When the other men are exchanged off, and you remain with a Bishop and
two or three Pawns, it is often proper to keep your Pawns on squares of
a different color from those on which your Bishop travels, as he can
then prevent the opposing King from approaching them. If, however, you
have the worst of the game, it is mostly better then to keep them on the
same color as the Bishop, that he may defend them.

Supposing you have _Pawns only_ at the end of a game, and the adversary
has a Bishop, it is generally advisable to move the Pawns as soon as
possible to squares of a different color from the diagonals on which he
moves.

Do not indiscriminately exchange your Bishops for Knights, or _vice
versâ_. Two Bishops at the finish of a game are stronger than two
Knights, and one Knight generally more useful than a single Bishop.

_Concerning the Knight._--The Knight is at once the most striking and
most beautiful of all the Pieces. The singularity of its evolutions, by
which it is enabled to overleap the other men and wind its way into the
penetralia of the adverse ranks, and if attacked leap back again within
the boundary of its own, has rendered it the favorite Piece of leading
players in every country.

The assault of the Knight is more subtle and dangerous than that of any
other Piece, because he attacks without putting himself _en prise_, and
his attack can never be resisted by the interposition of another man.

At the commencement of a game, the best place for the King's Knight is
at _K. B's 3d sq._; it there attacks your adversary's K's Pawn, if it
has been moved two squares, and offers no impediment to the playing out
