Proof that if you make an anime about ANYTHING in Japan, you can sell it. Go is actually a type of chess-like Othello-ish game where you and your opponent are trying to place chips to surround each other and control the board. So how do you turn this into a anime? Go back in time to a prince whom is being tutored at how to play Go must pit his two teachers against each other to decide who will stay and teach him. Caught in a cheat by his opponent, (I was framed!) the teacher Sai is forced to leave the city, and thus with out Go to play, drowns himself in a river. BUT! His spirit lives on inside the Go board, and when Hikaru touches the board, the two are joined, and now Hikaru has the ability and skill of a master Go player to guide him through the game.
