EndCom W 14 d17 B 15 e17 W 16 f16 B 17 e18 W 18 b16 B 19 c14 Com Usually Black plays 21 to 25 first. In the game White has the option of living quickly with 20 at 22, so as to leave his cutting stones in the centre more room. The game result is good for Black.

White has spotted a way to rescue his weak group at the top. Black has no ko threats so he has to play 59.

Black would then be very embarassed, since he could not continue the ko without risking his whole centre group. EndCom W 116 e10 B 117 m7 W 118 h5 B 119 g5 W 120 h4 B 121 l4 W 122 l6 Com 122 - 128: This looks like just the sort of ignominious grovelling for life that loses games - Black's wall gets stronger and stronger. However ... (see 130) EndCom B 123 m6 W 124 l3 B 125 m3 W 126 k3 B 127 m4 W 128 l8 B 129 m8 W 130 l12 Com White finds a sharp counterattack, gains time to protect his upper group at 140, and makes the forcing moves 122 to 128 look like preparations for a large scale attack on the black group. EndCom B 131 l13 W 132 m12 B 133 n12 W 134 l11 B 135 n13 W 136 m10 B 137 n11 W 138 n10 B 139 o11 W 140 n18 B 141 l9 W 142 l10 B 143 k9 W 144 j9 B 145 p10 W 146 g6 B 147 e7 W 148 o8 B 149 p9 W 150 n8 B 151 p5 Mark #130-150 Com White must be separated and the black stones need eye space, but it is awfully painful to let White strengthen his corner with 152, 156 and 158. If White had not broken through the black wall with 130 - 150, but had simply made eyes, then Black could have attacked the lone white stone in the corner vigorously, and built himself a large territory on the side while doing so.

EndCom B 177 g3 W 178 h3 B 179 f2 W 180 k5 B 181 s9 W 182 r16 Mark A@q2 Com 182, 184: He seems to be afraid of some large scale attack on the group in this area, but 185 (A) is a very big move to allow. EndCom B 183 s16 W 184 q18 B 185 q2 W 186 r2 B 187 p3 Prisoner o3 W 188 q3 B 189 p1 Prisoner p2 W 190 r19 B 191 r15 Prisoner r16 W 192 n14 B 193 s2 W 194 s3 B 195 r1 W 196 r3 B 197 s5 W 198 r5 B 199 s8 W 200 r9 B 201 r10 W 202 t8 B 203 s10 W 204 p14 Mark A@s4 Com Both sides seem to misread this corner - White must play 205 (A) to avoid being killed. EndCom B 205 s4 W 206 s1 B 207 t1 Prisoner s1 W 208 t3 B 209 q1 W 210 t7 B 211 t5 Com Seki - but if he had played one point lower White would be unconditionally dead. (After that Black could fill all the outside liberties and then make an"eye in the belly" by playing one point above 211. If at any stage White tried to prevent this, White could reduce the stones inside to a one eyed lump.)

EndCom B 243 o17 W 244 o18 B 245 n16 W 246 r14 Com White 246 is very sharp - he lives inside Black's territory with 254.
