Beginner Exercise 60 / Solution

Sub-page of BeginnerExercise60

There are actually two solutions for this problem.

[Diagram]

Solution 1

The clamp at B1 is a tesuji for expanding eye space. If W2 at W4, Black can connect at B3 and the result is still the same.

[Diagram]

Solution 2 (6 at 1)

Black can also make a cut at B1. To save the three stones White has to play at W2. Subsequently B3 and B5 are a tesuji combination, and Black lives with B7.

Caution: Do not play B3 at B5: White can connect at B3 and Black cannot make the eye on the top.

Toey: Regarding solution 2, what will happen if White instead plays W6 at B7? Can Black still make two eyes on top?

unkx80: Yes, by capturing three white stones.

[Diagram]

White makes trouble

But suppose White pushes up with W2 first? That's suicidal -- Black just captures all the stones with a series of atari moves.. (I put this in for reference; I thought White could escape, until I made up the diagram. -- Scartol)


[Diagram]

Failure

B1 does not expand his eye space enough.


AGiss, unkx80.
