The King's Knight Opening: Nc6 arises after 1.e4 e5 2.Nf3 Nc6 and falls under ECO code C44. 2...Nc6 is the natural and most common move, combining defence of the pawn with control of the d4 square. Black avoids committing another pawn for now. This is the most common position after two moves in chess. White has several choices for how to reply, which lead to very different games. White usually decides to develop the bishop next. While the usual advice is to "develop knights before bishops", by holding off on Nc3, White retains the option of playing c3 and d4 to take over the centre with pawns. 3. Bb5 , known as the Spanish or Ruy Lopez, is the most popular 1 and theoretical continuation. By pressuring Black's knight, White is indirectly threatening e5 which the knight defends. This usually leads to tough, positional game. The mainline is 3...a6, but there are many viable continuations all intensely studied. With 338,640 games in the master database, it is one of the most popular opening choice.
