White's tenuki

One of the most complex and interesting of tenuki joseki is met when White ignores BC here.

Black's plays

Black's main choices here are at a, to close off the top side, or at b, which can turn into a play for the left side.

Other plays known in pro games are Black at c or d.

Black's move at a

This is the common line in pro practice. After W2 the WC stone retains aji. White will extend in the direction of W4 after B3: there is a question of whether to hold back at p, and whether or not to play the White q - Black r exchange first. That in turn depends on the use White intends to make of the play at s, aiming at WC from the other direction.



All these possibilities come up in pro games. There is another way to play B3.

Variation

Black can play B1 here: but is certainly too thin to kill White: consider White's plays at the x points. This way of playing was tried recently by Yamashita Keigo.

Black's move at b

Black's other main move can set off a joseki-like sequence. With W6, a hard-to-find tesuji, White can escape confinement.

[Diagram]

Continuation

Black's other main move can set off a joseki-like sequence. With W6 White can escape confinement. This particular line has been played a couple of times by the colourful Seo Neung-uk.
