1. e4 ... ;B00 King's Pawn Opening. The King's Pawn
;opening move is both popular and
;logical. It controls the center, opens
;lines for both the Queen and the Bishop,
;and usually leads to an open game in
;which tactics, rather than slow
;maneuvering, predominates.
... e5 ;C20 King's Pawn Game. Black responds
;symmetrically, making a direct challenge
;to the central squares.
2. Nf3 ... ;C40 King's Knight Opening. With the
;possible exception of :2. f4, this is
;the most logical second move against
;Black's symmetrical answer to the King's
;Pawn. The Knight attacks e5, clears the
;way for an eventual castle and rests on
;its best defensive square.
... d6 ;C41 Philidor's Defense. The Philidor
;Defense concedes a cramped King's
;Bishop, but is otherwise resilient on
;the Queenside.
3. d4 ... ;C41 Philidor's Defense.
... Nc6 ;C41 Philidor's Defense.
4. dxe5 ... ;C41 Philidor's Defense.
