4-4 point one-space low pincer invasion, interception, hane underneath
    Keywords: Joseki

[Diagram]
Hane underneath

B6 hane here is probably a special plan, for example if Black has strength in the direction of a. This play looks for more territory, but the white pincer stone remains as a more serious problem; so Black cannot claim a thick position.

Settle quickly

One variation from pro games is this, with W3 allowing B4 at the key bulge point. W5 is for immediate life, leaving Black to worry about WC.

W5 tenuki is also seen here, with a different feeling.

Tenuki

Here White makes a ponnuki, and has sente once more.

Velobici: can White tenuki at this point? Assuming a black stone at a (as we assumed in the first diagram), it would seem that White must immediately play to support the four stones that comprise the ponnuki.

Steady joseki

Assuming no black stone at a, White can also play steadily with this W3 and W5, leaving the question of the aji of the marked stone for later. Black may be able to take sente, but White shouldn't omit W5 because Black b is severe.
