103 London System Repertoire: 1.d4 d5 Variations

We continue our series of the London System repertoire for Main Line Monday. This we look at the various odd lines after 1.d4 d5. More popular lines will be considered next week. Below are some typical variations that I prepared for a recent tournament.

For much of my London System theory, I rely on the book "Win with the London System" by Sverre Johnsen and GM Vlatko Kovacevic. This grandmaster has played this opening throughout his career. One thing I learned from his book is the value of playing c4 as White instead of the more traditional c3 in some lines. This is especially true when Black has played an early ...Bf5.
