The King's Knight Opening is a chess opening consisting of the moves:
White's second move attacks the e-pawn. Black usually defends this with 2...Nc6, which leads to several named openings. Of the alternatives, the most important are Petrov's Defense (2...Nf6) and Philidor's Defense (2...d6).
Most games (more than 80%) continue with 2...Nc6.
Some moves from here include:
Of the alternatives, 2...Nf6 (Petrov's Defense) is considered fully respectable and is common in grandmaster games. Philidor's Defense is playable but is seen more rarely.
