The Modernized London System

Although the London System has been known for a long time, it has only surged in popularity in the last decade or so. This rise can likely be attributed to many players’ desire to focus more on the practical aspects of chess, emphasizing positional understanding over the heavy use of engines and memorization of long theoretical lines. The London System has seen not just an increase in the number of games but also a deeper understanding of the positions it produces. Historically, it was sporadically used, with only a few regular practitioners, such as grandmasters Milorad Knezevic and Vlado Kovacevic from the former Yugoslavia, and the English GM Tony Miles.

Today, players like Gata Kamsky and Magnus Carlsen frequently employ the London System, and it has become a staple in the repertoires of many other grandmasters and non-grandmasters alike. The system’s various move orders and the resulting transpositions make it unique, adding a layer of complexity not as prevalent in other openings.

My personal experience with the London System has been mixed. After losing a game to Grandmaster Volkov in the Rilton Cup, I initially decided that the resulting positions were not to my liking. However, in 2019, I revisited the London System during a game in a World Senior tournament and played exceptionally well. Like any opening, it can lead to both good and bad games, but the London System has undeniably become a significant part of 1.d4 theory.
