Variations of Our Solution (II)

VAR (L)

(Referenced by 193; 226; 228)


: ( 197)
Black connects his partial groups through the bamboo joint, threatening to capture two of White's stones.

: (A 392; B 408; C 413)
White chooses the point that she in principle occupies in our solution, too, giving atari on Black's single stone above. This choice will benefit White in the Capture Variation.
If White connects at , instead, she will gain the same result as with our solution - but only in the case Black will follow White so indulgent. Black's kikashi of results in a change in the order of moves then.
White might try to play at , instead, depriving Black of the guzumi. However, she will gain a result that is slightly worse than with our solution.
A tenuki e.g. with , instead, will also not benefit White. This is similar to the guzumi.

: (75 414)
Both sides continue with the "usual" path of our solution. Please remember that not playing the guzumi will cost three points locally.
Black might try to immediately continue with the Crosscut Sequence, with a move at , instead, and play the hiki of later, due to his just won liberty. In principle, this will result in a change in the order of moves with variations of Joachim's Ko-Semeai ( 225).

:
Please note that this move is gote. White is not forced to continue locally.

: (A 422)
White starts the endgame on the left side "early". Otherwise she might lose points, due to Black's earlier kikashi in the bamboo joint.


The Hanezeki Exchange ( - ) must be played earlier.

Here, White will gain one point by playing an unbelievable tenuki in the hanezeki in order to attack Black's upper left corner with a hane at .

Please refer to 503 for details why our previous order of moves was mistaken.

: (118 425; A 426)
It will not benefit Black to save his single stone in the upper left corner, with a move at , instead.

Neither will it help Black to concentrate on occupying liberties of White's group on the left side, starting with a move at , and let White have what she wants elsewhere.

:
It is not correct for White to peep at , instead. This will become a loss of one point, if she later captures both hasami-tsuke stones.

:
This is the position, before the mutual occupation of liberties begins. In the marked area in the top right corner, Black has 12 liberties () now, as many as in our solution at a matchable moment.

However, if Black's top right group eventually lives, White gained four points (, ). Thus Black will win the Capture Variation by only one point.

Black will win by one point.

///:

For the sake of reference we display the position after move in our solution. It does not matter that the first part of the Nakade Sequence on the left side has been played already. We have added the (there later played) moves, which result in the connection of Black's hasami-tsuke stones (/, /). Black's top right group has 12 liberties () in the marked area.

Please note that - in principle - Black played at here, instead of at (= Michael Redmond's kikashi), thus gaining four points of territory in the Capture Variation.
