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.
... c5 ;B20 Sicilian Defense. The Sicilian
;Defense has an ancient lineage. It
;creates an unbalanced position in which
;both sides have full rein for play, and
;allows Black to call the shots at least
;to some extent.
2. Nc3 ... ;B23 Sicilian Defense / Closed Variation.
;The Closed Variation looks toward the
;fianchetto of the King's Bishop,
;restraining the Black d pawn in the
;meantime.
... Nc6 ;B25 Sicilian Defense / Closed Variation
;2.Nc3 Nc6. 95% of the time in the
;Sicilian, White puts his Knight on c3.
;White may yet play the center break d4,
;but for the moment the question is yet
;to be answered. White's second move
;suggests the possibility of NOT playing
;d4, and playing a closed type position
;instead of the slashing, attacking types
;of position more common to the Sicilian.
3. Na4 ... ;Out of Opening Book. Nge2 would have
;been in the Sicilian Defense / Chameleon
;Variation book opening. Threatens
;Black's pawn at c5.
