your

wedge has no meaning.

is a very common, standard mistake at these levels:
it simply fails to do what you want: to split W.
It's bad.

W can live very easily. Can you find a way (or two)
to make life as W ?

If you thought W was almost dead at

,
then why didn't you try to kill it ?
Again, why did you ignore a local fight and play tenuki ?

E11.

Homework: instead of your move o9,
if Black pushes at B12 now, what is W's correct local reply ?
If B pushes at B12, and W ignores it, then what is B's local follow-up ?
