[Diagram]
Ko for life

This gives us a ko...

Better

...but this gives us a snapback, and Black is defenseless (unless there's another option for B2 that I don't see). And since the problem page is referenced by Snapback Workshop, my hunch is that this is correct.

Better

Actually my intended snapback is the kind in this diagram, but your solution is correct nonetheless.

Another way A

How about this?



After W3 Black may respond at a or b. If Black responds at a, White captures at W3. If Black responds at b, White captures at a.

[Diagram]
Another way B

If Black responds to W 1 at B2 (or a), White captures at W3. At that point the BS stones are dead. Black can't prevent White capturing them.

Still a ko

Nice try, but B2 can still create a ko this way.

--unkx80

As a ko this is better for White as she captures first (try to get first capture in a ko), but the snapback is naturally the correct answer. --Dansc
