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.
... e5 ;B23 Sicilian Defense / Severino Defense.
;This defense is not recommended for
;Black. Allowing White's f1-Bishop
;unobstructed view of the f7-square is
;not safe in Sicilian formations.
;Secondly, 2...e5 creates a hole in
;Black's pawn structure at d5: The chance
;of Black being allowed to play ...d5 is
;remote.
3. Nf3 ... ;Out of Opening Book. Attacks Black's
;pawn at e5.

;8.e5 Qxh1+ 9.Bxh1 Kxf7 10.Be4 Ke8
;11.Qh5+ Kd8 12.Bxh7, which wins a rook,
;a knight, and a pawn for a queen and
;three pawns. Better is Qd6, leading to
;5.Nc4 Qe6 6.d3 Nf6 7.Bf4 Nc6 8.Nb5 Nd5
;9.Nbd6+ Kd8 10.Bg5+ Be7, which does not
;result in any captures.

;8.O-O b5 9.Bd5 Nge7 10.d4 Nxd5 11.Nxd5
;cxd4 12.Nxd4, which wins a knight and a

;Bc4, leading to 5...d5 6.Bxd5 Qg5 7.Nxf7
;Qxg2 8.e5 Qxh1+ 9.Bxh1 Kxf7 10.Be4 Ke8
;11.Qh5+ Kd8 12.Bxh7, which wins a queen

;Be7 7.Nc4 Kd8 8.Nd6 Nh6 9.Qd5 Nc6 10.O-O
;a6 11.Bxc6 dxc6 12.Nxb7+ Kc7, which wins

;6.Nf3 a6 7.Bc4 Nc6 8.O-O b5 9.Bd5 Nge7
;10.d4 Nxd5 11.Nxd5 cxd4 12.Nxd4, which
;wins a bishop and a pawn for a knight
;and a pawn. This was black's critical
;error in the game. Black did recover,
;but was later mated.
