[gnugo-devel] Some blunders

[max-d]

Hi ,
waiting for Handtalk to arrive (by legs ?) , i have run a 5 game match
between
-Gnugo 3.4
-Cosmic Gnugo
-Go ++
-Winhonte

-Gnugo level = 13
-Go++ level is 5 (the higher)
-WH 14-12-8 (default is 10-8-4)

some results
C GG-GG3.4 : 2-3
GG3.4-Go++: 2-3
Go++-C GG:  2-3
(games with WH are not finished yet)

here are 2 games between cosmic and go++ (see the files below. warning :
colors are alternated)

game 3
Cosmic being ahead by far ...
then a hudge blunder at move 101

101 gnugo_3.4: = E5
= E5 20.00 H2 16.47 B2 15.78 G3 14.77 D1 13.39 F1 13.13 G19 6.04 G1 6.03 H1
5.34 M18 3.14 (*top_moves*)

All GNUgos do so !

2/ still an Invasion problem
game5
(Cosmic again leads by far ,but just miss to loose )
After black 111 all gnugos (3.0 ,3.2, 3.4, 3.3.19, 3.3.16, cosmic) never
even consider  the MORE NATURAL  move : 112 N6
Any beginner would think  at N6 first !
This fact seems to show that there is some (wrong) instructions which try to
say GG not to play as a beginner...

112 gnugo_3.4: = M6
= M6 20.84 M5 16.36 N5 12.88
N7 12.20 L6 12.06 M7 10.95 L5 10.45 K8 5.61 E15 3.11 G14 2.42 (*top_moves*)

Of course, Cosmic should have played Q3 Q4 or P3 far before this state of
the game (but all GNUgos misplay this) .

Once these invasion problems are fixed i do not see how Go++ / WH can beat
GNUgo !

3/ about influence ...
I have some curious differences between black and white influence treatment
.
I have put 2 pictures here (blue =territorry ,green= moyo , brown
=influence)
