Main line

Later, if B4, then W5 captures the B4 stone and lives.


[Diagram]

Wrong

Leaving out the hane enables Black to play hane himself. The most White can get out of it is to starting a (terribly disadvantageous) ko at a.


[Diagram]

Wrong (ii)

The throw-in at B4 and the atari at B6 will throw the entire black group into a ko.

[Diagram]

Wrong

White W1 here doesn't threaten anything, giving Black the time to make an eye false at B4.
