What is Open Game?

An Open Game in chess is a category of opening systems where the game begins with the moves 1.e4 e5. The term is usually used to describe double King's Pawn Openings, where both players move their king's pawn two squares forward. This leads to an open position, meaning there are few pawns in the center and the potential for tactical, sharp play due to better lines for the bishops, queens, and knights is increased.
