The Same Shade?

Imagine a chessboard pattern. Square A is in the top-left area (appearing light). Square B is in the middle (appearing dark due to its surroundings).

Why does this happen?

Now place short diagonal tick marks crossing both lines — but the tick marks on the top line lean right, and the tick marks on the bottom line lean left. Do the two horizontal lines still appear straight and parallel to you? What is this illusion called, and what does it demonstrate?
