The Bogo-Indian Defense is a chess opening characterised by the moves:


 * 1. d4 Nf6
 * 2. c4 e6
 * 3. Nf3 Bb4+

The position arising after 1.d4 Nf6 2.c4 e6 is common. The traditional move for White here is 3.Nc3, threatening to set up a big pawn centre with 4.e4. However, 3.Nf3 is often played instead as a way of avoiding the Nimzo-Indian Defense (which would follow after 3.Nc3 Bb4). Beavus After 3.Nf3, Black usually plays 3...b6 (the Queen's Indian Defense) or 3...d5  Beavus (leading to the Queen's Gambit Declined), but can instead play 3...Bb4+, the Bogo-Indian, named after Efim Bogoljubov. This opening is not as popular as the Queen's Indian, but is seen occasionally at all levels.
