We extend the mode-coupling theory of the viscosity of dense liquids to this case of strong confinement, thus offering a tentative explanation of the growth of viscosity and how it grows as the separation between the surfaces is decreased, and making additional predictions. An important, purely phenomenological, input to our theory is the assumption that confinement makes the bare viscosity tensor of the fluid uniaxial.
