Nimzowitsch-Larsen Attack

The majority of chess games begin with placing a pawn in the centre. The Nimzowitsch-Larsen Attack takes a different approach. White starts with 1.b3, not touching the central pawns for the moment. The idea is to develop the bishop to b2, where it can look down the long diagonal and put pressure on the centre from a distance. At first, 1.b3 can look a little strange. There is no immediate fight for the centre and no obvious threat. But that’s the point. The position is kept flexible by white while waiting to see how Black chooses to go. This can lead into positional games, or it can also become sharp if the centre opens or both sides. It appeals to those who would rather play a position than spend the first ten moves following a memorised line.

What Is Nimzowitsch-Larsen Opening and It's Features

White plays 1.b3 and follows with Bb2. From b2, the bishop becomes an important part of White's position. Rather than placing pawns in the centre straight off the bat, the bishop is used by white to influence the centre.

For example:

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

There is a solid setup for white, with numerous avenues to go down next. White might play c4, d4, or Nf3, depending on Black's position.

This flexibility is probably the biggest attraction of the opening. You are not committing your entire pawn structure on move one.

There is also a useful psychological side to it. Normally for a players who prepares for 1.e4 or 1.d4, it may become far less comfortable as soon as the game begins with 1.b3. Black gains a playbale position without opening patterns.

Pros

Flexible: White has several ways to develop the position.
Less familiar for many opponents: Black may have to think for themselves earlier.
The bishop on b2 can become very strong: Especially when the centre opens.
Good for positional players: Plans and pisces placement is the key over long theory.
Can transpose into other structures: It doesn't have to stay in the Nimzo-Larsen position.

Cons

Black can take the centre: Black has the opportunity from white to build a pawn centre.
The bishop can lose its bite: If there is a closed centre, the bishops can have fewer useful targets.
It takes patience: White usually does not get an immediate tactical advantage.
Not everything is solved after the first move: White still needs a clear plan for development and the centre.

Nimzowitsch-Larsen Chess Attack History

Aron Nimzowitsch and Bent Larsen are where the name comes from, strong players who studied ideas that challenged traditional views of controlling the centre.

Nimzowitsch led the ideas in hypermodern school. Instead of occupying the centre with pawns, hypermodern players showcased that the centre could also be controlled with pieces from a distance.

White does not rush to put pawns on d4 and e4. But instead, the bishop on b2 influences the centre meanwhile White maintains a flexible pawn structure.

Bent Larsen was one of the best-known players to use the b3 in an elite tournament. Larsen grew famous for playing unusual openings and taking opponents into positions they did not have prepared for.

Nimzowitsch-Larsen Chess Main Variations

There is no single forced variation after 1.b3. That is part of the appeal.

There are several ways for black to respond, after that White chooses a setup.

| Setup | What White is trying to do |

| 1.b3 and Bb2 | Develop the bishop and put pressure on the centre |

| b3 with e3 | Build a solid position and prepare normal development |

| b3 with c4 | Challenge Black's central space from the side |

| b3 followed by d4 | Move into a more traditional central structure |

| b3 against ...e5 | Put pressure on Black's centre and look for a later pawn break |

Some think because the opening starts quietly, White should keep making quiet moves, tjaz is a common mistake.

White needs to fight for useful squares and decide when the time is right to challenge Black's centre. If Black has built a big pawn centre, moves such as c4 or d4 can become important.

The bishop on b2 is also worth keeping an eye on. When the centre opens, it can suddenly become one of White's best pieces. A diagonal that looked harmless a few moves earlier can become very powerful once the pawns move.

How to counter Nimzo-Larsen Attack

A special trick is not required to play against the Nimzo-Larsen Attack. For a lot of positions, Black can develop normally and take advantage of the fact that White has not occupied the centre yet.

Moves such as ...e5 and ...d5 can give Black plenty of space. Developing the knights and bishops and getting the king safe are usually more important than trying to refute 1.b3.

There is one thing Black should be careful about, though: building a large centre and then assuming it cannot be challenged.

White's pieces are designed to put pressure on that centre. The bishop on b2 is one part of the plan, while pawn breaks can attack the base of Black's structure later.

A sensible approach for Black is:

Develop the pieces.
Take useful central space.
Watch the b2-g7 diagonal.
Castle when the position allows it.
Be prepared for White to challenge the centre with c4 or d4.

If Black develops comfortably and keeps an eye on White's central breaks, the opening is perfectly manageable.

For White, the opposite lesson applies. Don't play 1.b3 and then forget about the centre. The opening works because the pieces and pawn breaks eventually put pressure on that centre.

Conclusion

It is not an opening for everyone. But if you like keeping your options open, it is an interesting weapon.

It is simple at its core: play 1.b3, develop Bb2, develop the rest of your pieces, wait for the right moment to challenge the centre. It depends on black what happens next.

That is really the charm of the opening. 1.b3 gives you a different kind of game, a game in which your opponent has to make decisions early into the game, and where understanding the position is more important than knowing a long line of theory.
