Update: I played some games at the "hard" level, and that erratic behavior of the handicap system doesn't cease to amaze me. Just some minutes ago, I started a game at the "very easy" level and I got almost half the board full of red squares. Of course I won quite easily, but then I started another game at the "easy" level... and I got more than half the board full of green squares! How does this make any sense?!?
