[gnugo-devel] Funny blunder

[max-d]

In this game GG3.4  lv 12 is correcting Go++ level 5 (top) when it thinks
there is some points to win .
I have often observed some wins  like this funny one .
GG is "helping" Go++ as _white_
After move 245 Black is leading by 5 points...
At this stage , Go++ often plays some hopeless moves like here 246: S19.
The problem is that it does not understand the meaning of its own moves ...
GG does !!
Final result = white +2 (should  have been even larger if there had been a
white living stone  at R13).

(I know Michel Reiss is receiving these messages .
There is no intention at all for me to ironize about Go++ which is very good
work ... Just to point out that GG is  right now a bit ahead in tactical
play ).

BTW, i would like to run some tests against some top current Asian Go
softwares , does any body know how to get them ?
Thanks
