  Ed Schröder, pioneer of chess engine programming, has in his retirement turned his attention to a new and very exciting project: to extract games from a database collection that are especially aggressive – that are short and have daring sacrifices and king attacks. He shows us the kinds of result you can get. Best of all: you can download the utility and use it on your databases.

• Rebel and playing style in chess

  Ed Schröder is a pioneer in chess programming. In the 1990s his program Rebel won a number of World Championships in computer chess, and always had a special place in the community, due to its playing style. In 2003 he retired from competitive computer chess, only releasing freeware versions of Rebel. Now Ed has come out of retirement and is undertaking some interesting new projects – like extracting the most interesting games from historical databases. And he is sharing them with us.

• Ivan Sokolov: Understanding Middlegame Strategy Vol 12: Reversed Colour Systems – King’s Indian/Pirc Defence

  Ivan Sokolov’s new course examines colour-reversed King’s Indian and Pirc structures, showing how extra tempi influence typical plans and why these positions feel uncomfortable for humans but not for engines. He analyses key model games from Kramnik, Botvinnik, and Fischer, demonstrating that White usually gets a pleasant setup without a guaranteed advantage, leading to sharp, dynamic battles decided by understanding rather than theory. The course equips practical players, both with white and black, with clear ideas, typical patterns, and concrete plans for navigating these complex reversed-colour systems.
