How to Excel at Prophylaxis

Today’s post is devoted to prophylaxis in chess! Every now and then, we ordinary players, face positions in which we need to prevent the opponent’s threats and do that effectively. In that kind of positions, no counter attack or active play would get us out of trouble and that’s why it’s so important to know the principles of prophylaxis in chess. In this lecture, I am talking about the secrets of successful prophylaxis and by secrets I mean all of these relevant techniques that may sound ineffective and counter-intuitive to the average player. Here, I am trying to explain why the small, quiet moves may sometimes be very useful and how we can find the most precise moves to defend our opponent’s threats successfully. For this lecture, I have selected a very instructive example, a game by the great positional player, Anatoly Karpov, who managed to defend and exploit his opponent’s desire to attack when all his attacking chances were suddenly eliminated. Enjoy!

    thank you, clear, succinct.  Often when I follow advanced games I am left baffled by some apparently passive or inconsequential moves, this will help me a lot to understand some of these.

    That was very good, thank you.  This is exactly what I've gotten away from that I used to do regularly.  Good pace to the analysis, and it was clear what you were teaching.  Thank you again!

    Thanks for this lecture, very well explained. Prophylaxis kinda baffled me since I couldn't grasp the idea because I always think that inactivity or what looks like inactivity to a begineer is not good in chess ever. But after this explanation and that amazing game by Karpov in which he exploited the idea perfectly is like I have new eyes lol thx and I look forward to applying this idea to my games.

    This is an outstanding educational video; the hobby tournament player with a penchant for fundamental play (rather than hours upon hours of study to acquire theoretical dominance) or the active Scholastic rising star will gain leaps and bounds from this academic strategy. I will certainly keep an eye out for more IM Lilov!
