One-point jump

Jumping out with W1 is the most common answer to the tight pincer BC.

The answer at a is the standard play here. At b is the only real alternative: it is steady, and Black can hope then to develop on both sides.

Up onto the fourth line

To answer with B1 shows consistent, natural aggression. White has to find some way to deal with this play other than pushing at the circled point.

Noam? What is wrong with pushing at the circled point above?

The two major answers for White, at c and at d, have varied in popularity over recent decades. To play at d usually allows Black to take sente. On the other hand to play at c can mean large-scale fighting. Just recently the pros have been preferring c.

Inducing play

After W1, starting a new group, B2 is just about forced. Then W3 is expected.



One can explain this sequence: W1 is an inducing move, setting up W3. It also obstructs a black extension along the left side.

Main line

Next B1-B5 is the main line continuation. Black may instead try B1 at x, to trade away the pincer stone.

Continuations

After that, White has a choice of way to play: at the square-marked point to fight on the left side, or at one of the circle-marked points to attack on the upper side.



There are many variations on the way to this position, though.

A modern line

The variation with W1 these days is followed by B2-W3. Black will play B4 at once, but can leave follow-up moves here for a little while.



Black takes territory and sente. White was playing this way 15 years ago; but now the line above is seen again.

Steady for Black

If B1 on the third line instead, White can settle easily with well-timed kikashi W2, W4 and W6.



This allows B9, developing on both sides. Black has quite a low position, though: this isn't suitable in the context of a large-scale plan.
