Nimzo-Larsen Attack

The Nimzo-Larsen Attack starts 1. b3. White prepares to put the bishop on b2, where it aims along the long diagonal at the e5 and g7 squares. White gives Black the centre for now and plans to attack it later with pieces and pawn breaks. It is uncommon, so opponents are often unprepared.

  • Bb2 and e3, then Nf3 or f4, with pressure on e5.

Ideas for Black

  • 1...e5 followed by ...Nc6 and ...d5 takes the centre. Defend e5 well, because the bishop on b2 is aimed at it.
