Good to know

Beside: on one of the four squares directly above, below, left or right, in the same room. Diagonally does not count, and neither does through a wall. A window or door in the wall of your square is beside you.
In a corner: on a square of that room where two of its walls meet. The end of a narrow corridor counts too.
