Modern Defence
The Modern Defence begins after 1.e4 g6. It is one of Black's most flexible replies to 1.e4, and can also be used against 1.d4, appealing to creative counter-attackers who invite White forward before striking back.

Why play the Modern Defence?
Because you are a counter-attacker who wants to lure the opponent forward before striking.
After 1.e4, Black replies with 1...g6 and prepares to fianchetto the bishop to g7. White is invited to build a large centre with e4 and d4, sometimes adding c4 or f4.
Black then tries to prove that White's impressive centre is also a target.
The Modern is a family of setups rather than one narrow opening. It can transpose to the Pirc, King's Indian, Sicilian-style structures, or even Hippopotamus formations.
The move order is flexible, which is both the opening's biggest strength and its biggest challenge.
White has many attractive choices, and that can become a practical problem if the player is used to memorised main lines.
There are real dangers. If Black plays too slowly, White's space advantage can become overwhelming.
The Modern Defence is perfect for players who dislike being predictable and enjoy flexible development, unusual pawn structures, and early independent thinking.

Traps and tactics
Three traps every Modern Defence player should know.
Themes
Counter-strike
The Modern works only when Black chooses the right moment to hit back.
Soul bishop
The bishop on g7 pressures the centre and queenside from a distance.
Space as target
White's centre is a strength if supported, but it becomes a target if overextended.
Delayed knight
Black often delays ...Nf6 to keep flexibility and avoid immediate e5 tempo gains.
History
From Robatsch and British experiments to Tiger's Modern and engine-era surprise value.
1940-1950
Modern identity
Hypermodern ideas are well established, but the pure Modern Defence with 1...g6 is still less common than the Pirc, King's Indian, and related systems.
1950-1970
Influential ideas
Austrian player Karl Robatsch helps popularise the opening, and the system is still sometimes called the Robatsch Defence.
1970-1990
British adoption
Nigel Davies, Tony Miles, Colin McNab, and other British players explore the Modern and add to its theory.
1990-2010
Tiger's Modern
Swedish GM Tiger Hillarp Persson becomes one of the opening's most important champions, especially through queenside ideas with ...a6 and ...b5.
2020s
Age of engines
Engines show that the Modern is playable but risky. At the top level it often appears in must-win situations or faster time controls.

FAQ
The Modern Defence begins with 1.e4 g6. Black prepares Bg7, allows White to build a centre, and later attacks that centre with pawn breaks and piece pressure.
Yes and no. The setup is easy to learn, but the middlegames can be difficult because Black often gives White a lot of space.
Yes, the Modern is sound, but Black must counterattack accurately and avoid passive play.
The Pirc usually includes an early ...Nf6 attacking e4. In the Modern, Black delays ...Nf6 and starts with ...g6 and ...Bg7.
Tiger's Modern is a dynamic Modern Defence setup associated with Tiger Hillarp Persson, often using quick ...a6 and ...b5 ideas.
There is no single best line. White can choose a big centre with d4 and c4, an aggressive f4 setup, or a 150 Attack with Be3 and Qd2.
Karl Robatsch, Duncan Suttles, Tony Miles, Nigel Davies, Colin McNab, Tiger Hillarp Persson, Magnus Carlsen, and many other creative players have used it.
