Body: <p>In the London system, playing early Nd2 is recommended to react against Qb6. For example if we take this move order</p>
  <pre><code>       [FEN &quot;&quot;]
         1. d4 d5 2. Bf4 Nf6 3. e3 c5 4. c3 Nc6 5. Nd2 Qb6 6. Qb3 c4 7. Qc2 g6 {[%draw arrow,c8,f5,red]} 8. e4
  </code></pre>
  <p>White has managed to stop the <strong>Bf5</strong> and at the same time managed to break open the center</p>
  <p>Now if we look at this move order</p>
  <pre><code>       [FEN &quot;&quot;]
         1. d4 d5 2. Bf4 Nf6 3. e3 c5 4. c3 Qb6 5. Qb3 c4 6. Qc2 g6 {[%draw arrow,c8,f5,red]}
  </code></pre>
  <p>Now notice that black didn't include <strong>Nc6</strong> so white is 1 tempo short of breaking with <strong>e4</strong>. Black will manage to chase the Queen with <strong>Bf5</strong> (possible to c1?) and will complete the development as usual.</p>
  <p>So how should I react when the Queen comes out early as above? Am I left with no choice but to play with the queen on c1</p>

Title: London system move order nuances Qb6 without Nc6
ThreadText: # London system move order nuances Qb6 without Nc6
  
  (Asked by: username_0 on 2023-07-01)
  
  In the London system, playing early Nd2 is recommended to react against Qb6. For example if we take this move order
         [FEN ""]
         1. d4 d5 2. Bf4 Nf6 3. e3 c5 4. c3 Nc6 5. Nd2 Qb6 6. Qb3 c4 7. Qc2 g6 {[%draw arrow,c8,f5,red]} 8. e4
  
  White has managed to stop the Bf5 and at the same time managed to break open the center
  Now if we look at this move order
         [FEN ""]
         1. d4 d5 2. Bf4 Nf6 3. e3 c5 4. c3 Qb6 5. Qb3 c4 6. Qc2 g6 {[%draw arrow,c8,f5,red]}
  
  Now notice that black didn't include Nc6 so white is 1 tempo short of breaking with e4. Black will manage to chase the Queen with Bf5 (possible to c1?) and will complete the development as usual.
  So how should I react when the Queen comes out early as above? Am I left with no choice but to play with the queen on c1

  I think White reacted well when the Black Queen came out. As mentioned by username_1, playing Nf3 earlier, specifically 4.Nf3 in both variations, might make sense.
  
  From Black's perspective, 4..Nc6 and 4..Qb6 are equally good. The only move I do not like is 6..c4 in the first variation. 6..g6 or 6..e6 seem stronger.

  When White is force to play Qc1 he simply develops with Nf3, Be2, h3 and the Bf5 is in trouble after g4. White can play g4 because the black Queen is on the queenside, I guess.
