Capturing Race Exercise 3 Solution
   

[Diagram]
Diag.: Ko for life

This gives us a ko...


[Diagram]
Diag.: Better

...but this gives us a snapback, and Black is defenseless (unless there's another option for Black 2 that I don't see). And since the problem page is referenced by Snapback Workshop, my hunch is that this is correct.

-- Scartol


[Diagram]
Diag.: Better

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

[Diagram]
Diag.: Another way A

How about this?

After 3 Black may respond at a or b. If Black responds at a, White captures at 3. If Black responds at b, White captures at a.


[Diagram]
Diag.: Another way B

If Black responds to White 1 at 2 (or a), White captures at 3. At that point the marked stones are dead. Black can't prevent White capturing them.

--Bisqwit


[Diagram]
Diag.: Still a ko

Nice try, but Black 2 can still create a ko this way.

--unkx80

It creates a ko threat indeed. If Black can't find a larger threat somewhere else on the board for White, he loses the battle. --Bisqwit

Newcomers to tsumego like to ask this question. I direct you to read Conventions in Life and Death instead. =) --unkx80
