];B[pd];W[dd];B[pq];W[dp];B[qk]C[Part 2 of the discussion of the Chinese Opening. ];W[nc]LB[lc:A]C[Let's consider what happens when White continues by approaching the upper right corner from the direction of White's star point.

In Part 1, I discussed why a black pincer at A is not the best choice. Please click A to review. ](;B[pf]LB[pb:A][jd:C][kd:B]C[Black's one space jump is simple and the most common response.
 
White will follow up with A, B or C. Please click each to see these variations.](;W[pb]LB[qc:A][jp:B]C[Sliding under is a common joseki. Black has the choice to continue the joseki at A, or tenuki to expand at B. Please click each to see variations. ](;B[qc]C[See the variation.];W[kc]C[This is a common joseki. ];B[fq]LB[dn:B][jp:A]C[When Black approaches the lower corner, continuing to expand from the right side, White has two directions to respond.

First, a white pincer at A, or other pincers in this area, would prevent Black's continued expansion; click A.

Second, White could strengthen the corner by playing at B; click B.](;W[dn];B[jp]LB[lp:A]C[Black's making an extension to bridge across the bottom side is a traditional way of playing. There are other options, including recent inventions such as extending all the way to A; I couldn't believe my eyes when I first saw this move, and I will discuss it at another time.];W[po]LB[qo:C][np:A][qp:B]C[Now it seems urgent for White to approach the lower right corner, because allowing Black to get this same move would help Black secure both sides.

White's one space high approach is traditional. Black has two directions for attacking this white stone: a knight's move at A,, and an attack from the corner at B or C. In this part of my introduction, I discuss A.](;B[np]C[This is the most common attacking move. It will help Black to secure the bottom side. ];W[qq]C[White's attaching to the corner stone is the joseki.];B[qr];W[qp];B[rr];W[qm]LB[qk:A]C[Here, White only has a one space extension to make a base, Ideally, White would want to extend at A, but Black is already there; this is the power of the Chinese opening, making a plan ahead of time to achieve this effect. ];B[nn]C[Black jumps to attack White's group and further protect the bottom side. ];W[om]C[White jumps out to escape.];B[on]C[Black pushes here to reduce White's potential eye space.,];W[pn];B[pl]LB[pm:A]C[Peeping attacks White's eye shape.

It looks natural for White to connect at A to protect the cut. However, this would be wrong; click A to see why.](;W[rk]C[White's attaching under is the good move. See the variation.];B[rj];W[rl];B[qj]C[Black connects to protect against a cut. ];W[pm]TR[rk:rl]C[Now White connects, but this time White has a live group thanks to the two marked stones on the second line. This result is considered fair for both players. ];B[cf]C[Black moves on to another big area on the board. 

[End of Part 2 of Feng Yun's Introduction to the Chinese Opening.\]])(;W[pm]C[Simply connecting would be wrong.];B[rl]C[Black would attack White's base, leaving White insufficient space to make two eyes. So, then White has to escape to the center. ];W[nm];B[mn];W[nk];B[pi]C[Black, by attacking, secures both the right and bottom sides. This is a good result for Black. ]))(;B[qp])(;B[qo]))(;W[jp]LB[ip:A][hq:B]C[Other pincers include a two space pincer at A, and a one space pincer at B. 

I will discuss these pincers another time.]))(;B[jp]C[A tenuki from the joseki to expanding the moyo is a creative way of play, ];W[qc]C[White naturally wants to take over the corner.];B[me]C[Black could continue expanding the moyo with a move up high on the 5th line. This is not a common way to play, but those who love a moyo game may want to consider it. ]))(;W[kd]LB[fc:A]C[This two space extension to make a base is very popular. However, this leaves Black the option of an approach at A to White's corner, where Black would still have space to make a two space extension.];B[fc];W[ec];B[fd];W[df];B[ic]C[Black can settle a group here comfortably with a two space extension.  ])(;W[jd]LB[lc:A]C[A three space extension is a well balanced move to bridge toward the top left corner. However, Black will have an invasion later at A.]))(;B[lc];W[qc]LB[pc:A][qd:B]C[White will invade the corner. Black has two choices: click A and B to see these variations.](;B[pc];W[qd];B[pe];W[pb];B[ob];W[qb];B[oc];W[qf]LB[qk:A]C[Locally this is a joseki. However, after White jumps out at White 10, you can see that the black stone marked A is not in a good position. Therefore, it is not a good option for Black. ])(;B[qd]LB[qk:A]C[Black blocks in this direction to work with the stone marked A. See the variation.];W[pc];B[od];W[nb];B[me]LB[pj:B][qk:A]C[This is the joseki. However, the black stone marked A is too far from the upper corner, leaving White a perfect reduction move at B.
