Attach wrong side

W3 is somewhat like a hamete, and is played when Black has an extension at black+circle or similar, and the left side has lower value. By exploiting Black's fear of crosscut, W3 aims to make Black's wall face the wrong direction. Note that if W3 is played at a, then Black would have blocked at W3 (c.f., 4-4 point one-space low pincer invasion, block), so White tries to preempt this outcome.

White's desired outcome

Usually White's desired outcome is for Black to play submissively at B1. Then W2 to W8 is joseki (c.f., 4-4 point one-space low pincer invasion, interception), but Black's wall faces downwards instead of rightwards, and black+circle is in an awkward position.

Black's resistance

Actually, Black can hane at the 3-3 point. If W2 crosscuts, then B3 descends. This reverts to 4-4 point low approach one-space low pincer, attach and crosscut, and the black+circle stone should help Black in the subsequent fight.

Black's resistance

So W2 can choose to pull back and avoid a fight. So B3 connects and keeps the corner, while W4 makes a two-space extension. Now B5 can choose to immobilize the white+circle stone at a or to attack the White group at b. In most situations, this result entails a local loss for White, so this variation is at least playable for Black.
