RTG Problem 38 / Solution

Sub-page of RTGProblem38
[Diagram]

The first move.

The first move is B1, no disputes here. But how to answer W2?

[Diagram]

Mistake.

The hane at B3 is a mistake. After W4 and W6, Black is dead with a bulky five or flowery six nakade.

[Diagram]

Solution.

The tesuji is at the 1-2 point.

[Diagram]

Variation 1.

Probably this is the easiest variation. White tries to kill by nakade, but Black lives by seki.

[Diagram]

Variation 2.

If W4 here, B5 blocks and lives unconditionally too.

[Diagram]

Variation 3.

Perhaps the hardest to see is this variation. To answer W4, B5 occupies the other 1-2 point, and wins the capturing race. In the Chinese book 围棋古谱妙手选, B5 in this diagram is described as an excellent move.
