"It's really fascinating what is possible nowadays thanks to the technological progress", Dr. Karsten Mueller recently opined.

ChessBase has recently incorporated a version of the 7-piece tablebases into the cloud-based Let's Check web app, part of the ChessBase account.

In the video below Mueller recounts how tablebases have improved and evolved over the past decade, and shows examples, which you can replay on your own in the game viewer below as well.

Endgame Turbo 5: 6-piece tablebase on a USB stick

The latest 7-piece tablebases are still too large to use at this point within ChessBase with a local engine, however you can have access to 6-piece tablebases wherever you are, even without and internet connection thanks to Endgame Turbo 5.

With the Endgame Turbo 5, engines play endgames with six pieces or fewer perfectly, but they also play endgames with more than six pieces much better because the Endgame Turbo lets them know which six-piece-endgames are won, drawn or lost. It helps you to improve your endgame play, and is a powerful tool for correspondence players, endgame theoreticians, friends of engine matches, and anyone interested in the endgame phase!

Rook endings are amongst the most frequently encountered endgames there are, and so your training effort will be quickly repaid in the form of half and full points. Knowing even a few rules of thumb and key methods makes life a great deal easier and provides a guiding light even in complex positions. This DVD focuses on the important themes which are to be found in common rook endings.


Karsten Müller is considered to be one of the greatest endgame experts in the world. His books on the endgame - among them "Fundamentals of Chess Endings", co-authored with Frank Lamprecht, that helped to improve Magnus Carlsen's endgame knowledge - and his endgame columns for the ChessCafe website and the ChessBase Magazine helped to establish and to confirm this reputation. Karsten's Fritztrainer DVDs on the endgame are bestsellers. The mathematician with a PhD lives in Hamburg, and for more than 25 years he has been scoring points for the Hamburger Schachklub (HSK) in the Bundesliga.
