11 169 B5 seems to be the losing move. This move doesn't make sense.
12 Pachi has been wrongly evaluating both bottom group around S4 (it's just
13 hairy for simulations) and top group around A19 - that one is a bit more
14 interesting, the problem is that black is double likely to play E19
15 (since it's C19 selfatari cousin), but after E19, white will not notice
16 the need to connect at C19. Not sure how to solve this yet, perhaps some
17 way to add cousins to last_move logic...

20 won game lost: 212 H13 should be at J12.

27 leading up to 90% then lost.
28 bad evaluation of 3 areas according to pasky.
30 * http://files.gokgs.com/games/2011/5/25/pachi2-Zen19S.sgf
31 lost but was leading according to ajahuang and Zen itself
33 * http://files.gokgs.com/games/2011/2/20/ramesses2-pachi2.sgf
34 good example of losing a won game.
36 * http://files.gokgs.com/games/2011/2/18/pachi2-tf-3.sgf seki
37 lost because of unrecognized seki

40 threw away a won game. pachi thought until the end that top left
41 white group was dead, so it made silly moves elsewhere.
42 The playouts must be prevented from filling the eye at A17.
44 * http://files.gokgs.com/games/2011/6/10/pachi30s-samba-2.sgf falseeye
45 exactly the same problem as botkiller2-pachi30s.sgf:
46 pachi considers the top left black group as unsettled
47 although it is clearly alive. So it makes silly moves
48 elsewhere. We have to fix this bug, it is too frequent.
50 * http://files.gokgs.com/games/2011/6/9/jinen-pachi30s-2.sgf ko
51 move 165 G5 again playing the ko threat before the ko.
52 move 187 R18 is not a ko threat
54 At this point pachi still considers the top right as
55 unsetled, although it is is clearly lost for B. So pachi's
56 estimate of winning by 61% is way too optimistic.
58 * http://files.gokgs.com/games/2011/6/14/pachi2-Regenbogen.sgf
59 pachi doesn't see that bent four in top left corner is dead.
60 Still thinks it is winning 79% at move 250 G4.
62 * http://files.gokgs.com/games/2011/6/14/pachi2-cdocdo-3.sgf semeai
63 pachi loses every semai by a large number of liberties
64 but still considers itself winning 57% up to move 222 G16.
66 * http://files.gokgs.com/games/2011/6/13/pachi30s-Jep.sgf ladder
67 moves 102..108 playing a broken ladder
69 * http://files.gokgs.com/games/2011/6/18/dorabon-pachi2-4.sgf semeai falseeye
70 pachi considers the bottom left semeai won by black (but black
71 loses it) and the bottom right as undecided (white is clearly
72 alive). At move 270 L4 it still thinks it is leading by 80%
73 although the game is lost.
74 The bottom right is the same problem as
75 http://files.gokgs.com/games/2011/6/10/pachi30s-samba-2.sgf
76 and http://files.gokgs.com/games/2011/6/9/botkiller2-pachi30s.sgf
77 This corner shape is very frequent and pachi always gets it wrong.
79 * http://files.gokgs.com/games/2011/6/18/pachi2-ultimakang-4.sgf
80 pachi was winning up to move 230 Q14 big mistake. Win ratio dropped
81 from 60% to 25% at next move.
83 * http://files.gokgs.com/games/2011/6/18/akkannbee-pachi2.sgf seki
84 pachi totally confused by very simple seki.
86 * http://files.gokgs.com/games/2011/7/6/xiaosugi-pachi2.sgf seki
87 pachi thinks until the end that it wins by 80% because it
88 doesn't understand the seki in lower right. It should have lost
89 by 42.5 points but white mistakenly agreed to treat the seki as dead.
91 * http://files.gokgs.com/games/2011/7/5/pachi2-azlan7-2.sgf
92 move 84 E10 & 86 F10 big mistakes, leave white group dead.
93 (amazingly pachi recovered and azlan7 escaped in the end).
95 * http://files.gokgs.com/games/2011/7/5/fafahhhh-pachi2.sgf
96 threw away won game, probably because of complex corner situations
97 won by time but game was lost on board
99 * http://files.gokgs.com/games/2011/7/3/pachi2-oasis7.sgf
100 Passed even though a dead opponent group was marked alive.
102 * http://files.gokgs.com/games/2011/7/28/pachi2-Novicer.sgf falseeye
103 Pachi makes many stupid moves because it thinks the top left
104 corner is unsettled although it is clearly alive. This shape
105 (4 in a row) is so simple that it should get it right.
108 W 264 E19 doesn't make sense, but still 69%
109 W 266 H19 doesn't make sense, but still 61%
110 W 268 T9 should be T8
111 W 292 A17 50%, W 294 R6 37% shows that top left was not
113 Also false eye evaluation problem in bottom left.
115 * http://files.gokgs.com/games/2011/7/28/pachi2-pkunzip-2.sgf ladder
116 W 132 C9, W 134 B8, W 136 A8 plays a broken ladder but win ratio 52%
117 so it should not play desperate moves.
118 Pachi thought it was winning 72% at W 198 M3 but lost the game.
120 * http://files.gokgs.com/games/2011/7/16/ihatebots-pachi2.sgf semeai
121 pachi threw away the game because it didn't evaluate the
122 semeai in bottom left correctly.
124 * http://files.gokgs.com/games/2011/7/31/pachi2-Drogba987.sgf
125 B 28 H4 should be at F1 or G1 to save E2 & E3 and the game.
126 Pachi usually finds this so I'm surprised it didn't get it here.

135 move 143 N19: pachi extends a losing ladder
136 This ladder bug seems more frequent since e9df2b6 (even though
137 this change made Pachi 40 elo stronger).
139 * http://files.gokgs.com/games/2011/8/10/jerryfish-pachi2.sgf semeai
140 lost even game against 3k. Win ratio drops from 61% at 117 N1
141 to 49% at the next move. So pachi didn't evaluate the semai correctly.

144 Pachi hallucinated again on bottom right corner.
145 This is the same problem as
146 http://files.gokgs.com/games/2011/6/18/dorabon-pachi2-4.sgf
147 http://files.gokgs.com/games/2011/6/10/pachi30s-samba-2.sgf

152 Move 51 onwards: pachi plays a broken ladder, which almost cost the game.
153 This might be the same bug as
