Enjoy!

All captures are made with red stones, which are immortal. A player may capture a stone or stones of either color, or both, with one play.

We don't know who we are; we don't know where we are.
Each of us woke up one moment and here we were in the darkness.
We're nameless things with no memory; no knowledge of what went before,
No understanding of what is now, no knowledge of what will be.

Not sure this problem belongs to "Improve Your Game". I propose a new chapter "Deviant Go". Why? Because I didn't remember Redstone as a form of deviant go so I started to solve Bill's problem as a straight go problem and I got confused because I got slowly convinced that it is clearly alive.
