C[White 6: This, with 2 and 4, makes the low Chinese fuseki, which
I occasionally meet with against my san-ren-sei (1, 3, and 5).
Black 7 is on such a good point for white that it seems to me
that black can take a small early lead, but the move brought
no comment from the pro.  
];B[jd];W[jp]
;B[cn]
(;W[fp]
C[White 10': Normally played at C; then black D, white 10, black
13.  The shape that black gets with 11 and 13 is better than
this.  
]LB[dn:D][co:C]
;B[bp];W[cq];B[ck]
(;W[cf]
C[White 14: Not too bad, but rather low and flat. Mrs Feng suggested
A. John was concerned about the possible invasion at B if he
played there, but the professional thought that he had enough
pressure against the black group below to withstand it.  
]LB[cg:B][de:A]
;B[lq]
C[Black 15: I found it hard to choose between this, 74(A), and
the points below and left of 98(B). Mrs Feng politely said that
they were all good points, and that 15 was as good as any.  
]LB[gc:B][mp:A]
;W[qf];B[qe];W[pf];B[nd];W[ph];B[qi];W[oj]
;B[ok]
C[Black 23: Better at 35(A), because after white 30(B) and black
31(C) white cannot capture it in a ladder, which ends on 7. Therefore
white 22 should be at 50(D).  
]LB[ni:D][jd:7][qj:C][pi:B][oi:A]
;W[nj];B[nh]
C[Black 25: A rather loose move, which is normally played at 30(B)
in this line. But it looks good, making the eye-stealing tesuji
with 5, and I use it to frighten my opponents when I fancy my
chances.

C[White 34: Too conservative; should be at 67(A).  
]LB[pn:A]
;B[oi];W[qc]
C[White 36 et seq.: With this move, John decides to give up four
stones including 16 to live in the corner. Mrs Feng thought that
this sacrifice was too large, and that it puts Black clearly
ahead.  
]LB[qf:16]
;B[re];W[oc];B[od];W[nc];B[pc];W[pb]
;B[mc];W[mb];B[lb]
C[Black 45': Should be at 47(A). After 47 I have gote anyway, but
if I omit 45 I have the option later of cutting above 36 and
taking the corner; white then lives along the upper edge. I can
still choose to play 47 in sente later on if I prefer. 45 is
a clear case of aji-keshi.  After 47, the point left of 98 (at
B) becomes a big point for me ...  
]LB[fc:B][qc:36][lc:A]
;W[nb];B[lc];W[mh]
C[White 48 - 52: ... but John has some aji-keshi of his own to
play.  The pro criticised these moves, especially 52, as being
too early, even if only kept for ko threats. A nasty cut is left
behind at E.

]LB[mi:E]

;B[nf];W[qq];B[pq];W[qp];B[qr]
C[Black 57: Choosing this line instead of 66(A) hopes to make use
of the aji around 67 and 69 (/[\]); there is a threat to capture
three stones and thus weaken the group as a whole. This move
won professional approval.  
]LB[qo:A]
;W[rr];B[pr]
(;W[ro]
C[White 60 and 62: But these ones didn't. 66(A) instead of 60 makes
the right shape. 62 makes only one eye; he should start escaping
to the centre immediately.

the right shape. 62 makes only one eye; he should start escaping
to the centre immediately.  
];B[rn]
C[Black 63: I missed a chance to capture the corner here by playing
a point above 58. If black extends from 58, Black plays 66(A)
and the entire white group dies.  
]LB[qo:A][rr:58]
;W[po]
(;B[qn]
C[Black 65': I should play this at 67(A), not fearing the ko. 
]LB[pn:A]
;W[qo];B[pn];W[oo];B[on];W[nm]

C[Black 71: Misses a chance to kill white off completely by playing
at F.  
]LB[no:F]
;W[np]
(;B[nq]
C[Black 73: I debated long whether to play here or a point below.
What I didn't think of was the correct shape at 75(A); then I
am a jump ahead of white in the race to the centre. 73 becomes
a redundant move.  
]LB[mq:A]
;W[mp];B[mq];W[lp];B[kp];W[ko];B[kq];W[ln];B[jq]
C[Black 81: Rather a slow move. When I pointed out that I was playing
solidly because I was ahead in the game, Mrs Feng appeared satisfied.
The move is certainly huge territorially.  
]
;W[ip];B[iq];W[bq]
C[White 84: This too is huge, and greatly weakens 11, 9, and 13.
Nonetheless, it was criticized as being yose and too early. 
]LB[ck:13][bp:11][cn:9]
;B[hp]
C[Black 85: This move, the proverbial hane at the head of two stones,
keeps the lower right white group separated from the newly strengthened
lower left group, and looks forward to making use of the aji
around 71 and at E. I hope that my attack will be more severe
than the expected attack on my left hand group ...  
]LB[mi:E][nn:71]
;W[bm]
C[White 86 - 92: ... which promptly materializes. Having played
tenuki from 84, I can no longer expect territory or even eyes
on the left.  
];B[cm];W[bl];B[cl];W[bn];B[di]
;W[ch];B[in]
C[Black 93: Right idea, wrong point; should be G, to give more
help to the the left hand group. I should not be trying to threaten
8 and 82 because my bottom group is already very strong.  
]LB[ip:82][jp:8][hn:G]
;W[fm];B[fk];W[ho];B[hq]
C[Black 97: Another very solid move played in the same spirit as
81.  
]LB[jq:81]

(;W[gc]
C[White 98: Enormous yose, but not urgent. John should continue
the attack on my left side group, hoping to patch up his bad
aji on the other side in the course of so doing. Mrs Feng suggested
H.  
]LB[fi:H]
;B[cc]
C[Black 99: Yosu-miru; see Strategic Concepts of Go, Chapter 8.
After White 100(A) I can live in this corner with ko.  
]LB[dd:A]
;W[dd];B[mi]
C[Black 101 - 113: The time has at last come to use the aji on
the right. After 111 John decided to strengthen his upper group,
but 113 captures the lower right group completely -- the two
cuts below 'triangle' and 113(A) are miai.  But I have to be
careful to keep enough liberties on the group including /\\. As
the position stands, it is likely eventually to be necessary
to fill in all the White group's liberties.

;B[go]
C[Black 117: This move seems to be small, and leaving the left
side group to its fate. But now I no longer have to fill in the
said liberties to keep the centre group alive, so that it can
be used aggressively.  
];W[ie]
C[White 118: John could kill off my left side group cleanly with
127(H).  The trouble is that he has now lost too much territory
for this to give him a winning position; he needs to capture
it on a large scale, i.e.  taking a goodly chunk of territory
with it. White 118 attempts this, but ...  
]LB[fi:H]
;B[fn]
C[Black 119: This was another reason for 117. I cut off a small
White group, and because the centre group is now strong and aggressive
John has to defend eventually at 126(A). My group now has one
eye, and a series of threats either to make another or connect
out left this group safe.

C[The record ends at 159; John resigned a few moves later.  John
made a number of uncharacteristically passive moves in this game.
I too missed chances, but in the end it was the bad aji that
John left behind which did for him.
