}
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.}
1...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.Nf3
{B27 Sicilian Defense / King's Knight Variation. White's normal response prepares d4 and avoids such committing moves as
f4 or d3 or Nc3, which have their own rationale.}
2...Nc6
{B30 Sicilian Defense / Nc6 Variation. Black can tip his hand with 2... d6 or e6, but the Knight move is useful in
virtually all Sicilians.}
3.Nc3
{B30 Sicilian Defense / Nc6 Variation.}
3...e6
