<p>White's connection and pincer sequence in another answer works well only if White has a stone (or stones) around the star point D16 in the upper left corner. Then, the 7th stone on J16 is both a pincer and an extension.</p>

<p>Otherwise, White should invade the upper right corner at the 3-3 point, r17 with move 5. If Black blocks at r 16, White will connect this stone to the kakari stone.</p>

<p>Good question.  White usually jumps into the corner in this joseki; if he jumps out he is ready to fight if necessary.  When Black peeps he is giving you a wall that you can use to counterattack his pincer stone.</p>

<p><a href="http://eidogo.com" rel="nofollow">eidogo</a> recommends W7, which denies Black a base on the side while being harder to press down.</p>

<p>Black jumping out to B8 leaves a weak point at <code>a</code>.  Note that the corner can still be invaded and that White might get to block off the right side.  How this develops will depend on the rest of the board, I think, but it doesn't seem bad for White.</p>

<p>Every now and again when I approach a corner, opponent plays 1-space pincer and I jump out, my opponent immediately peeps. This seems like <em>aji keshi</em> and bad shape, but I've been stumped as to how to really take advantage of it.

White's connection and pincer sequence in another answer works well only if White has a stone (or stones) around the star point D16 in the upper left corner. Then, the 7th stone on J16 is both a pincer and an extension.

```

More likely, Black will block at Q17. This captures the kakari stone on O17, but Black's stones are overconcentrated.

Either way, the White stone on O15 remains "loose," and in a position to cancel Black's outside influence.

Black jumping out to B8 leaves a weak point at `a`. Note that the corner can still be invaded and that White might get to block off the right side. How this develops will depend on the rest of the board, I think, but it doesn't seem bad for White.
