mvc

I understand the role of the model and view in the Model-View-Controller pattern, but I have a hard time understanding why a controller is necessary.

Let's assume we're creating a chess program using an MVC approach; the game state should be the model, and the GUI should be the view. What exactly is the controller in this case?

Is it just a separate class that has all the functions that will be called when you, say, click on a tile? Why not just perform all the logic on the model in the view itself?
