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.
