A knight can move 8 possible ways, so you need 3 bits to encode a
movement.

To convert these 3 bits into relative motion on a board, define
integer board coordinates, then use a lookup table of (delta x, delta
y) pairs to store the coordinate change of each possible move.  All
the elements of these pairs are +-1 and +-2.

The current board position of a piece is just an (x,y) coordinate.
One such pair is enough for a single knight.
