Marginal Advantage implies looking one turn ahead, to determine how the opponent can react to your move. The Greedy approach doesn't have to look ahead at all. The difference is that simple - the more moves you look ahead, the better you play. Chess programs became "expert level" when there was enough CPU horsepower to look 6 moves ahead.
