The Open Games (1...e5) arises after 1.e4 e5 and falls under ECO code C20. 1...e5 is the Open game (or the Double King's Pawn game). It is Black's classical response to 1. e4. By mirroring White's move, Black grabs an equal share of the centre and scope to develop some pieces. 1...e5 is also one of the few moves that directly interferes with White's ideal plan of playing d4. But, the move's merit is also a drawback: the longer the position remains symmetrical, the longer White will have an advantage by moving first. Though the move is still common at every level, it saw a modest decline in popularity during the 20th century. Black's pawn on e5 is undefended, so it is easy for White to develop in a way that restricts Black's possible responses by threatening to capture it. This is White's most common plan, but they may also chose to develop without attacking. White may attack Black's undefended e5 pawn. By attacking, White keeps the initiative: Black is forced to react to White's plans or they could lose the pawn. With 464,268 games in the master database, it is one of the most popular opening choice.

Common Mistakes to Avoid
- Neglecting development: In the Open Games (1...e5), it can be tempting to make extra pawn moves early on. However, falling behind in development can be punished quickly, especially in open positions where opponent pieces can find active squares.
- Playing without a plan: Each position in the Open Games (1...e5) demands a specific approach. Understand whether you should be attacking, defending, or maneuvering before making your move. Random moves lead to random results.
- Forgetting about piece coordination: Chess pieces are strongest when they work together. A single piece attacking alone is easy to defend against, but coordinated pieces can create unstoppable threats.
