NetExample11/Solution

First choice of net, and the weakness  

Charles White has a choice of possible nets after and . + looks to be best for shape, but one has to take into consideration the blunt . , as here, is a failure since escapes.

Making sure  

here certainly works in reply to . White would prefer this one to the right.

Too thin  

But White can't afford this: puts White in trouble.

Second choice of net  

The other way.

Try to minimise loss  

White really wants to be light here, so is always worth considering. Up to may be forced. White is doing very well in the centre.

Continuation  

[1] If White can survive this fight, this way of playing is attractive.

use the wall - take liberties (1)  

[4]tderz: taking another liberty with is attractive,
after all - use the length of the wall ! (that rhymes). (Charles Yes - I think this was my first thought, which I then forgot!)

For me it was a development too, I think dia (9) is a good technical, local solution - if the aim is to capture the cutting stones. I did not find it in first instance.
The real solution could be something else as making Sanrensei or another see-and-wait strategy.

use the wall - take liberties (2)  

tderz: what can black do with the 3 liberties a-b-c ?

use the wall - take liberties (3)  

tderz: Whether this is a threat to white , depends on the whole board position.

is a mistake, see dia (6) below. should be at .

use the wall - take liberties (4)  

tderz: playing light with is also often advisable -
all of the points p-q-r-s-t belong further possiblities.

looks nice at first, but is a simple mistake (black would cut at v immedeately),
it should be somewhere around u in order to avoid the sequence of dia (6) and protect the cutting point v.

use the wall - take liberties (5)  

tderz: seems safe but black can escape with d (as ) below
d and e are miai (yet only d works for black) -
only black b would lead to auto-atari.

use the wall - take liberties (6)  

tderz: this is understandable but not safe against a black escape either.

use the wall - take liberties (7)  

tderz: there is no ladder with at hence, black succeeds in cutting of.

White has got a wall with a filling - this is a great result, nothing to be ashamed of.
White has now invasion tesujis t or u at her disposal if she wishes too. And the game has just started!

If white could also protect against the separation it would mean that black had collapsed.

use the wall - take liberties (8)  

tderz: would it make a difference if there were some white stones ?
Could one induce them by a wedge before starting - a different - net?

Big Geta - use the wall - take liberties (9)  

tderz: now the cut at a cannot lead anymore to multiple ataris and a final escape.
In order to prevent black's escape r-s-t-u, White has to prepare directly after ( and in dia (10)) with the blunt looking exchange p-q (or could one try something stylish-looking as v, with the danger of discovering that things develop different).

If white hopes for the p-q exchange after the exchange -black r , it's too late. Then Black would connect to with s and capture the white group.

Big Geta - use the wall - take liberties (9)  

tderz: this looks even better - it seems to capture in sente by threatening d.
Attempts for escape a can be blocked by b.
Stylish b is simply countered by white a. Sometimes the inside hane f after black d, white e leads to results, but white here simply takes the penultimate liberty.

different strategy (10)  

tderz: different strategy - the wall is strong enough to survive even without (directly) catching the cutting stones.
In respect of the invasion points t and u in digram (7), and are however aji-keshi and not needed, because they don't contribute to catching the cutting stone.

Capturing sequence for white (1)  

Minue I didnt check if there are other ways to capture black. But for me, the following variation looks simple and clear way for white.

Sequence is rather long, but its course is quite straight forward, and does not have any other branches, so not hard to read and follow it with some caution.
