Quoting Lars Schäfers <[email protected]>:

MyGoFriend plays different from most other programs in the opening, my
guess is that MGF does not suffers from some bias inherent in most MC
programs and thus plays more natural (from human aesthetic point of
view) and stronger moves. perhaps it uses some high quality pattern
matching to bias the tree part and does not use AMAF or RAVE at all.
MGF also had a superko-bug in the exp1 Version. It lost at least 2 games
against Gomorra with illegal moves. That should be easy to fix if not
already done in exp2.

As I read this MyGoFriend lost a game with the super ko bug against Valkyria with exp2. Valkyria had this bug too once in its infancy. Valkyria had a won position so I think so it probably happens only when the program tries to avoid a loss and sacrifices stones to make the game longer. The game is attached.

Best
Magnus
