EXPAND YOUR CHESS HORIZONS Data, plans, practice – the new Opening Report In ChessBase there are always attempts to show the typical plans of an opening variation. In the age of engines, chess is much more concrete than previously thought. But amateurs in particular love openings with clear plans, see the London System. In ChessBase ’26, three functions deal with the display of plans. The new opening report examines which piece moves or pawn advances are significant for each important variation. In the reference search you can now see on the board where the pieces usually go. If you start the new Monte Carlo analysis, the board also shows the most common figure paths.
Commentary by GM Leinier Perez Dominguez and GM Antoaneta Stefanova
Why memorising endless theory might not be the best path - and how an idea-based repertoire can change your game. In today’s fast-paced chess world, especially online, where blitz and rapid games dominate, the traditional approach of grinding through lines of opening theory can feel overwhelming, and even unnecessary. The real challenge? Striking the right balance in your opening preparation. How deep should you go? Where do you stop? This course is built on the timeless wisdom of my legendary coach, Chebanenko, who designed opening repertoires for his “lazy” students - not lazy in attitude, but smart in approach. His philosophy? Don’t memorise. Understand.
In this course, you’ll learn how to take the initiative against the London and prevent White from comfortably playing their usual system by playing 1.d4 Nf6 2.Bf4 Nh5.
London System Powerbase 2026 is a database and contains in all 11 285 games from Mega 2026 and the Correspondence Database 2026, of which 282 are annotated.
The London System Powerbook 2026 is based on more than 410 000 games or game fragments from different opening moves and ECO codes; what they all have in common is that White plays d4 and Bf4 but does not play c4.
In this course, Grandmaster Elisabeth Pähtz presents the London System, a structured and ambitious approach based on the immediate Bf4, leading to rich and dynamic positions.
Opening videos: Open Spanish (Sipke Ernst) and Classical Sicilian (Nico Zwirs). Endgame Special by Igor Stohl: ‘Short or long side’ – where should the defending king be placed in rook endgames? ‘Lucky bag’ with 35 master analyses.
YOUR EASY ACCESS TO OPENING THEORY: Whether you want to build up a reliable and powerful opening repertoire or find new opening ideas for your existing repertoire, the Opening Encyclopaedia covers the entire opening theory on one product.
The Queen’s Gambit Declined Exchange Variation with 5.Bf4 has a great balance between positional play and sharp pawn pushes; and will be a surprise for your opponents while being easy to learn for you, as the key patterns are familiar.
