The central new function in ChessBase 16 consists of automatic opening surveys for any move whatsoever. Until now opening preparation was above all about move selection. With the traditional tools such as LiveBook, Reference and Online Database, however, one’s attention is strongly concentrated on only the next move. It is much more effective to have a variation tree, an opening survey. ChessBase now provides that. At a glance you will see the complete opening in front of your eyes and you can immediately evaluate which variations are important to master safely. This ready survey can perhaps be supplemented by material you have prepared yourself and thus quickly becomes part of your own repertoire. But how is the move selection made? That may happen through an algorithm, but it is you who set the parameters, the style of the opening choice. To set it there is the choice between Main Lines – Fashion – Side lines – Gambit – Attack – Positional and Endgame. I would like to briefly present some of the styles which are perhaps most important for your practice.
“Fashion”. In it moves are selected which dominate modern practice. This often results in considerable deviations from the traditional main variations and delivers the most interesting and theoretically best founded survey. For the time-poor practician we recommend the “Side lines” style. Just as on a Google search we usually click only on the top links, in opening preparation too those moves which are frequently played and at the top of the list exercise a magnetic attraction. Like this, very playable secondary systems are overlooked through which passable positions can be reached and which demand little preparation time. There is a somewhat flashy opening survey in “Gambit” style, which takes into account any half-way playable sacrifice. Almost every one of the known gambits in chess theory will certainly show up in these surveys. Then we also have the style “Attack”. It searches in respectable recent games for the sharpest continuations possible. That leads to very aggressive secondary systems, e.g. often with an early h2-h4. When you wonder: “Who plays something like that?”, the answer is quite often “Magnus Carlsen”.
The search is based on your own reference database, thus best of all the latest Mega Database including the online updates. If someone else with a reasonably up-to-date reference database has already looked at a survey from that particular move it (while adjustable) comes directly from the server and thus is ready immediately.
Opening surveys with deeply nested variations make particular demands on the representation of the notation. For that reason ChessBase 16 possesses a new way of “folding” variations which can be opened or closed simply with a click of the mouse. Another novelty is the automatic recognition of games quoted. All the opening surveys of ChessBase 16 contain pointers to recent strong sample games.
The tactical analysis for automatically commenting on games is extended by means of particular opening comments. ChessBase 16 recognises whether an innovation is important and comments appropriately. Furthermore, hints are provided to recent theoretical trends and successful secondary systems.

Fritz 17 - The giant PC chess program, now with Fat Fritz
At the turn of the century, Fritz fascinated the chess world with victories over Garry Kasparov and then-reigning World Champion Vladimir Kramnik. The "most popular chess program" (according to German magazine Der Spiegel) offers you everything you will need as a dedicated chess enthusiast, with innovative training methods for amateurs and professionals alike, plus access to the full suite of ChessBase web apps, including the Playchess playing server.
The neural chess engine "Fat Fritz"
In December 2017, a press release from Google shook the chess world to the core: its subsidiary Deep Mind built a neural network, dubbed Alpha Zero, which "learned" chess solely by playing millions of games against itself, yet was strong enough to beat Stockfish 8, a leading chess engine. This news was sobering and fascinating at the same time. Sobering in the sense that the decades old tradition of chess programming had been relegated to the shadows by a self-learning system. Fascinating because it was possible to hope that one could learn really new stuff about chess from this radical approach.
Nobody had expected that a cooperative effort by chess developers would soon make this technology generally available. The Open-Source- Project LCZero began to retrace the trail blazed by Google and in the meantime has acquired considerable strength. Suddenly a chess engine was available whose different analysis results provided new ideas on all fronts. LCZero too follows the Google philosophy, that the neural network only learns from games played against itself.
The idea soon came to use our existing base of hundreds of thousands of good grandmaster games to shorten this learning process. This approach was followed logically by our longserving technical editor Albert Silver and based on the LCZero technology he trained a neural network for a whole year with GM games.
The result is so convincing that we are now publishing it as “Fat Fritz” along with Fritz17. As things stand, Fat Fritz defeats in a direct comparison all traditional chess programs and even LCZero. The moves suggested in analysis are often extremely human and planned. With a painfully practical limitation: Fat Fritz needs (like LCZero) a very high performance Nvidia graphics card (“GPU”) in order to achieve its full playing strength. Nevertheless, here for the first time in many years we can record a real breakthrough in chess programming. Fat Fritz and LCZero are already beginning to change opening theory.
Methodical opening training
Every average human brain is light years ahead of neural networks when it comes to mastering everyday situations. However, it is in some ways tiresome imprinting on one’s own neural network knowledge about opening variations.
Therefore Fritz 17 has new functions to offer to considerably simplify the constructing, administration and above all the transfer to memory of an opening repertoire. What use is the finest variation tree if one can’t remember it? Fritz 17 introduces a repertoire administration which is not based on whole variations but on moves. You decide on a move: “at’s the one I want to play myself ” and thereupon the whole variation is taken over into your repertoire. The advantage: with some decisions and a few clicks you can set up a useable repertoire. This repertoire is online, i.e. it can be accessed immediately by any computer and on the web.
Drill and play
Once you have clicked together a repertoire in that way, the fun begins: you now learn it by drilling. To do so you play your variations and Fritz replies in such a way that, as far as possible, you remain within your repertoire. At first the moves come according to their frequency in theory. After some time it becomes clear what you have mastered properly and what not. The problematic systems are then repeated more often so that you can achieve certainty quickly with the minimum of effort. This system is known from the learning of foreign languages.
For it to be fun, Fritz measures the size of the theoretical area you have mastered and enters it into a ranking list as a number of points. Helpful for practice is also the fact that in your drilling when you reach the end of a variation you can decide if you want to carry on as a training game. Drilling can also be done with any variation tree you wish to load (traditional ChessBase repertoire), even with a sole game if you would like to learn it by heart.
Ready-made repertoires included
Included with Fritz 17 is access to pre-prepared up-to-date repertoires. You can either drill with these as they come or incorporate them into your own repertoire with the usual clicks to mark moves. These ready-made repertoires can be found in each case at four levels: simple, club, tournament and professional. at saves work; you do not need to extract a simpler club-level version from full-fledged professional repertoire on your own.
