C[B1, 3, and 5 is the familiar low Chinese opening.
];W[jp];B[cn];W[mp]
;B[np]
C[B9 is usually played at Q5, but the attachment at 9 is quite
popular in Korea at present.  New continuations have been developed
recently because of all this study.
];W[no]
(;B[op]
C[B11: See variation.

(;W[qp]
C[W12 is nicely timed. If White connects at N5 instead (the old
way), Black would respond at Q6. See variation.
]
(;B[mo]
C[B13:  See variation for B13 at R3.
];W[lp];B[nn]
C[B13 and 15, capturing W10, is the proper counter measure.
];W[qq];B[qn];W[rn];B[rm];W[ro]
C[With 18 and 20 White gets the corner territory, but Black get
outside influence.
];B[fq]
(;W[fp]
C[W22 is the correct direction for responding to Black's approach.
See the variation.

(;B[cq];W[eq];B[cp];W[dm]
C[W26 is a good, appropriate move; White does not want to protect
at G3 as that would be too slow.
];B[dn];W[en];B[em]
C[Black's push and cut with 27 and 29 is the necessary course.
];W[cm];B[bm]
;W[el]
C[After B31, White's atari at 32 is a mistake that also causes
White to lose the initiative later in the game.
];B[fm];W[fn];B[dl];W[cl];B[dk];W[ck];B[cj]
C[After B39, White must make small life on the side. The continuation
to W58 is the only course.
];W[dj];B[ek]
;W[bj];B[ci];W[bl];B[al];W[bk];B[ej];W[bn];B[bo];W[am];B[bi]
;W[ak];B[ao];W[an];B[er];W[fr];B[dr];W[gq];B[jd]
C[B59: After Black gets this large point, he is clearly ahead in
the game.
];W[qf];B[pf]
C[B61 through 65 emphasize the corner territory.
]
;W[pg];B[qe];W[of];B[pe];W[mg]
C[W66: Since Black's right side position is rather thick, White
responds lightly at 66.
];B[fd];W[df];B[md];W[hc];B[ge]
C[B71 is a good attacking move in response to White's invasion
at 70, blocking White's connection to the corner.
]
;W[jc];B[kc];W[kb];B[kd];W[id];B[ie]
C[B77 to 81 is the natural continuation.
];W[lb];B[gc];W[gb];B[ib]
;W[hb];B[ic];W[hd];B[jb];W[he]
C[After W86, Black's three stones to the left are useless. White
has managed to make some gains here.
];B[ce];W[de];B[cf];W[cd];B[hf]
;W[if];B[je];W[ec];B[hg];W[rg]
C[W96: Black lost sente with 95, so White got to play first in
the upper right.  Now the position on the board is much closer.
Black should cut at R13 instead with 95; then he would be way
ahead in territory. However, W96 is also problematic, since after
B97 and 99, the entire white group becomes heavy. W96 should
be a solid connection at R13; then Black would not have any good
points at which to attack White.
];B[qh];W[qg];B[re];W[oi];B[mi]
C[B101 is severe.  Even though White is able to escape, the game
is basically lost.

However, Black makes several obvious mistakes in the endgame
and White is able to catch up. For example, B173 is gote, and
B185 and 187 would be more beneficial if reserved for later.
It was fortunate for me that I still had a one point advantage
at the end.

Black wins by 1 point.

C[After playing this joseki through W28, it is clear that the exchange
of 23 for 24 is bad for Black.
]))
(;W[dn];B[dm];W[en];B[cq];W[co];B[dq]
C[If White plays this way, Black plays 23 and then jumps into the
corner. This common joseki is not appropriate in this situation,
since the effectiveness of White's three stones in the bottom
center is tremendously reduced. We should strive to avoid any
move that damages or rerduces the effectiveness of the stones
we already have on the board.  For the same reason Black does
not play 23 in the game beside 22; see next variation.

(;B[qq];W[pm];B[ok];W[ro];B[rq];W[mo]
C[If Black plays this way, W14 is a good point to quickly erase
Black's formation. If B15, White plays 16, threatening to play
at 17 and make eye shape. Black must play 17, so then White connects
at 18. Comparing this variation to the old style of W13 and B14,
White's result is more efficient here.

(;W[mo];B[pn]
C[The old sequence.  Black's Chinese opening reaches its full potential
as the territory in the lower right is quite large.
]))
(;B[mq];W[op];B[nq];W[pp];B[qq];W[qp];B[lq];W[qm]
C[Playing this way, Black emphasizes territory. White's atari at
12 is aggressive; Black's intention of forming a large framework
utilizing his Chinese opening has been disrupted. Black's extension
to 17 here also disrupts White's intention of forming territory.
Both sides have succeeded in interfering with the other's intentions.
This becomes a different game.
