This opening is named after two famous chess players, Aron Nimzowitsch and Bent Larsen. Nimzowitsch was one of the leading chess players in the world in the 1920s and early 1930s, and Larsen was one of the strongest players in the world in the 1960s and 1970s.

The Nimzovich-Larsen Attack Dutch Variation is a flexible and aggressive opening. White's first move, 1. b3, is designed to control the center from a distance and prepare to fianchetto the bishop to b2. The Dutch Variation specifically arises when Black responds with 1...e5, staking a claim in the center.

Here are some reasons why to play the Nimzovich-Larsen Attack Dutch Variation:

1. Flexibility: White's setup is flexible and can be adapted to suit many different types of positions. The fianchettoed bishop on b2 can be a powerful piece in many situations.

2. Avoiding Main Lines: This opening is not as common as some other openings, so you may be able to take your opponent out of their comfort zone and avoid a lot of theory.

3. Control of Center: White controls the center from a distance, which can lead to unique and complex positions.

4. King Safety: White's king is usually quite safe, as Black's central pawns can often block the lines for a quick attack.

However, there are also some reasons why you might not want to play the Nimzovich-Larsen Attack Dutch Variation:

1. Slow Development: White's development can be a bit slow, as it takes a few moves to get the bishop to b2. This can give Black time to launch a quick attack or seize the center.

2. Less Forcing Lines: This opening doesn't have as many forcing lines as some other openings, so it can be harder to get a clear advantage if your opponent plays well.

3. Requires Understanding: To play this opening well, you need to have a good understanding of positional chess, as many of the positions that arise are complex and require careful handling.

4. Rare in High-Level Play: The Nimzovich-Larsen Attack is not seen very often in high-level play, which might indicate that it's not as strong as some other openings.

In conclusion, the Nimzovich-Larsen Attack Dutch Variation is a solid choice for players who prefer positional play and are looking for a flexible and slightly offbeat opening. However, it might not be the best choice for players who prefer tactical play or who are looking for a more aggressive opening. As with any chess opening, it's important to study the typical plans and strategies associated with it to determine if it's a good fit for your playing style.
