Let's Check, shall we?
"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.
The algorithm of retrograde analysis was proved correct as far back as 1912, but only became practical with the advent of powerful computers. 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.
At the airport, in the hotel or at home on your couch: with the new ChessBase you always have access to the whole ChessBase world: the new ChessBase video library, tactics server, opening training App, the live database with eight million games, Let’s Check and web access to playchess.com 62.Rc8!

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!
Significance of the tablebases (2018)
GM Karsten Mueller explains the significance of endgame tablebases in conjunction with the launch of Endgame Turbo 5.
Perfect endgame analysis and a huge increase in engine performance: Get it with the new Endgame Turbo 5! This brings the full 6-piece Syzygy endgame tablebases on a pendrive. Just plug it in a USB socket and you are set!
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.
