Prophylaxis in Chess: Stopping Your Opponent's Plans

Prophylaxis in chess is the art of stopping your opponent's plans before they even get going. It's one of the hardest skills to master at the board, and that's true at every level, not just for beginners. Where initiative in chess is about pushing your own ideas onto the board, prophylactic moves ask you to slow down and think from your opponent's side of the table first. Below, we walk through a simple habit for building that skill, then look at a conference that puts it into practice.

How to Build the Habit of Reading Your Opponent's Ideas

Here's a piece of advice from one of the strongest chess coaches working today, the Indian grandmaster R. B. Ramesh. As soon as your opponent plays a move, spend the first ten seconds looking only for the ideas behind that move. That way, your very first thought goes to your opponent's plan rather than your own.

Ramesh doesn't stop there. He suggests spending the next ten seconds hunting for the downside of that same move, the drawbacks that come with it. Every move gains your opponent something and gives something up at the same time. New squares come under control, but others get left behind. Those abandoned squares are exactly what Ramesh wants you to notice.

Finally, he asks you to spend a last ten seconds looking for three replies to your opponent's move: two quiet ones and one tactical shot. If your opponent is attacking one of your pieces, for example, find two ways to defend it and one way to counterattack. It forces you to stay imaginative.

Once those first thirty seconds are behind you, you're ready to analyze the position on its own terms, this time with your opponent's ideas already factored in.

Before we get to our conference, it's worth knowing that Anatoly Karpov and Aron Nimzowitsch are both regarded as masters of prophylaxis. Study their games and you'll start spotting prophylactic ideas everywhere.

A Conference on Prophylaxis in Chess

French youth national team coach and grandmaster Anthony Wirig recorded a conference covering three ideas, the basic two-rook checkmate, prophylaxis in action, and a harmonious development plan for White against the Pirc Defense. The English version isn't ready yet. Join the waitlist and we'll send it to you when it's out.

Your Move

Prophylaxis is one of the trickiest habits to build at the board, but it pays off the moment you stop reacting and start anticipating your opponent's next idea.
