Theoretical novelty for Nimzo-Indian: Kmoch

Hello, I'd like to share with you a theoretical variation of one of the more tiresome main lines of Nimzo-Indian Defense: Kmoch Variation, line with 6... Qh4+. I also indicated some interesting branches of this system, so that the players less acquainted with this opening can learn something new.

My proposed novelty is on move 16.Qd5 followed with Qb3 if possible. (although 16.Be2 also gives white a better position) I don't have this variation in my game database, maybe someone with a bigger one has? (anyone with Chessbase 12?)

Not sure...Why would you have to move the queen again?

Because it's more useful on b3. I want to do a4 very fast to stop him from advancing his huge queenside majority. Also, if he trades queens it's much better for me, that's why Qb3 is the best if black goes Nc6 since his queen is blocked there and he has to trade.

If as shown, black goes Na6, he can then retreat with queen, but his position is crumbling. I feel like after Bd3, Bc4, a4 and Bxa6 I'm winning this.

If instead of Na6 or Nc6 black goes with for example Re8, he loses d6.

If black goes Qd7 to intercept my Qb3 I put more pressure on d6 with Bf4.

Also, remember, when my queen is on b3 she's still indirectly attacking king and directly b7, so it's hard for black to make a bishop move.

Qd5 is much more agressive than the book Be2.

Not in the main line...

Also why would anybody choose to play this variation? Aside from surprise factor it seems pretty weak.

Woah that’s a cool theme
