I think I have won 2 games on the 5x5... Out of who knows how many. The 5x5 is supposedly solved but I have definitely not solved it. What should I be trying to do as black?
Possibly useful: To begin, you might want to focus on simply ensuring that your group lives (achieve 2 eyes) and not worry about winning by score. Once you get better at that, you can start focusing on trying to increase your score by occupying more of the board.
