And a and b are miai.

Let's see if I can find a stronger defense:

We have miai again to kill.

Back to the same as the previous defense. Guess this is my solution.

One possibility from your variations - though I haven't solved the problem, yet:

I missed that. Black takes the ko first, too ... ah well. I just thought that was a cool spot to hit, and I'd be satisfied if I got this as Black in my own games. Now, to see who brings a better solution.
