The Modern Defense: Robatsch Variation arises after 1.e4 g6 and falls under ECO code B06. Also called the Robatsch Defence after Karl Robatsch, this hypermodern system sees Black fianchetto their bishop to g7, deliberately conceding space and a classical pawn center to White with the plan of undermining it later. The approach shares common ground with the Pirc Defence (1...d6), but differs in an important way: the Pirc commits to ...d6 early because Black intends ...Nf6 to pressure e4 and needs to prevent e5 in response. In the Modern, Black postpones the decision about the g8 knight entirely, prioritizing the fianchetto with 1...g6 and 2...Bg7, though ...d6 and ...Nf6 often follow later. White typically seizes the center with 2. d4, and after 2...Bg7 has several options: the standard 3. Nc3 d6, or since Black has not yet played ...Nf6 to challenge e4, White can try 3. c4 to reach a King's Indian Defence-type structure, or simply 3. Nf3. Historically, 1...g6 appeared as early as the 19th century, usually paired with 2...e6, but in an era that favored open tactical play, this setup was considered weak. Its reputation suffered further when Wilhelm Steinitz defeated Augustus Mongredien's Modern Defence in under 30 moves, and it took decades before players learned to harness the opening's inherent flexibility and dynamic potential. With 78 million Lichess games across all rating levels, it is a well-established opening choice.

Common Mistakes to Avoid
- 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.
