The Art ofCapturing Stones Sacrifice Techniques

Preface

In go there are various capturing techniques which requiresacrificing stones. Most beginners fail to see these moves. Evenadvanced players might overlook them if they don'tpay attention.Mastering these techniques equips aplayerwith powerful weaponsfor both attack and defense. In addition, the training in visualizationthat we get by studying these tactical finesses will serve us ingood stead even in more straightforward positions.

Generally, there are the following three kinds of sacrificetechniques, each of which is devoted a chapter:

1) Under the Stones (Ishi-no-shita)- This spectacular techniqueinvolves allowing your opponent to make a seemingly decisivecapture in order to set up a recapture, thereby forming an eye,taking territory or forcing ko.

2) Killing Oversized Eyes (Nakade)- With this technique youalso sacrifice some stones in order to then make a placement at thevital point inside the resulting oversized eye. In most cases thisreduces the nakade to only one eye, but in certain positions youcan convert the whole nakade into a single false eye. You are nodoubt familiar with such unsettled shapes as the pyramid-four,bulky-five and flowery-six. However, if the defender's positionhas certain defects, you can even sacrifice larger shapes which arerelated to these basic patterns.

3) Other Sacrifice Techniques- Concerning various ways ofusing throw-ins to force your opponent into shortage of libertiesor make false eyes.

This book provides thorough training in the three types oftechniques listed above. By working through the followingreading problems, you can practice these skills and improve yourlevel of play.

Continuation- Black has hoped tomake life by capturing the four whitestones, but white 11 finishes off theentire group.

CorrectAnswer- The atari at white 1is inevitable, but the descent to white 3is an exquisite play, forcing Black todescend to 4. White then destroys aneye with 5 and Black is dead. IfBlacktries to resist by capturing the threewhite stones with 8, White increasesthe sacrifice with 9.

Correct Answer- The connection atwhite 1 and the cut at black 2 are bothnecessary. White 3 is a tesuji. WhenBlack plays atari with 4, White feedsone more stone, forming an under-the­stones shape to make life.

Tricked- If White plays 3 hereinstead, Black has the tesuji at 4. IfWhite captures the two black stones,Black throws back in at the markedstone killing the white group.

Correct Answer- White 1 occupiesthe vital point. If Black blocks at 2,White plays a diagonal move at 3. Theconnection at black 4 is forced. Whitefeeds in stones with 5 and 7, allowingthe black capture at 8.

Continuation- White plays atari at 9.Black fails to t2rm two eyes and isdead.

Failure- If White uses 3 to cut hereinstead, Black takes away a whiteliberty with 4. After the atari at white5, Black starts ako with 6 and 8. Whitehas failed.

Failure- IfWhite captures the markedstone, Black makes a hangingconnection at 2. With the moves to8,White tries to pull something off, butBlack has effective counters.5 connects at the marked stone

The Art ofCapturing Stones

Answer- White hanes at 1 to probeBlack's response. Against the hangingconnection at 2, white 3 is an effectiveplay. Through II, White captures someblack stones and makes life using theunder-the-stones technique.

Variation- If Black blocks at 4,White links upat5. AfterBlack'shaneat 6, White throws in at 7 forming a ko.This ko is also a heavy burden onBlack, therefore one shouldn't rushinto it recklessly.

Reference Diagram- If Blackconnects at 2, White draws back at 3.Black has only one eye in the comerand loses the capturing race.

Failure- If White hanes at 1, Blackjumps to 2 making miai of a and b.White has failed.

Failure- White tries the placement atI instead. Black blocks at 2 andWhite makes a diagonal move.Both sides block at 4 and 5respectively. The black con­nection at 6 makes miai of 'a'and 'b', so White collapses.

Answer- Peeping at 1 is thecorrect answer. White blocks at2 and Black extends to 3. Whitecaptures at 4. Black throws-inwith 5 at 3, and White capturesat 1 with 6. When Black peepsat 7, white 8 is a mistake. Blackplays a diagonal move at 9 linkingup to the outside. White hasbeen annihilated.5 throws in at 3 6 captures at I

The Art ofCapturing Stones

Failure- Turning at black 1 looks

natural but is a mistake. White has no

trouble reducing Black's eye space to

the dead flowery-six shape.

Correct Answer- The jump to black

1 is the correct move to prevent White

from creating a dead nakade shape. If

White connects at 2, Black descends

to 3. Against the white cut at 4, Black

connects and plays atari on White,

making life for the group.

What will be the outcomeof the capturing race inthe corner?

133

Page 67: The Art of Go Volume 2

134

The Art ofCapturing Stones

Correct Answer- White's turn at 1 isclever. Black must block at 2 andWhite makes a hanging connectionwith 3. Although Black can capturethe white stones in the corner, aflowery-six shape is formed, and Blackis dead. If White plays 1 at 3, Blackplays at 1 and lives.

Failure- IfWhite exchanges 1 for 2here first, Black still manages to cap­ture the white group, but capturing oneextra stone formsa liveshapefor Black.If White plays 3 at 4, connecting outhis 3 stones, Black cuts one spaceabove 3 and lives.

The Art ofCapturing Stones

Correct Answer- Black gets a ko

with the attachment at 1. White jumps

to2andBlackhanesat3. When White

extends to 4, one correct response is

for Black to press along with 5. White

connects at 6 and Black captures twostones at 7.

Continuation_ White throws in at 8

and Black creates a ko at 9.

AlsoCorrect- Playing atari withblack

5 also forms a ko. This is a more

straightforward approach.

White failure- White hanes at 2 in

reply to the attachment at black 1.

Black plays atari at 3, and after White

connects, cuts at 5 trapping two white

The Art ofCapturing Stones

CorrectAnswer- Black I is the vital

point. White descends to 2 and Black

draws back at 3. This is followed by

the extension of white 4, and the block

at 5. After white 6, Black extends at 7.

White plays atari at 8, Black counter­

atari at 9, and White captures at 10.

Continuation- Black recaptures at

black 13, a ko is formed.

Failure Black clamps at 1, inducing

white 2. The placement at black 3 is no

longer effective. Through 8, White isalive.

Failure- If Black plays atari at 5 in

reply to the extension at 4, White

makes lifewith 6, giving upfour stones.

Variation- Blocking at 2 in reply to
