Re: [gnugo-devel] regression tests questions (2)

Hello

Another bunch of failures of my patch where i m not sure that the proposed 
move should be considered wrong. (there are many other where no doubt is 
possible)
The proposed moves are always quite big (this is the patch effect). 

The aim is not to trick the tests, but just to have a better understanding of 
where my patch fail, so i can improve it. (i already have some clues ;)

If stronger players agree with some of this, i can open a ticket with patch 
for the corresponding testcases, adding a new possible answer.

seki:806        FAIL    A2      [C1]    , A2 good : got seki too.

niki:1          FAIL    H3      [E17]   , fuseki, rotten situation. 
                                mv 18 W at D17 is wrong direction, C16 was 
right.
                                I propose to remove this testcase.

ninestones:630  FAIL    B11     [F5|H7] , B11 makes life and threat points too

strategy5:226   FAIL    S3      [F5]    , rotten situation. 
                                S3 is life, and gg378 wants it from move 46 
(here 54)!

nngs:2040       FAIL    B4      [E5]    , E5 can lead to semeai for d2 dragon,
                                         not sure what happens after B e5 W b2

trevora:130     FAIL    B7      [F4]    , B7 seems bigger and winning move.

lazarus:13      FAIL    M12     [R13|M8|L9]     , M12 maybe as good as others

13x13:76        FAIL    J6      [K6|L6|J3]      , j6 seems good too, probably 
shape pb.

arend:29        FAIL    E17     [B14|C14]       , e17 seems good too, lots of 
aji

arend:35        FAIL    F15     [H17|J19]       , f15 seems HUGE too

handtalk:7      FAIL    K3      [R4]    fuseki,  maybe r4 urgent ?
                                        k3 big too, then r4 become huge.

ninestones:370  FAIL    E12     [R5]    , difficult. white alive anyway.
                                R5 gote, is good if shibori on R13 S13 is 
played,
                                E12 takes sente elsewhere.

nngs3:310       FAIL    E6      [B5|B7|D7|C4]   , E6 seems good too.
                                 maybe it has another aim than proposed 
solution.

nngs4:770       FAIL    N16     [Q2|C13|L3|L4|K4|F16|F17] N16 good too,
                 better than Q14 like requested. 22.69 points >= K3 21.99 which 
is solution.
                 /* Question : F15 is valued 17.56, F16 F17 zero !!! It seems 
wrong to me.
                  * Where do this come from ?.
                  * This makes the twin going wrong in other similar cases 
                  */

gifu03:603      FAIL    F12     [B16]   , F12 seems as good, 20 points maybe 
more, 
                                        and it has big followup, when b16 has 
none.
