RTG Problem 14 / Solution

Solution

Solution

In this problem, White has to jump down at W1.

[Diagram]

Main line

B2 seems to be the strongest resistance. But with the exchange of W3 and B4, W5 is the standard way of killing. After B9, if Black a, then White b, the white+circle stone works perfectly, so there is no problem.

[Diagram]

Variation

If B2 here, then W3 reduces the eyespace and proceeds to kill in the same way above. After W9, if Black a, then White b.

[Diagram]

Variation

After W3, Black does not have enough eyespace to live with two eyes. There is no problem with the connection of the W3 stone with the outside stones.



Failure

[Diagram]

Failure

With the black+circle hane stone, the descent at W1 no longer works. B2 and B4 is tesuji, so White can only create a ko with W5 and W7.

[Diagram]

Failure

White only manage to get a ko here.
