Indian Defence
Hypermodern openings include the Réti Opening, King's Indian Defence, Queen's Indian Defence, Nimzo-Indian Defence, Nimzowitsch Defence, Grünfeld Defence, Bogo-Indian Defence, Old Indian Defence, Catalan Opening, King's Indian Attack, Alekhine's Defence, Modern Defence, Pirc Defence, Larsen's Opening, and to a lesser degree the English Opening. Openings such as 1.a3 do not constitute hypermodern openings since, although they delay the occupation of the centre with pawns, they also delay piece .
