Pick a Ko  

Now, black has a choice between securing the left and the right. If he secures the right, go after the left, and likewise, if he secures the left, play on the right as follows:

unkx80: This sequence from W1 to W5 is my intended solution, because white will take the ko first.

letsrock: The solution might not work in all cases. If B6 fills at W3 and black wins the ko on the left he can also secure the left group with b.

Anonymous: In either case white needs to win the ko on the undefended side...

If Black secures left (5 at marked)  

Any better ideas?
