RTG Problem 13 / Solution
Sub-page of RTGProblem13

Solution

[Diagram]
Solution

The key is the descent at W1.


[Diagram]
Main line

If B2, the sequence of W3 to W9 is a fairly standard way of killing. Black dies of a bulky five.


[Diagram]
Variation

W2 tries to expand the eyespace but W3 onwards kill.


[Diagram]
Variation

If W2 makes a diagonal move, W3 can squeeze. B4 does not work here because W5 and W7 can turn the other eye into a false eye.



Failure

[Diagram]
Failure

This is a seki.


[Diagram]
Failure

This lives too. But B6 is an important move.


[Diagram]
Failure

The jump of W1 is too fanciful. B10 captures and lives.
