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.
