Mastering Prophylaxis Like Karpov

Prophylaxis is the art of asking "What does my opponent want to do?" before deciding your own plan. It is not purely defensive, prophylactic moves often improve your own position while preventing the opponent's counterplay. The result: the opponent has no constructive plan and is reduced to waiting while you accumulate advantages.

1. Identify the opponent's plan. What pawn break are they aiming for? What piece manoeuvre? What attack?
2. Prevent it. Place a piece to block the break, control the square the opponent's piece wants to go to, or make a prophylactic pawn move that takes the sting out of the opponent's plan.
3. Improve your position. While the opponent's plan is neutralised, quietly improve your pieces, create weaknesses, and prepare your own operation.
4. Strike when ready. Once the opponent is completely tied down, execute your plan, usually a pawn break or piece sacrifice that the opponent can no longer prevent.

• h3/a3: Preventing a bishop pin (Bg4 or Bb4).
• Kh1/Kh8: Removing the king from a potential check or X-ray.
• Controlling key squares: Placing a piece on a square the opponent needs for their plan.
• Prophylactic pawn moves: a4 to prevent ...b5; f3 to support e4; h3 to prevent ...Ng4.

After every opponent move, spend 10 seconds asking: "What does this move threaten? What is their plan?" Only then generate your own candidate moves. This habit alone, considering the opponent's intentions first, will improve your play by 100-200 rating points. Study Karpov's games in the legends archive.
