I played a lot of game with pachi 9.01 ( about 100) and only recently I
came to win about one half of the games.
When I tried pachi 9.99  (two weeks ago) I played 5 games and won them all,
besides I killed big
groups, something that never happened with the 9.01 version. So I tried to
install the pattern and as I failed
I went back to the version 9.01 and lose one half on the games (so I did
not improve unfortunatly).
I don't know if this has to do something with my style of play, but at
least against
me pachi 9.01 is in  my opinion more than one stone stronger than the 9.99

Hehe congrats! I saw  one game versus Zen and it was really good, even if
it seems
that pachi was tenukiing to much and could have loose a big part.
