Ko 1: black's mistake  

hnishy: B5 at W6 captures the four White stones, doesn't it?.

xela: I've added a diagram later to show this variation.

kmr - yes, it looks like ko is not possible to achieve this way. After 5 at 6, white cant save four lower stones. White is dead.

Black's correct response: no ko  

If black plays B5 here, then the white+circle stones are captured
