Answers.Body: <p>There is a lot of material available, both in books and on the internet, about how to play isolated Queens pawn positions for both sides, but you ask one very simple question that has a short answer. You ask if there is any basis in the pawn structure for White to launch a King-side attack. There is, but is a bit indirect.</p>
  
  <p>If white plays passively, he may very well drift into an inferior endgame, so he needs to find a way to exert some control over the position, using the positive aspects of his pawn structure. Mostly this is that he has more space and more mobility, and he can use these to shift his pieces toward the enemy King. Typical moves include Ne5, Bd3 and Qc2, Bg5, Nc3-e4, Rae1-e3, f2-f4-f5. Even if the attack does not succeed, it will distract Black from his endgame plans. It is true that there are no targets yet for White to focus on, but they can usually be created later on. White must attack, because he really has nothing else to do.</p>
  
  <p>The issue of exchanging the light-square Bishops is not so clear IMHO.
  Whites KB is mobile and plays many useful roles, attacking f7 and h7, preparing the thrust d5. Blacks QB has less mobility and activity, so a trade tends to relieve Blacks game. That being said, if this B can be posted on b7, it restrains the Pd4 and probes the White K-side, so can become very powerful. Rather than advising that it should always be exchanged off if possible, it might be better to say that its role must be given careful consideration.</p>

Answers.Body: <p>In general, the player with more central control has the means to start a successful attack on the opponent's king. This is just a fact of chess, but I'll list a few reasons for it:</p>
  
  <ul>
  <li><p>The player who controls the centre can use the central squares for efficiently maneuvering his pieces across the board. This plays well with a fast attack.</p></li>
  <li><p>Central control provides the player with active outposts for his pieces, that often put them in striking distance to the opponent's king. As you noted, the e5-square works for the knight.</p></li>
  <li><p>Central control gives the player more space, allowing his pieces to comfortably arrange themselves in attacking formation. For example, because of his central control, White can easily put his queen on d3 to set up a battery.</p></li>
  <li><p>Control of the centre restricts the opponent's pieces. This allows the player to not worry so much about counterplay, allowing him to focus on offensive operations.</p></li>
  </ul>
  
  <p>You noted White could also attack on the queenside. This is true, but here's why attacking on the kingside is better:</p>
  
  <ul>
  <li><p>The King is a more valuable target than mere pawns and squares on the queenside.</p></li>
  <li><p>The b1-h7 diagonal let's White create a Q+B battery right to the Black king's castle. There is no such equally powerful opportunity for pressuring the queenside.</p></li>
  </ul>
  
  <p>Finally, Black benefits from exchanging White's light-squared bishop due to the b1-h7 potential battery.</p>

Answers.Body: <p>You are saying that you do not see why White should attack on the Kingside as "White does not have a majority of pawns in the kingside.".
  This assumes that attacking means starting a sort of pawn storm in every case, but that is not correct.</p>
  
  <p>It may sound weird, but in Isolani positions, you have better attacking prospects mostly because your pawn does not get in the way of your attacking pieces. See the illustration below:</p>
  
  <pre>
  <code>
      [FEN "6k1/pp3ppp/4p3/4N3/3P4/1B5Q/PP3PPP/2BRR1K1 w Q - 0 1"]
  
  
  </code>
  </pre>
  
  <p>Here your pieces are just perfectly placed to attack. Your Knight and your Bishop are putting pressure on f7. Your c1 Bishop can quickly move to g6 or even h6. One of your rooks can be transferred to the third rank quickly (on g3 or h3). Attacking is just easier for you. Note that the pieces will carry the attack, not the pawns.</p>
  
  <p>Now imagine the same position with a pawn on e3 instead:</p>
  
  <pre>
  <code>
      [FEN "6k1/pp3ppp/4p3/4N3/8/1B2P2Q/PP3PPP/2BRR1K1 w Q - 0 1"]
  
  
  </code>
  </pre>
  
  <p>This may not seem huge, but your e3 pawn blocks both your Bishop on c1 and prevents any Rook lift to the third rank: your attack is much harder to carry on now.</p>
  
  <p>Carrying the attack is not an easy task though, and you often need to combine an attack on the f7 weakness and a Rook lift along the third rank, topics that I tackle in my post about <a href="https://pawnbreak.com/attacking-with-the-isolated-queens-pawn/" rel="nofollow noreferrer">how to attack with the Isolated Queen's Pawn</a>.</p>
