Larsen's Opening (1. b3) - A Fast Guide

Table of Contents

Hey there, fellow chess enthusiasts! Today, I'm excited to dive into the intriguing world of Larsen's Opening (also known as b3 opening, or Nimzowitsch-Larsen Attack). This opening is also actually a personal favorite of mine!

This opening starts out with 1. b3

Larsen's Opening, also known as b3 Opening, or Nimzowitsch-Larsen Attack

This hypermodern opening involves White developing their bishop early to b2, eyeing a long-range attack against Black's kingside, especially the g7 square. It's a fascinating move that sets the tone for an engaging attacking battle.

A Nod to the Masters: Larsen and Nimzowitsch

The opening owes its name to Danish Grandmaster Bent Larsen, a visionary who drew inspiration from the legendary Aron Nimzowitsch, whom we have already talked about (see Nimzowitsch Defense). Hence, it's also known as the Nimzowitsch-Larsen Attack. Larsen, a force in the 1960s chess scene, showcased the potential of this opening.

Speaking of success, let's not forget about Bobby Fischer, who masterfully wielded Larsen's Opening in 1970, playing and winning 5 five games with it. Fast forward to today, you'll see players like Hikaru Nakamura and Richard Rapport occasionally bringing this opening into play. Their games offer a wealth of insights into the evolution and versatility of Larsen's Opening.

Defending Against Larsen’s Opening

So, how do you defend against this opening? The key lies in securing your kingside and being vigilant against any surprise attacks on the g7 square. A strong defense here can neutralize White's initial advantage and pave the way for a counterattack, usually on the center of the board.

For Black, responding to 1.b3 requires careful consideration. The two main responses, 1…d5 and 1...e5, each set a different tone for the game. It's a decision that can significantly influence the ensuing middle game strategies.


White’s main objective is to control the e5 square, typically by trying to place a knight on it. A common variation follows as:

2. Bb2 Nf6 3. e3 Bf5 4. f4 e6 5. Nf3

1. b3 d5 2. Bb2 Nf6 3. e3 Bf5 4. f4 e6 5. Nf3

White intends to control the e5 square when possible, and it proves to be quite annoying for Black. For this reason, Black usually opts for 1…e5.

1… e5

White's strategy against 1.e5 is still to apply direct pressure against the e5 square.

After 2.Bb2, Nc6 3.e3, Nf6 4.Bb5 Black faces problems defending the pawn.

1. b3 e5 2. Bb2 Nc6 3. e3 Nf6 4. Bb5

Here Black can play 4…d6, but that would stunt the dark-squared bishop's development, so Black is compelled to play 4...Bd6.

At this point, White adds another attacker against the e5 pawn:


1. b3 e5 2. Bb2 Nc6 3. e3 Nf6 4. Bb5 Bd6 5. Na3

And White has solid prospects for the game to come.

1. b3 e5 2. Bb2 Nc6 3. c4

3. c4 is another interesting variation, popularized by GM Adhiban Baskaran.

1. b3 e5 2. Bb2 Nc6 3. c4

White attains a solid pawn structure, comparable to the Hedgehog or the Hippopotamus styles.

Example game: Adhiban Baskaran vs David Navara

White's position is solid, and there are no glaring weaknesses. Black may feel better-developed, but White is prepared to counter-strike at a moment's notice.

Larsen's Opening does not usually lead to effortless, fast victories, but it does take Black off-book and away from well-versed opening preparation. White challenges Black to demonstrate their prowess and understanding off chess.

The Understated Efficacy of Larsen's Opening

Despite being the sixth-most popular opening, Larsen's Opening is remarkably sound. Chess engines often give it an equal valuation for both sides after the initial moves. This balanced nature makes it a viable option for players who enjoy a game where strategy and skill are pivotal. I, personally, have lots of success with the Larsen Opening, and I hope that you'll give it a shot!

To wrap it up, Larsen's Opening is more than just a series of moves; it's a window into the strategic depth of chess. Whether you're playing as White or Black, understanding this opening can significantly impact your approach to the game. Keep exploring, keep learning, and most importantly, enjoy every moment on the chessboard!
