Named after the Russian Grandmaster Efim Bogoljubov, this defense aims to simplify the position through early minor piece exchanges, offering Black a stable structure from the first moves. Although not as popular as other defenses, it has been used by elite players and remains a viable option in modern chess.
What is the Bogo-Indian Defense?
The Bogo-Indian Defense is characterized by the moves 1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+.
