Typical Tactic Ideas in The London System – IM Eric Rosen

The London System – IM Eric Rosen [80/20 Tactics]

If you want to really know an opening, you should be familiar with its typical positional ideas and remember the most important theoretical lines. But this is not enough.

Each opening has its own unique tactical patterns. Patterns you need to know to succeed.

IM Eric Rosen’s course on the essential tactics in the London System gives you a complete understanding of the typical patterns for both sides.

Even if you only play against the London System, knowledge of these resources will prove invaluable.

The London System is a flexible opening which White can use virtually against any of Black’s setups. This makes it the perfect choice for players who prefer to understand key strategic and tactical ideas instead of having to memorize an endless number of theoretical variations.

The aim of this DVD is to give you a high-level understanding of the typical themes of the London System, and really cement this knowledge in your long-term memory with the included practical tests.

About the Author:

Eric Rosen is an International Master born in the USA.

The London System – Im Eric Rosen [80/20 Tactics]

IM Eric Rosen

Rosen showed interest in the game from a very young age. He learned the rules of the game at age 7 and competed in his first tournament at age 8. By age 9, he won the IL 3rd Grade State Championship.

During the early years of Rosen’s chess career, he studied with Tamara Golovey, a professional chess coach originally from Belarus now living in the Chicago area.

Golovey was a former coach of GM Yury Shulman and World Championship contender GM Boris Gelfand. She provided Rosen with a strong foundational understanding of the game.

Rosen became a National Master in 2009, a FIDE Master in 2011, and an International Master in 2015.

The London System (Main Moves)

The most common move order in which the London System chess opening arises on the board is 1.d4 Nf6 2.Bf4.

The London System Opening – Main Variation

In this case, Black has responded to White’s first move 1.d4 with one of the most popular moves, which could lead to very complicated opening positions such as the King’s Indian Defense, Queen’s Indian Defense, Benko Gambit, Budapest Gambit, etc, but White’s second move 2.Bf4 immediately sets the stage for the London System instead.

Another common move order in which White could choose to develop the London System opening is 1.d4 d5 2.Nf3 Nf6 3.Bf4.

The London System Opening against 2… d5

This time, Black has responded to White’s first move with …d5, which can lead to some of the main lines of the Queen’s Gambit such as The Slav Defense, The Albin Counter-gambit, etc.

But White’s second and third moves avoid any of those well-known theoretical lines and sets the stage for The London System.

This flexible chess opening is a weapon that you can use against virtually any Black defense and thus comprises a smaller body of opening theory than many other openings.

Is this course for me?

The 80/20 series helps you get the most from your study time by combining learning openings with training tactics.

If you’d like to learn all the typical tactical ideas that can arise from the London System, then IM Eric Rosen has got you covered.

This course is designed to give you the best return on your training time by hitting 3 areas at once:

  • Mastering The London System by observing games from some of the strongest players in the world.
  • Understanding Tactical patterns.
  • Calculation.

Analysing games from Magnus Carlsen, Alexander Grischuk, and Hikaru Nakamura will help you dominate all the concepts and possibilities of the system by just observing how the strongest players execute.

Patterns alert you to possibilities, calculation makes them a reality. Rosen will show you how to make analysis easy with techniques like “reversing the move order”, “doing it anyway” and “weak point overload”.

Enjoy this awesome lesson with the young expert Eric Rosen!

  1. Rated 5 out of 5


    As a beginning chess player, I’ve grown to like the london system because I don’t have to memorize lots of theoretical variations. This course really taught me the tactics that lurk into the position and allowed me to get an edge early on. I learned how to approach different defenses against the london. For example, I used to play passively against the King’s Indian Defense, but now I know how to create an ideal set up and attack from the start. This course is perfect for any beginners like me who want to have a better understanding of the london system.

    I purchased this to compliment, Damian Lemos Deep Dive London System material and have used this content to sharpen my knowledge of the London System and to train myself in pattern recognition to spot when a tactic is available in the opening. It also provides more detail and a deeper look into how to exploit some of the typical mistakes black can make when you are opening with the London System. The package offers mininature lessons as well video quizzes to reference what you have learned. Eric Rosen allow addresses which moves were suggested by computer analysis versus moves readily identifable over the Board so there is probably some novelty in these tactics that hasn’t been widely disseminated in learning instruction. His teaching style is staight forward, simple, and understandable. Very worthwhile purchase.

    I’ve got back into chess recently after a very long break and I wanted to learn an opening for white that would give me a fighting chance in a beginner-intermediate game without learning vast amounts of theory. Eric Rosen’s excellent youtube talks on the London System, with its standard pattern of development, convinced me that a full training programme from Eric on the London was a good way to go. So far, I’m very pleased. You get a LOT of videos, documents, problems and tactical challenges for the money, probably enough to take me up to 1800 ELO (if I ever get that far!) and even though I’m only 25% of the way through it, it’s already helping my game. I definitely think it’s well worth the money.

    I’ve studied London system from various sources, not to discredit those but this is the best! Simply because there are so many tactical themes that I have overlooked in my tournament games. Rate this 10/10 and recommend for any serious tournament player

    This is an excellent tutorial on the London. IM Rosen does a great job of breaking it down and showing tactics that can show up in a London game. I like how he will ask what the next move should be, allowing us to find the tactic. This pushes us to learn more in the lesson, rather than just be a lecture.

    Great content for an amazing price. The videos covering the instructive games are interesting and to the point, but thoroughly cover the opening ideas and theory. The tactics videos are all very detailed and cover some interesting lines, including novelties. I was already fairly booked up and knowledgeable with the London system before I made this purchased and still found many things that made it a great buy. A few of the tactics are definite monster shots that can and will definitely show up in some games.
