EndCom VAR W 1 a7 ENDVAR B 61 b5 W 62 e14 Mark #47 Com White 62: (M) Could try killing the group, but black could push up above 47, save the cutting stone, and create all sorts of trouble. 62 is enough. EndCom B 63 a7 W 64 e11 B 65 f13 W 66 f7 Mark #47 Com White 66: (M) Kills 47 with good aji. EndCom B 67 g9 W 68 d12 B 69 d10 W 70 g11 Mark A@c15 Com White 70: (S) Overplay because of 75 (A).

I had failed to spot that 80' at 81 would get black 80 gaining a liberty and killing outright. EndCom VAR W 1 c17 ENDVAR B 79 b14 W 80 b16 Mark A@c17 Com White 78: (M) Lunatic. It must be at 81. I had failed to spot that 80' at 81 (A) would get black 80 gaining a liberty and killing outright. EndCom VAR W 1 c17 B 2 b16 ENDVAR B 81 c17 W 82 b17 B 83 c18 W 84 a13 B 85 d18 Mark A@a11 #22 Com Black 85: (S) Should be at 88 (A), followed by white 207, black 208, white 211, black 214, white 209, black 216 leading to a ko which is favourable for Black (See variation). (M) Probably black would end up killing six white cutting stones (22 etc) with his ko threat. This would be very good for Black.

EndCom B 91 g7 Com Black 91: (M) Much better to leave this group for aji - it is white's only territory even if dead. EndCom W 92 f6 B 93 j8 Mark A@k7 B@h4 Com Black 93: (S) Too heavy. 132 (A) is better shape, or try sacrificing with 110 (B) perhaps.

After black 123 (B) white is completely out of control.

EndCom W 144 o9 B 145 h1 W 146 g2 B 147 q7 W 148 j1 Mark A@p6 Com White 148: (M) Unnecessary - 174 (A) is enough to live, then White would still have chances.

It turned out to be seki. Black's lead survived the accidental loss of the upper left group during byo-yomi.
