[gnugo-devel] Gnu Go 3.2 possibly correctable flaw in play

[Stephen123]

I noticed a possibly correctable flaw in Gnu Go 3.2 opening strategy.  The 
SGF file below shows the problem with Gnu Go's opening.  I can use the same 
flaw 
to give Gnu Go 6 stones and still win, even though I'm not that good.  This 
trick of sacraficing a couple of stones to waste a lot of the programs stones 
works against Swiss Explorer and Goliath also, but doesn't work against human 
players.  This looks to me like a straightforward flaw that might not be too 
hard to fix.
