The King's Pawn Game with 2...Nc6 arises after 1.e4 e5 2.Nf3 Nc6. ECO code: C44.

This is the most popular response to 2.Nf3, developing the knight to its most natural square and defending e5. It is the starting point for the Ruy Lopez (3.Bb5), Giuoco Piano (3.Bc4), Scotch Game (3.d4), the Four Knights Game (3.Nc3 Nf6), and many other classical openings. This is the single most commonly reached position in all of chess.
