What is Indian Defense?

Indian Defense refers to a group of chess openings characterized by the moves 1.d4 and 2.c4, where Black usually aims to control the center squares e4 and d5 with pieces, rather than occupying them with pawns. This strategic approach typically results in more complex and less symmetrical positions. Some popular examples of the Indian Defense include the King's Indian Defense, the Queen's Indian Defense, and the Nimzo-Indian Defense.
