Queens make things happen
When it comes to the courts, it sometimes helps to think of a real court. King = the person who comes up with the ideas, and gives orders "Let's do this." The director of the movie, the motivator, as it were. Knights spread the King's commands far and wide. They are his voice, ready to argue/battle for their kingdom. Pages, trusted only with carrying quick messages, are students, learning all there is to know about their suit.
Can you see who's missing? That key part? Where is the person who takes the King's ideas and makes them real? The one to hire the architect and get the materials to build the palace the King is envisioning; the person who arranges for a set, film, actors and food services so the director can make his movie? Behold, the Queen. Mom to the King's dad if you like. "You want us to go camping, dear? What a grand idea...we'll need a tent, food, insect repellant..."
Putting it another way, if the King is the captain of the ship saying "We go here," the Queen is the one steering the ship. Once a Queen knows where the ship is going, she'll know, intuitively, how to get there. And, like water heading from mountain top to the ocean, she won't stop till she get's her ship there.
