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.
... Nc6 ;C44 Queen's Knight Variation. Now, when
;White plays 3.Nc3 (instead of the Ruy
;Lopez), it's the Three Knight's Game; a
;leisurely system.
3. Bb5 ... ;C60 Ruy Lopez (Spanish). This is the Ruy
;Lopez move. It is designed to maintain
;long-term pressure on Black's center. If
;driven away, the King's Bishop will take
;up a position at b3 or c2 to focus on a
;Kingside attack or on the central
;squares.
... a6 ;C60 Ruy Lopez (Spanish) / Morphy
;Defense. This move, popularized by the
;great Paul Morphy, provides Black
;greater flexibility. Black doesn't fear
;4.Bxc6 (see the Exchange Variation).
4. Ba4 ... ;C70 Ruy Lopez (Spanish) / Morphy Defense
;/ Variation 3.Bb5 a6 4.Ba4.
