Answers.Text: 16... b4 is justified when I say "if Black follows the same plan". If not, the position is about equal and 16... Nb6 seems a good move–but not 16... a5 because exd5 and the e-file opening is going to hurt.

Answers.Text: That's true, although I didn't think of a4 as good square for the knight, but to show an example on how to react if Black wants to immediately put pressure on the e4 pawn (i.e., kicking away the defender). Anyways I think you are right, Nb6 seems like a good inclusion!

ThreadText: # What are the White plans in this "copycat" line in the Jobava London?
  
  (Asked by: username_0 on 2022-11-15)
  
  In the last round of last month's [4th EJCOA IM Norm tournament](https://ratings.fide.com/tournament_details.phtml?event=301722) this interesting game was played. White plays the Jobava London and Black plays the "copycat" line with 4...Bf5. Black then plays a manoeuvre to exchange queens.

  What should White's plan(s) be after the queen exchange? It seems to me that White's pieces don't end up on good squares. What setup should White be aiming for?

  The setup with `14.e4` was the correct choice by White as it prevents Nd7-f5 hitting the h4 weakness and restrains the light bishop's activity.
  
  The error was `15.Bh3` because it wastes a tempo by misplacing the bishop in the h3 square, whose active diagonal c8-h3 can be neutralised by evacuating the pieces as in the game.
  
  Instead, the most accurate play for White (according to the engine and my understanding) was to play Nge2 (quickly eyeing the f4 square from where we hit the g6 bishop), and only after Black long castles, then Bh3 is effective.
  
  With this setup, **if Black follows the same plan**, we reach a long-term comfortable position for White with a superior bishop:
