At first I was like, hey, you don't have to find the liberty gaining move at K2 to solve it. Then I was like, ah, yes you do... I think it's harder to find white's strongest resistance than it is to find the right move for black...

It's a tough problem, obviously, but SmartGo seems to have a lot of awkward life and death problems. It says you can capture those stones, but if you play it out further than SmartGo allows, B clearly dies. But then again, this is a 3k problem so maybe it's just beyond me. But, I couldn't figure it out. But, you solved it right according to SmartGo, by the way, so you've earned 6 Club Points!

But I don't understand how it captures. It seems like B dies in that situation. Keep in mind, I'm only a 9k, so I'm probably missing something.

Does that help?

Now I understand! Thanks. Sorry, I guess I wasn't seeing the whole board clearly, and was only focusing on that one little area. I hadn't even considered the right side. Thanks for clearing it up!
