Light play example 2
  Difficulty: Advanced   Keywords: Attack & Defence, Shape

[Diagram]
Diag.: After the probe

This is one of the common sequences after the probe White 1 in Black's enclosure. How should White continue after Black attacks at 6?


[Diagram]
Diag.: White 1 is light

White 1 is light, because it doesn't place too much importance on the marked stones.


[Diagram]
Diag.: Black tries hard

Black here seems too interested in cutting White. After Black 5, it is clear that Black has bad shape. The cutting points at a and White 6 are both serious.


[Diagram]
Diag.: Black is too keen to capture

If Black concentrates on capturing White's two stones, White will be happy. The ponnuki with White 4 gives White good shape; and Black has a problem.

Black has changed the order of play by cutting immediately at 1. That goes against the 123 principle. In this case Black has no good way to continue. Black at b isn't interesting, but there is nothing better.


[Diagram]
Diag.: White plays heavily

White should be reluctant to play White 1 here, in order to connect together securely. This is heavier, and the exchange of White 1 for Black 2 is a local loss.
