ENDCOM W 20 f5 B 21 f3 W 22 e4 PRISONER e5 B 23 j4 COM Black 23: Leaves many weaknesses, it would be better to play one point to the left.

ENDCOM W 36 f9 B 37 f8 W 38 h9 COM White 38: Overplay - he is trying to shut the black group in to make me add an extra stone in the corner but this is unreasonable - 38' should be one point to the right. ENDCOM B 39 g9 W 40 g10 B 41 f10 W 42 h10 B 43 d9 MARK A@e10 COM Black 43: Better at 50(A) - black is straining too hard to get sente. ENDCOM W 44 c8 MARK A@f11 COM White 44: Better at 51(A) - white is straining too hard to make Black add a stone in the corner. ENDCOM B 45 c10 W 46 c11 B 47 b10 W 48 b11 B 49 q5 MARK A@f11 COM Black 49, White 50: Both better at 51(A). ENDCOM W 50 e10 MARK A@f11 COM Black 49, White 50: Both better at 51(A). ENDCOM B 51 f11 W 52 e12 MARK A@e9 #30 COM White 52: 53(A) is impossible since Black would cut above 30 and kill many stones. ENDCOM B 53 e9 PRISONER f9 W 54 g13 B 55 h8 W 56 j8 B 57 j9 W 58 b1 B 59 a2 W 60 l8 B 61 k9 W 62 l6 MARK A@m3 COM White 62: He has to play here - the white group dies first if he starts a semeai. The result is not bad for White, though - even after 65(A) black’s lower side is weak. ENDCOM B 63 j11 W 64 m7 B 65 m3 W 66 r4 B 67 f12 W 68 f13 B 69 r5 W 70 q4 B 71 p5 W 72 o4 B 73 r9 W 74 l17 B 75 k16 COM Black 75-99: Both sides strain as hard as possible - the issue is not so much whether Black lives in the corner as what happens on the outside while he is doing so. If 98' is at 99, Black plays below 91 saving his two stones 93 and 95 and getting a big centre. ENDCOM W 76 k17 B 77 j16 W 78 j17 B 79 c17 W 80 d17 B 81 c16 W 82 c15 B 83 b15 W 84 b14 B 85 d18 W 86 e18 B 87 e17 W 88 e16 B 89 c18 W 90 d14 B 91 f17 W 92 f18 B 93 e13 W 94 e11 B 95 d13 W 96 c13 B 97 h12 W 98 g17 B 99 b16 MARK #75-99 COM Black 75-99: Both sides strain as hard as possible - the issue is not so much whether Black lives in the corner as what happens on the outside while he is doing so. If 98' is at 99, Black plays below 91 saving his two stones 93 and 95 and getting a big centre. ENDCOM W 100 h3 MARK #23 COM White 100: Both players have been waiting for this one - Black’s overplay at 23 comes home to roost. ENDCOM B 101 j3 W 102 j2 B 103 k2 W 104 h2 B 105 h4 MARK A@g5 B@f2 C@g4 COM Black 105: Misses the best play - this should have been at 133(A), White cannot reply one point above (Black would descend at 106(B) and kill)- so he would have to cut at 145(C), allowing Black to cut through the centre, securing his stones absolutely. This would separate six white stones in the centre, and with weakish stones in the centre White would be unable to invade the right side deeply. Thus Black would get compensation for sacrificing his two stones.

ENDCOM B 115 n3 W 116 o5 MARK #114 A@r11 COM White 114, 116: These two stones are White’s profit from his attack, now 118(A) becomes a severe invasion and Black has little chance of getting enough territory.
