wishful thinking

If white tries this W4, black lives because of connect-and-die. But white can do better.

alternative

hhw: Here's an alternative. After W2, a and b are miai for White. It seems Black may want to consider B2.

Still dead.

JoelR: Black cannot even threaten an approach ko with B5. W6 makes it connect-and-die.
