I've looked at this, but I can't see how B captures those stones. 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!

Could you show where you're getting stuck? Chew's sequence looks right to me...

It was right. That's the answer SmartGo displays. 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.

Why do you say "It seems like B dies"?

Therefore, black's stones will all live after he captures the four white stones on the right, and white's stones will not be able to get eyes, therefore they are just dead.
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!
