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 (ii) (cont)  

If White connects the ko at W3, the atari at B4 blows the eyeshape away. If White doesn't, a black capture at B3 continues the ko.


[Diagram]
Wrong  

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