Larsen’s Opening
MICOS Opening Group A01.LA – Larsen’s Opening begins with 1.b3. Named after Danish Grandmaster Bent Larsen, the opening is associated with hypermodern ideas and the early fianchetto of White’s queen’s bishop. The move 1.b3 prepares Bb2, where the bishop can influence the central squares and place pressure along the long diagonal toward Black’s kingside. Larsen was influenced by Aron Nimzowitsch, who often used related setups with Nf3 followed by b3.
