When I imagine an extra stone on the board I don’t see it.
You say you don’t see it, but surely you know the exact board location. Perhaps you don’t (consciously) visualize a stone there but instead look at the spot and get a certain tactile sensation?
I would call that visual+tactile, which are the same two modalities Einstein described thinking in. The parenthetical was to cover the possibility that the visualization happens, but it’s so fast that you don’t notice it (I’m assuming there’s a soft threshold between conscious and unconscious thought, not a sharp dividing line).

Yep. Not sure where you’re driving at with that parenthetical though...
