];B[qd]
C[Black 1 is the commonest opening; White can respond in any corner.
];W[dc];B[oc]
C[Black 3 is a solid move which gives White, and not Black, the
choice of playing in opposite corners or down the sides.  
];W[pp]
C[White 4 is an influential move (4th line) balancing 1 & 3.  
]LB[oc:3][qd:1]
;B[cp];W[eq];B[hp];W[fp]
;B[dn];W[fn]
C[White 10 is another influential move, threatening Black's stone
7 (e.g. by playing A) and Black's 5 & 9 group.  
]LB[jq:A][dn:9][cp:5][hp:7]
;B[kp];W[cr]
C[White 12 secures room for eyes and takes away similar possibilities
from Black.  
];B[bq]
C[Black 13 has a similar, but smaller, effect to that of White
12. It could be replaced by an extension to B but 13 by White
will then threaten strong invasion.  
]LB[ck:B][cr:12]
;W[cj];B[cl]
C[Black 15 is necessary to prevent white from jumping any nearer
the black group after the attack with 14.  
]LB[cj:14]
;W[ej]
C[White 16 is to discourage black from invading at C and threatens
to wall black in at 17(A), leaving Black with a small live group
and no influence at all in this area.  
]LB[el:A][ch:C]
;B[el];W[fl]
C[White 18 still threatens to enclose black.  
]
;B[fk]
(;W[gl]
C[White 20 is good form, better than any other move in this area.
Also White cannot cut black at 21(A)  because of D, E and then
F, attacking the white group. See variation.  
]LB[hm:F][gm:E][fm:D][ek:A]
;B[ek]
C[Black 21 concludes the sequence stared with 18 by which White
has strengthened his lower group with sente. White now has time
to support his last corner with 22 (A) giving Black a choice
between extension along the top or down the right hand side.
]LB[de:A][ek:21][gl:20][fk:19][fl:18]
;W[de];B[jc]
C[Black 23 stops White forming an ideal formation of 5 stones in
the top left corner.  
];W[qj]
C[White 24 then automatically grabs the other side - 24 is the
best point - and now threatens to dominate the lower centre and
right part of the board. Should black invade the corner white
would wall him in and feel very pleased with his great outward
influence from his right and left groups working together.  
];B[nq]
C[Black 25: So Black plays the usual attack and pushes further
into the corner to strengthen his group against attack.  
];W[pn];B[pr];W[qq]
C[White 28 is large and best.  
]
;B[qh]
C[Black 29 is a good extension, threatening invasion at G.  
]LB[ql:G]
;W[oj]
C[White 30: prevents the invasion at G, forming an ideally strong
5-stone formation.  
]LB[ql:G]
;B[oh]
C[Black 31 leaves White to do something about Black's great sphere
of influence and good prospects in the top right corner.  
];W[je]
C[White 32 is not the best way for to do something about Black's
great sphere of influence and good prospects in the top right
corner; H is better, and if black replies at 32 then white invades
at, for example, 34 (A).  
]LB[le:A][hc:H]
;B[jd]
C[Black 33 is a good defensive move, though heavy, because it anticipates
39 (A).  
]LB[fc:A]
;W[le]
C[White 34: Light, as it should be. Heavy play is far worse when
attacking than when defending.  
];B[ie];W[jf];B[if];W[jg]
C[White 38 is best. If White is tempted to play 42 (A), black will
just cut at 38.  
]LB[ig:A]

;B[fc]
C[Black 39: The profitable move, threatening invasion of the corner,
for example at J, which White should have anticipated at move
32.  
]LB[je:32][cd:J]
;W[fe];B[gd];W[ig];B[gf];W[lc];B[hg];W[fi]
C[White 46 protects against a black invasion of White's territory,
which black's creep to the left is threatening despite the strengthening
exchange of 40 for 41. Now Black takes as much profit as he can
in this bit of the board and then turns elsewhere ... (see move
57) 
]LB[gd:41][fe:40]
;B[eg];W[fg]
;B[di];W[dj];B[ff];W[dg];B[df];W[cf];B[ef];W[ch];B[ri]
C[Black 57: (from 46) ... to make this valuable move (about 8 points).
];W[rj]
C[White 58: A necessary defensive move.  
]
;B[no]
C[Black 59: An excellent move, increasing Black's territory while
preventing White from doing likewise with the same move.  
];W[hq]
C[White 60: After 59, this is the furthest that white can safely
come into the black group.  
];B[iq];W[gq];B[ir];W[oe]
C[White 64 is the usual attack on this corner formation and ...
];B[pf]
C[Black 65: ...  the usual defensive reply on that side.  
];W[hi]
C[White 66, 68: help to make White's large group alive.  
];B[hh];W[ii]
C[White 66, 68: help to make White's large group alive.  
]
;B[nl]
C[Black 69 threatens K or L spoiling White's territory. But it
is a risky move because it can be cut, as happens with the game,
thereby jeopardising Black's chances in a position that is favourable
to him, thanks to White's earlier mistake (with 32).

C[Black 75' could be changed to N as in variation.  
];W[ll];B[nj];W[ni];B[ol];W[pm]
C[White 80 is the best way to save the two stones and prevent black
from invading. Black now tries to connect to the top right corner
but fails and has to try and make eyes in the centre or connect
to another black group.

;W[pi];B[mg];W[og];B[ph];W[ng];B[mh];W[mf];B[kk];W[kl];B[ok]
C[Black 93: Black supposed that this gave him the chance of playing
at L later, but this is answered by M.

;W[pj];B[nd];W[ne];B[jl];W[jm];B[jk];W[kn]
C[White 100: After this, White threatens to cut with 108 thanks
to 66 & 68.

C[Black 109 is a mistake as will be seen later.  
];W[nf];B[ki]
C[Black 111 - 127: All Black's moves from 111 to 127 are strong
sente moves, profitable enough to put Black back in the game
with a chance.

C[White 116 is necessary by white because of the alternative in
the variation where black is alive in the corner.

C[Black 137: If black had not earlier made the exchange of 109
for 110, he could have saved himself after white 136 by playing
137' at 138 (A).

black's potential territory while slightly increasing white's,
Black is losing by about 15 points.
