Indian Defence

In the game of chess, Indian Defence or Indian Game is a broad term for a group of 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. It is also possible to transpose into classical openings such as the Queen's Gambit and the Slav Defence; these are not considered "Indian" openings.
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 ).
History.
The earliest known use of the term "Indian Defence" was in 1884, and the name was attributed to the openings used by the Indian player Moheschunder Bannerjee against John Cochrane. Philip W. Sergeant describes Moheschunder as having been as of 1848 "a Brahman in the "Mofussil"—up country, as we might say—who had never been beaten at chess!" Sergeant wrote in 1934 (substituting algebraic notation for his descriptive notation):The Indian Defences by g6 coupled with d6, or b6 coupled with e6, were largely taught to European players by the example of Moheschunder and other Indians, to whom the fianchetto developments were a natural legacy from their own game. The fondness for them of the present Indian champion of British chess, Mir Sultan Khan, is well known. But they are now so widely popular that Dr. S. G. Tartakover was able to declare, some years ago, that "to-day fianchettos are trumps." A sequel hardly to have been anticipated from the discovery of Moheschunder in the "Mofussil"!
In the following game, Moheschunder (Black) plays the Grünfeld Defence against Cochrane in 1855—some 38 years before Ernst Grünfeld was born.
Another of the games between these players transposed to what would today be called the Four Pawns Attack against the King's Indian Defence. This time Moheschunder, as Black, won after some enterprising (and perhaps dubious) sacrificial play:
The term "Indian Defence" was popularized by Savielly Tartakower in the early 1920s. In his 1924 book "Die hypermoderne Schachpartie", Tartakower classifies the Indian Defences under the broad headings "Old Indian" (...d6 and eventual ...g6) and "Neo-Indian" (...e6 and eventual ...b6). Under the heading "Old Indian", he considers the openings now known as the King's Indian and Grünfeld Defences. He also proposes the names "Proto-Indian" for 1.d4 d6, "Pseudo-Indian" for 1.d4 c5, "Semi-Indian" for 1.d4 Nf6 2.Nc3 and "Three Quarter Indian" for 1.d4 Nf6 2.Nd2, none of which came into wider use.
The modern names "King's Indian Defence", "Queen's Indian Defence", "Old Indian Defence" and "King's Indian Attack" were attributed by Richard Reti to Hans Kmoch, though Reti himself did not approve of these terms. Reti also attributed to Kmoch the terms "All Indian Defence" (where Black fianchettoes both bishops after 1.d4 Nf6) and "Queen's Indian Attack" (where White opens 1.Nf3 and 2.b3) but these did not come into general use.
Main lines beginning 2.c4.
2...e6.
Nimzo-Indian Defence: 3.Nc3 Bb4.
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.
Queen's Indian Defence: 3.Nf3 b6.
The Queen's Indian Defence is considered solid, safe, and perhaps somewhat drawish. Black often chooses the Queen's Indian when White avoids the Nimzo-Indian by playing 3.Nf3 instead of 3.Nc3. Black constructs a sound position that makes no positional concessions, although sometimes it is difficult for Black to obtain good winning chances. Karpov is a leading expert in this opening. Many Queen's Indian Defence players also play the Nimzo-Indian Defence, and in fact the line 3.Nf3 b6 4.Nc3 Bb4 is sometimes called the "Nimzo/Queen's Indian Hybrid" or similar, and could be classified under either opening.
Bogo-Indian Defence: 3.Nf3 Bb4+.
The Bogo-Indian Defence is a solid alternative to the Queen's Indian, into which it sometimes transposes. It is less popular than that opening, however, perhaps because many players are loath to surrender the (particularly without doubling White's pawns), as Black often ends up doing after 4.Nbd2. The classical 4.Bd2 Qe7 is also often seen, although more recently 4...a5!? and even 4...c5!? have emerged as alternatives. Transposition to the Nimzo-Indian with 4.Nc3 is perfectly playable but rarely seen, since most players who play 3.Nf3 do so in order to avoid that opening.
Blumenfeld Countergambit: 3.Nf3 c5 4.d5 b5.
The Blumenfeld Countergambit bears a superficial but misleading resemblance to the Benko Gambit, as Black's goals are very different. Black gambits a wing pawn in an attempt to build a strong centre. White can either accept the gambit or decline it to maintain a small positional advantage. Although the Blumenfeld is playable for Black it is not very popular.
Catalan Opening: 3.g3.
The Catalan Opening features a quick of White's .
2...g6.
Grünfeld Defence: 3.Nc3 d5.
Ernst Grünfeld debuted the Grünfeld Defence in 1922. Distinguished by the move 3...d5, Grünfeld intended it as an improvement to the King's Indian which was not considered entirely satisfactory at that time. The Grünfeld has been adopted by World Champions Smyslov, Fischer, and Kasparov.
King's Indian Defence: 3.Nc3 Bg7.
The King's Indian Defence is aggressive and somewhat risky, and generally indicates that Black will not be satisfied with a draw. Although it was played occasionally as early as the late 19th century, the King's Indian was considered inferior until the 1940s when it was featured in the games of Bronstein, Boleslavsky, and Reshevsky. It was Fischer's favoured defence to 1.d4, but its popularity faded in the mid-1970s. Kasparov's successes with the defence restored the King's Indian to prominence in the 1980s.
2...c5.
Benoni Defence.
The Benoni Defense is a risky attempt by Black to unbalance the position and gain active piece play at the cost of allowing White a pawn wedge at d5 and a central majority. The most common Benoni line is the Modern Benoni (3.d5 e6 4.Nc3). Tal popularised the defence in the 1960s by winning several brilliant games with it, and Bobby Fischer occasionally adopted it, with good results, including a win in his 1972 World Championship match against Boris Spassky. Often Black adopts a slightly different move order, playing 2...e6 before 3...c5 in order to avoid the sharpest lines for White. 
Benko Gambit (or Volga Gambit): 3.d5 b5.
The Benko Gambit (known as the Volga Gambit in Russia and Eastern Europe) is one of Black's most popular ways of meeting 1.d4, though it is less common at elite level. Black plays to open lines on the queenside where White will be subject to considerable pressure. If White accepts the gambit, Black's compensation is positional rather than tactical, and his initiative can last even after many piece exchanges and well into the endgame. White often chooses instead either to decline the gambit pawn or return it.
Other 2nd moves for Black.
Old Indian Defence: 2...d6 3.Nc3 e5.
The Old Indian Defence was introduced by Tarrasch in 1902, but it is more commonly associated with Chigorin who adopted it five years later. It is similar to the King's Indian in that both feature a ...d6 and ...e5 pawn centre, but in the Old Indian Black's king bishop is developed to e7 rather than being fianchettoed on g7. The Old Indian is solid, but Black's position is usually cramped and it lacks the dynamic possibilities found in the King's Indian.
Budapest Gambit: 2...e5.
The Budapest Gambit is rarely played in grandmaster games, but more often adopted by amateurs. Although it is a gambit, White cannot hold on to his extra pawn without making compromises in the deployment of his pieces, so he often chooses to return the pawn and retain the initiative.
