I am very excited to introduce my seminal work- "Transforming Pawn Structures" Database. Only recently I came to realization that this is the most important positional/strategical theme of chess game! First part of my Database features 27 instructive examples from "Prague Masters" Super Tournament. Out of 45 games played in the tournament 27 featured at least one, mostly several mistakes related to this topic, which makes 60% of the games? Can you imagine what is happening on lower levels? The second part is 10 deeply annotated games with fascinating pawn structure battles. On my site you will find a shorter (and cheaper) version of my publication on Modern-Chess platform. The full version also includes 10 hours of video, as well as 212 test positions extracted from these games. If you want to improve your positional-strategical game, I would highly recommend studying this material!
