Clamp on the second line

Depending on the context (hinted at by the circled points), black can either resist at a, connect at b or even play c (but this leaves black+circle in atari after white a.) If Black can't resist the clamp is a big endgame play.

Can black resist?

To resist black needs to capture W3 directly or in a ladder. A net is not enough since black+circle+B2 will be captured then. (Alternatively, if black+square is very stable - more than in this diagram -, black may force once or twice and simply capture W1.)

Less direct White moves

Another thing to keep in mind when trying to resist with B2 is that White can just threaten to play a with W3 or circle for example. Such moves can often cary other threats too. All things considered black has to be very careful about resisting with B2.
