If we want to be a aggresive Nimzo-Larsener, Then we should get a b6, But if we are even more aggresive, A double fianchetto is what we need!
A interesting alternative to the owen's defense.

Its deadly, And eazy to play!
Soo if we are a aggresive nimzo larsener, We would ideally like a nimzo larsen for black...
But we cant have it!!!
