EndCom B 23 s8 Com Black 23 is strange shape, though it does have the merit of undermining white's eyeshape. EndCom W 24 r13 Mark A@o17 B@l16 Com White 24 feels like a bit of an overplay. The danger is that he may get two weak groups in the same part of the board. More usual would be 50 (A) or 64 (B). EndCom B 25 n17 W 26 s16 B 27 r17 W 28 r11 B 29 s10 W 30 s7 B 31 s14 Mark A@o9 Com Black 31: A standard tesuji, undermining the white group, but it might have been better to come out at 38 (A) first. With 38 white gets some sort of counter attack started. EndCom W 32 r14 B 33 s15 W 34 r15 B 35 r16 W 36 s13 B 37 s17 W 38 o9 B 39 p10 W 40 o10 B 41 p11 W 42 p9 B 43 q8 W 44 p7 B 45 s11 W 46 r12 B 47 q10 W 48 o15 B 49 o11 W 50 o17 B 51 o16 W 52 n11 B 53 n12 W 54 o13 B 55 m11 W 56 n10 B 57 o12 W 58 m14 B 59 p15 W 60 o14 B 61 n15 W 62 n14 Mark A@m13 Com White 62: Bad shape, making an empty triangle; the bamboo joint (playing one point below 58 (at A)) would be better. EndCom B 63 l12 W 64 l16 Mark B@m15 Com 62 loses any shred of meaning when white plays 64, which should be atari to the left of 61 (at B). EndCom B 65 j16 W 66 k14 B 67 h14 W 68 j13 B 69 j11 W 70 h13 B 71 e17 Com Black 71: Remarkable, but bad. He is trying to get some forcing moves in (75, 77, 79) so as to be able to continue the attack, but the main effect of these plays is to secure White's corner absolutely. Lateron when black gets cut off in this area he dies easily due to these crude plays. EndCom W 72 e16 B 73 e18 W 74 d16 B 75 g17 W 76 f18 B 77 g18 W 78 d18 B 79 f16 W 80 e19 Prisoner e18 e17 B 81 f14 W 82 g11 B 83 p8 Com Black 83, 85: Takes advanage of White's earlier overplay - now with three weak groups on the right White has to sacrifice one of them. EndCom W 84 o8 B 85 o7 W 86 o6 B 87 n7 W 88 n6 B 89 m7 W 90 n4 B 91 n3 W 92 m3 B 93 m4 W 94 n5 B 95 o3 W 96 l4 B 97 p6 W 98 p5 B 99 m5 W 100 m6 B 101 l5 W 102 l6 B 103 k5 W 104 l7 B 105 m8 W 106 l8 B 107 m9 W 108 k10 B 109 r7 W 110 q6 Prisoner p6 B 111 m10 W 112 h3 B 113 l13 W 114 m15 Com White 114, 116: Very good - White refuses to answer Black's intended forcing play and begins an atack on the left. EndCom B 115 n16 W 116 k16 B 117 l14 Com Black 117, 119: Black must have misread something here - these moves do not work. EndCom W 118 j17 B 119 l15 W 120 m16 B 121 k15 W 122 h16 B 123 g16 Mark A@j15 Com Black 123: Now that he has got this far it might be better to play 124 (A), letting white capture the side with 123 (Black has got plenty of territory) in exchange for power in the centre. EndCom W 124 j15 Prisoner j16 B 125 j14 W 126 g14 B 127 k13 Prisoner k14 W 128 h15 B 129 k14 Com BGJ omitted 129 from its diagram. I have guessed that it is played here. === sgb EndCom W 130 g15 B 131 f15 W 132 f13 B 133 e5 W 134 d6 B 135 f3 W 136 f2 Com White 136-142: Too docile. He should either play 140' at 142, or 142' at 143. Black must not be allowed to cut off the White stone (112) on the side. EndCom B 137 e2 W 138 d2 B 139 e4 W 140 d3 B 141 g2 W 142 e1 Prisoner e2 B 143 g3 W 144 h4 B 145 g5 W 146 h5 B 147 j2 W 148 h2 B 149 h1 W 150 h6 B 151 b8 W 152 c12 Com White 152: Very sharp, and White's last chance - but almost too late. It would have been better to play 144' at this point. EndCom B 153 d12 W 154 c11 B 155 d11 W 156 b10 B 157 b9 W 158 d10 B 159 c9 W 160 b14 B 161 b13 W 162 c13 B 163 f12 W 164 b12 B 165 f11 W 166 e13 B 167 d13 W 168 e10 B 169 g12 W 170 g13 B 171 e8 W 172 f9 B 173 j10 W 174 k11 B 175 j9 W 176 j12 B 177 f8 W 178 g9 B 179 g8 W 180 h9 B 181 h8 W 182 h11 B 183 j7 W 184 h12 B 185 e9 W 186 f10 Com Up to 186 White successfully cuts off and kills the entire upper black group. However his own lower right group, which is bigger, gets cut off itself. The moves from 188 to 194 merely waste ko threats.

Dia 1 (Variation on move 222) shows the problem, and also why Black 223 effectively sealed the game.
