Event Black Jim Barty, 4d White Terry Stacey, 5d Place Challengers league Komi Guess=5 Result B+4 Analysis J Barty Source BGJ 63, November 1984, Page 23 Com Copyright British Go Association 1984, 1998 EndCom B 1 q16 W 2 d4 B 3 q3 W 4 c16 B 5 e16 W 6 e17 B 7 f17 W 8 d17 B 9 f16 W 10 c14 B 11 k16 W 12 q6 Com Presumably White is playing so far back in order to discourage a Black pincer, but in this position Black can go ahead anyway. EndCom B 13 r8 W 14 q4 B 15 p3 Mark A@r3 Com More usual is to pull back to the 3-3 point. This leads to the joseki shown in the variation EndCom VAR B 4 r3 Mark 1@q6 2@r8 3@q4 W 5 o4 B 6 p3 W 7 o7 B 8 n3 Mark A@q9 B@r17 C@r11 Com ..., but such a high position would enable White to press at 'A' before invading at 'B', or simply to pincer at 'C'. EndCom ENDVAR W 16 r3 B 17 r2 W 18 r4 Com The joseki books give the more elegant hanging connection at the right of 18. EndCom B 19 n4 Mark A@s2 Com More severe would be to play immediately at 20 (A), but White has more threats against the black group, so it is easier for White to advance into the centre. I preferred to let White settle on the edge. EndCom W 20 s2 B 21 j3 W 22 r14 B 23 o16 W 24 s16 B 25 r12 Mark A@r17 #13 Com It is also possible to play at 26 (A), but I preferred to strengthen black 13 and take the centre-facing position. EndCom W 26 r17 B 27 r15 W 28 s15 B 29 q14 W 30 s14 B 31 q13 W 32 o18 B 33 n18 Mark A@p18 B@f13 C@n17 Com This is a horrible mistake. I must play at 34 (A). The sacrifice of this stone would enable me to block off the side in sente, and then jump to 38 (B). Black 35 (C) is gote, but even then White has let me off the hook - consider white 34' at 35... EndCom W 34 p18 B 35 n17 W 36 g3 B 37 j5 W 38 f13 Com White gets there first. EndCom B 39 c9 W 40 c5 B 41 c12 Com Gives White a shape problem. EndCom W 42 d13 Com Patches the white shape while maintaining pressure on the two black stones, but there are still weaknesses in White's position. Since white 40 is so far away, I decided to see what I could generate from the aji straight away. EndCom B 43 b15 W 44 b14 B 45 e14 W 46 e13 B 47 c15 W 48 d15 B 49 d16 W 50 c17 B 51 d14 W 52 a15 B 53 e15 Prisoner d15 W 54 b16 B 55 c13 Com Cuts off the white stones, but White can be content because he will be able to settle his stones by jumping into the centre and further nullify Black's thickness. EndCom W 56 d11 Com White 56 - Black 59: White is a little unlucky that Black can push up at 59 and hane at 61, since the White push (at 96) and cut (at eg 140) doesn't work in this position. It would therefore be better for White to jump to the point above 62 or some such vaguer move. EndCom B 57 c11 W 58 d10 B 59 d9 Mark #56-59 A@e8 B@c10 C@b11 Com White 56 - Black 59: White is a little unlucky that Black can push up at 59 and hane at 61 (A), since the White push (at 96 (B)) and cut (at eg 140 (C)) doesn't work in this position. It would therefore be better for White to jump to the point above 62 or some such vaguer move. EndCom W 60 e9 B 61 e8 W 62 f9 B 63 c7 W 64 j13 B 65 f8 W 66 g9 B 67 l13 W 68 j15 B 69 j16 W 70 k11 B 71 e2 Mark A@e3 Com Black has acquired enough thickness to invade. The invasion at 87 (A) is more natural here, but for some reason it never occurred to me. EndCom W 72 f3 Com White decided to kill the Black invasion; he can reduce Black to one eye, but he is left with a cutting point. Neither player read out the ensuing semeai correctly before embarking on this sequence. Amateurs! EndCom B 73 c3 W 74 d3 B 75 d2 W 76 b3 B 77 b2 W 78 b4 B 79 f2 W 80 g2 B 81 a2 W 82 f1 B 83 e1 Com White decides that if he reduces Black to one eye, Black can push and cut, and have enough liberties to kill half the white group. So he seeks compensation by messing up Black's position next door. EndCom W 84 j2 B 85 c2 W 86 k3 B 87 e3 Com Black's compensation is the push and cut. EndCom W 88 e4 B 89 f4 W 90 g5 B 91 f5 W 92 f6 B 93 e5 W 94 