Solution

The objective of this problem is to introduce the technique of W1, which captures the black+circle stone. It also ensures the life of the White group.

[Diagram]

Solution - main line

If B2 pushes in, then W3 is the standard second line capture, which ensures an eye for White.

[Diagram]

Solution - if black cuts

Black attempting to cut with B2 leaves him with a capturing race he can't win.

[Diagram]

Failure

Simply connecting with W1 leaves a play open at B2, making miai of a and b for connection, so we can't capture the stone.
