Event Black C. Jager, 5k, NL White P. Ryan, 9k, GB Result W+19 Source BGJ 63, November 1984, Page 13 Com Copyright British Go Association 1984, 1998 EndCom B 1 c4 W 2 r16 B 3 c17 W 4 q4 B 5 p17 W 6 n16 B 7 p15 W 8 q14 B 9 p14 Com 9, 11: It is wrong to give the opponent secure territory on the fourth line at the start of the game. EndCom W 10 q13 B 11 p13 W 12 q12 B 13 k16 W 14 l16 Mark A@n14 Com Trying to live locally is bad - simply jumping out to 28 (A) is quite sufficient to punish Black's poor play. EndCom VAR W 1 n14 ENDVAR B 15 k15 W 16 l15 Mark A@m14 Com Better at 25 (A). EndCom VAR W 1 m14 ENDVAR B 17 k13 W 18 o17 Com 18, 20: These moves make Black much stronger without helping White. EndCom B 19 p16 W 20 q17 B 21 p18 W 22 m13 B 23 p12 W 24 m11 Mark A@m14 \T@l13 \T@l12 \T@m12 Com It is usually incorrect to follow a knight's move with a one space jump because of the cut at 25 (A). White should play 36, 29 or 27 (\ts). EndCom B 25 m14 Com Black 25 - 31: These moves take full advantage of White's error. EndCom W 26 l14 B 27 l13 W 28 n14 B 29 m12 W 30 n13 B 31 n12 Mark #25-31 Com Black 25 - 31: These moves take full advantage of White's error. EndCom W 32 k14 B 33 j14 W 34 j13 B 35 j15 W 36 l12 B 37 k12 W 38 o12 Mark A@l11 B@n11 Com White cannot afford to connect at 39 (A), since the ladder does not work. Black would answer at 40 (B) and be able to handle the fight. EndCom VAR W 1 l11 B 2 n11 ENDVAR B 39 l11 Prisoner l12 W 40 n11 B 41 l12 W 42 o13 B 43 o11 W 44 p11 B 45 o10 W 46 k17 Mark A@m17 Com He could live with 47 (A) instead. EndCom VAR W 1 m17 ENDVAR B 47 m17 W 48 o18 Mark A@l17 Com Must connect at 58 (A) immediately. EndCom VAR W 1 l17 ENDVAR B 49 o9 Mark A@l17 B@r15 C@q11 Com Bad - Black should cut at 58 (A) - threatening 55 which reduces White's group to two liberties. Then she should cut at 51 (B), keeping the option of cutting at 50 (C) in reserve. After white 50 it is possible to play 54. EndCom VAR B 1 l17 ENDVAR W 50 q11 B 51 r15 W 52 q15 B 53 q16 W 54 r17 B 55 n15 Mark A@l17 Com Should still cut at 58 (A). EndCom VAR B 1 l17 ENDVAR W 56 m15 Prisoner m14 B 57 o15 W 58 l17 B 59 n18 W 60 n17 Com 60, 62: Makes sure of the capture. The white corner is enormous, but the game is not over yet since Black has a lot of thickness in the centre. EndCom B 61 j17 W 62 m18 B 63 c13 W 64 e3 Mark A@e4 B@e5 Com Better at 65 (A) - Black 65 and 67 (B) are good and threaten to take a huge side. EndCom VAR W 1 e4 ENDVAR B 65 e4 W 66 f4 B 67 e5 W 68 d3 B 69 c3 W 70 j3 B 71 c7 W 72 c12 Mark A@d12 Com Too deep - a shoulder hit at 83 (A) is preferable. EndCom VAR W 1 d12 ENDVAR B 73 d13 W 74 c8 B 75 c10 W 76 d10 B 77 c11 W 78 d6 Mark A@d7 Com Appalling - must hane at 80 (A). EndCom VAR W 1 d7 ENDVAR B 79 c5 Mark A@d7 Com Lets White off the hook - 80 (A) would kill most of White's invading stones. EndCom VAR B 1 d7 ENDVAR W 80 d7 B 81 c6 W 82 c9 B 83 d12 Mark A@d11 Com Better at 84 (A). EndCom VAR B 1 d11 ENDVAR W 84 d11 B 85 f5 W 86 g4 B 87 b12 Prisoner c12 W 88 e8 B 89 g5 W 90 g8 B 91 h5 W 92 k5 Com Ambitious. EndCom B 93 j6 Mark A@j8 Com Too passive. Black should shut White in more tightly with 94, which also restricts his eye space a bit. EndCom VAR B 1 j8 ENDVAR W 94 j8 B 95 j4 W 96 j11 Mark A@m10 Com 96, 98: Horrible aji keshi moves. The main thing White had to look forward to in this area was pulling out his cutting stones at 99 (A). EndCom B 97 j12 W 98 m9 B 99 m10 W 100 h4 B 101 j5 W 102 k7 B 103 h8 W 104 h9 B 105 h7 W 106 f9 Mark A@g9 B@j9 Com Should connect at 116 (A) or 118 (B). EndCom VAR W 1 g9 ENDVAR B 107 h3 W 108 g3 Mark A@h2 Com Bad shape and dangerous - should be 109. EndCom VAR W 1 h2 ENDVAR B 109 h2 W 110 g2 B 111 k6 Mark A@j9 Com Should cut at 118 (A) - White will have to make eyes in the centre. EndCom VAR B 1 j9 ENDVAR W 112 k9 B 113 k3 Mark A@j2 Com Aji keshi - she could play 114 (this is why 108 was bad). EndCom VAR B 1 j2 ENDVAR W 114 j2 B 115 g10 W 116 g9 B 117 j10 W 118 j9 B 119 h10 W 120 l10 B 121 k10 W 122 n10 Prisoner m10 B 123 n9 W 124 m8 Com 124, 126: Rather cowardly, but now he is definitely alive. EndCom B 125 m10 Prisoner m11 n11 n10 m11 n11 n10 W 126 m7 B 127 o3 W 128 o4 B 129 n4 W 130 o5 B 131 p3 W 132 q3 B 133 q6 W 134 q5 B 135 p6 W 136 n5 B 137 m4 W 138 o7 B 139 p8 W 140 h17 Mark A@j18 Com White is slightly ahead if he just hanes at 141, so this invasion is wrong. EndCom VAR W 1 j18 ENDVAR B 141 j18 W 142 d17 B 143 c16 W 144 h16 B 145 j16 W 146 c18 B 147 f17 Mark A@e18 Com Better to peep one point above 150 (at A). EndCom VAR B 1 e18 ENDVAR W 148 f18 Com A reasonable try, though he should die here. EndCom B 149 d16 Mark A@e18 Com At the last moment Black loses her nerve and lets white live. The hane above 150 (at A) actually kills very easily. EndCom VAR B 1 e18 ENDVAR W 150 e17 B 151 f16 W 152 b18 B 153 d19 W 154 e19 B 155 g18 W 156 b17 Com White 156, Black 159: White contrives to live in sente. EndCom B 157 e16 W 158 d18 B 159 b16 W 160 r9 Com Taking this point gives White a clear-cut victory. The final margin was 19 points. EndCom