d8 Mark #76 #78 Com The position is tricky for White. I think it would have been better to push on and sacrifice three stones to connect out 76 and 78, as this weakens the black group on the left hand side. EndCom B 95 e6 Com The white centre group is settled, so I am content to sacrifice the cutting stones and take a large corner. EndCom W 96 c10 B 97 b9 W 98 b10 B 99 h3 Mark #19 #15 #17 #3 Com Black now has a slight lead, but it is essential that the group (19, 15, 3, 17) is settled before it becomes an embarassment. The 99, 101 sequence forces the 102, 103 exchange which helps Black. (BGJ had 19,15,2,17.) EndCom W 100 h2 B 101 g4 W 102 m3 B 103 n3 W 104 k5 B 105 l4 W 106 k4 B 107 l2 W 108 j6 B 109 h5 W 110 l3 B 111 m2 W 112 k2 B 113 k6 W 114 l6 B 115 k7 W 116 n6 B 117 n5 W 118 l5 B 119 o6 W 120 l7 B 121 j7 Com This is essential. The game is now difficult for White to win. EndCom W 122 q8 B 123 q9 W 124 p8 B 125 r7 W 126 r6 B 127 r1 Com Black lives, but this may not be the best move, as White promptly demonstrates. EndCom W 128 o2 B 129 n2 W 130 s1 B 131 p2 Mark #17 #127 Com Allows White to capture 17 and 127, but in gote. EndCom W 132 n7 B 133 p9 W 134 o9 B 135 o10 W 136 n9 B 137 a10 W 138 a11 B 139 a9 W 140 b11 B 141 n12 Com A compromise but probably best, considering his bad aji. EndCom W 142 o11 B 143 p11 W 144 n10 B 145 p10 W 146 n11 B 147 o12 W 148 g8 B 149 f7 Mark A@g7 Com I was hallucinating non-existant dangers, should be at 224 (A). My play starts to go downhill as Terry puts the pressure on. In the yose that follows points are gained and lost by both sides, but overall White gains ground rapidly. EndCom W 150 f18 B 151 g18 W 152 e18 B 153 j9 W 154 h18 B 155 g17 W 156 g19 B 157 j18 W 158 h17 B 159 h16 W 160 g15 B 161 j17 W 162 h19 B 163 j19 W 164 f19 B 165 h15 W 166 g14 B 167 g16 W 168 s10 Mark A@r9 B@s8 Com Skilful play. This aims at the cut at 'A', perhaps preceded by the clamp at 'B'. EndCom B 169 s11 Com When Black takes this liberty away all the immediate sequences lose for White... EndCom W 170 p1 B 171 o3 W 172 q2 B 173 o1 Prisoner o2 W 174 s12 Mark A@r10 B@s8 Com ... The counter tesuji. If White can play kikashi at 182 (A) before the clamp of 'B' then a rather large ko ensues. EndCom B 175 r11 W 176 t11 B 177 s9 W 178 r13 B 179 s6 W 180 s5 B 181 s7 W 182 r10 B 183 q10 W 184 q12 B 185 q11 W 186 q1 Prisoner r2 r1 B 187 h10 W 188 k13 B 189 l14 W 190 m12 B 191 m13 W 192 k15 B 193 l15 W 194 h4 Mark #149 Com 194, 196: Worth 4 points in gote, but possible because of Black's mistake at 149. EndCom B 195 h6 Prisoner j6 W 196 j4 Prisoner h3 j3 B 197 g11 W 198 f11 B 199 l9 Com A bamboo joint is better, White immediately tempts Black into an indiscretion. EndCom W 200 g12 B 201 h12 W 202 j11 B 203 h11 W 204 k8 B 205 j8 W 206 j10 B 207 h9 W 208 k9 Com Black's lead is still there, but it is dangerously small. EndCom B 209 l12 W 210 m11 B 211 l11 W 212 l10 B 213 h13 W 214 h14 B 215 g13 W 216 f14 B 217 f12 Prisoner g12 W 218 e11 B 219 q17 W 220 q18 B 221 o19 W 222 r16 B 223 q15 W 224 g7 B 225 g6 Prisoner f6 g5 W 226 d15 Prisoner b15 c15 B 227 k14 W 228 j14 B 229 o7 W 230 o8 B 231 c15 Prisoner d15 Com This move was not shown in the BGJ diagram. This location is a guess based on the assumption that the move was omitted from the diagram because a stone was already there in "Figure 4". EndCom W 232 p5 B 233 o5 W 234 p19 B 235 n19 W 236 p17 B 237 p16 W 238 m4 Prisoner l4 B 239 m5 W 240 p4 B 241 m6 W 242 m7 B 243 t5 W 244 t4 B 245 t6 W 246 g1 B 247 k1 W 248 j1 B 249 l1 W 250 t9 B 251 t8 W 252 t10 B 253 e12 W 254 d12 B 255 g12 Com This move was not shown in the BGJ diagram. This location is a guess based on the assumption that the move was omitted from the diagram because a stone was already there in "Figure 4". EndCom W 256 g10 B 257 h7 Com Black 257 was the last recorded move. Fortunately for me the last 50 points were straightforward. Black wins by 4 points. EndCom
