[DVbS78rkR7NVe]

Maybe I should use colored paper instead of pure white.

Black to play.

Cool board!

my tsumego answer

A2 seems like the right spot. I think B2 is seki.

I think it’s a Ko (advantageous for Black) ?

This is what I have in mind:

A2-B2-A4-A1-B1

Tsumego reply

A2-B2-C2

Nice picture + tsumego = bump

I don’t see any reason why A2 doesn’t just live.
