There is a bug in pro and swap version, you can win even if you place more than 5 pieces in a line [which is wrong].
It will be fixed tomorrow and also mentioned in the rules [exactly 5 pieces in a line wins].
Chaosu: If white puts one stone to a corner, black will swap and probably win the game. If white doesn't want to lose, he must start with a balanced position.
That's intersting. What is the difference between a classic unit and the plus? I would like to write a new FAQ issue about that but I cannot test it since I don't have WebTV, could you help me with that?
