King's Gambit Accepted, an Open Game

Not to be confused with the opening of the same name.

An Open Game is where some of the pawns in the center have been traded off. They are important because if a position is open, then long range pieces like the rooks and queens can go through open files and move around easier. Bishops will be more effective than knights in these positions, because the bishop can make use of its long range and attack more squares than the knight. Open games also make it easier for both sides to use tactics.

While the opening named the Open Game isn't an open game, open games deriving from the opening, like the Center Game, Danish Gambit, Evans Gambit, Scotch Game, Italian Game and King's Gambit were common when the opening was named.
