b2 seems to do the job!? am I right?

After Bb2 follows Wc2. Now white has a lot of eye space. I could elaborate on that, but the main variation would be as follows:
Bb2, Wc2, Bb3, Wb1, Ba6, Wa2. The last exchange can be reversed with the same result. White lives.
You have to do better than that. It's not even a ko!

I would have played Bb2, Wc2, Bb3, Wb1 then Ba2... is there urgency to play Ba6 ?!
