The Modern Defense arises after 1.e4 g6 and falls under ECO code B06. 1...g6 is the Modern defence, also known as the Robatsch defence after Karl Robatsch . Black prepares to fianchetto their bishop to g7. It is a hypermodern opening: Black allows White space and a classical centre, hoping to undermine it later. This is a similar idea to the Pirc, 1...d6 . In the Pirc player wants to play Nf6 and pressure e4, but needs d6 first to prevent White from playing e5!. In the Modern, Black delays a decision on the g8 knight and so doesn't need to commit to d6 just yet. They prioritise the fianchetto with with 1...g6 and 2...Bg7 instead (but d6 and Nf6 may come later). White usually takes the centre with 2. d4 and Black completes the fianchetto with 2...Bg7. After that White has options: usually 3. Nc3 d6 follows, but since Black hasn't played Nf6 to threaten e4, White can try 3. c4, obtaining structure normally seen against the King's Indian defence, or 3. Nf3. The first modern defences were played in the 19th century and involved 1...g6 and 2...e6 setup. That setup was horrible at a time when people were used to playing open, tactical games, and as a result, 1...g6 was considered to be a very bad opening. Its reputation was sealed when Wilhelm Steinitz beat Augustus Mongredien's Modern defence in under 30 moves. No one knew how to use its flexibility and dynamism to its potential. With 55,535 games in the master database, it is a well-established opening choice.

Common Mistakes to Avoid
- Neglecting development: In the Modern Defense, 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.
- Allowing White to build an overwhelming center: Hypermodern openings allow White space in the center, but you need to strike back at the right moment. Delaying the counterattack too long can leave you without active play.
- Playing without a plan: Each position in the Modern Defense 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.
