Modern Defense: Robatsch Variation

B061.e4 g6 2.d4 Bg7

Updated Oct 17, 20263 min read

TL;DR The Modern Defense is the hypermodern cousin of the Pirc: Black delays the knight to f6 and provokes White into building a broad centre that can later be undermined with c5, e5 or Nc6. Flexible move order makes it a practical surprise weapon at every level.

Summary

The Modern Defense: Robatsch Variation arises after 1.e4 g6 2.d4 Bg7 and falls under ECO code B06. Also called the Robatsch Defense 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 Defense (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 Defense-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 Defense 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.

  • Black invites White to build a big pawn center with e4 and d4, then attacks and undermines it with the g7-bishop instead of occupying it.
  • Unlike the Pirc, Black holds back ...Nf6, which lets White consider c3 to blunt the fianchettoed bishop.

History and Notable Players

Among the most prolific practitioners on the White side are Heikki MJ Westerinen (62 games), Michele Godena (54 games), Evgeny Sveshnikov (44 games). On the Black side, notable exponents include Colin Anderson McNab (323 games), Boris Chatalbashev (187 games), Peter Petran (182 games).

Long treated as a sibling of the Pirc - the 1965 edition of Modern Chess Openings still lumped the two together as one system. Canadian grandmaster Duncan Suttles was one of its leading exponents, and it enjoyed a wave of popularity in the 1970s; British GMs Nigel Davies and Colin McNab became its best-known specialists.

Named after: A hypermodern defence that hands White the centre in order to attack it; also known as the Robatsch Defence, after Karl Robatsch.

Notable players: Duncan Suttles, Nigel Davies, Colin McNab, Magnus Carlsen

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.
