Parent Queen's Pawn Game

Indian defences are chess openings characterised by the moves:

They are all to varying degrees hypermodern defences, where Black invites White to establish an imposing presence in the centre with the plan of undermining and ultimately destroying it. Although the Indian defences were championed in the 1920s by players in the hypermodern school, they were not fully accepted until Russian players showed in the late 1940s that these systems are sound for Black. Since then, the Indian defences have become a popular way for Black to respond to 1.d4 because they often offer an unbalanced game with winning chances for both sides. Transpositions are important and many variations can be reached by several move orders.

The usual White second move is 2.c4, grabbing a larger share of the centre and allowing the move Nc3, to prepare for moving the e-pawn to e4 without blocking the c-pawn with the knight. Black's most popular replies are

but other moves are played as detailed below.

Instead of 2.c4, White often plays 2.Nf3. Then Black may play 2...d5 which may transpose to a Queen's Gambit after 3.c4. Or Black may play which retains possibilities of transposing to a Queen's Gambit or Queen's Indian Defence. Alternatively 2...g6 may transpose to a King's Indian Defence or Grünfeld Defence, while 2...c5 invites transposition to a Benoni. White can deny Black any of these transpositions by refraining from c2-c4 over the next several moves.

On the second move, White can also play 2.Bg5, the Trompowsky Attack. Black can respond 2...Ne4 (see ), or 2...e6 (see ), among other moves. A third alternative for White is the rarer 2.Nc3. Then Black may play 2...d5, after which 3.Bg5 is the Richter-Veresov Attack (D01, see ). Black may also play 2...g6 (see ).


Advocated by Nimzowitsch as early as 1913, the Nimzo-Indian Defence was the first of the Indian systems to gain full acceptance. It remains one of the most popular and well-respected defences to 1.d4, and White often chooses move orders designed to avoid it. Black attacks the centre with pieces and is prepared to trade a bishop for a knight to weaken White's queenside with doubled pawns.
