Kanazawa Problem 10 / Solution

Black lives

If we have gone through the previous problems of this series, we will have developed a feeling for this kind of problem and instinctively look for two possibilities: the 1-2 point and the 2-2 point. Here, Black 1 at the 1-2 point is correct. The exchanged marked stones are an indicator.

[Diagram]

Continuation

If White can do anything, she has to prevent the eye at the circled point so she plays 2. After 3, she can only connect at 4.

[Diagram]

Continuation

As we know by now, capturing three stones suffices for an eye.


[Diagram]

Wrong (i)

Black 1 at the 2-2 point is wrong. White 2 gives birth to a bent four in the corner shape and Black dies.


[Diagram]

Wrong (i) variation

B5 is tricky, and W6 is the correct answer. If W6 at a, then Black plays at W6 and lives.


[Diagram]

Wrong (ii)

For the sake of repetition, taking a stone with Black 1 is wrong too, for White creates a bulky five shape with 2 and strikes at the vital point with 4. If you have been solving tsumego for a while, 2 and 4 are moves you even don't have to think about anymore.

Wrong (iii)

How about enlarging the eyespace with 1 here ? Well, that's perhaps not too easy to refute and demands some explanation, so I'll make it Kanazawa Problem 10b.


Go to Problem 11.
