Now with “Fat Fritz“ * : An extremely strong neural net engine inspired by Alpha Zero, which produces human-like strategic analyses of world class quality. at saves work you do not need to extract a simpler club-level version from full-fledged professional repertoire on your own. ese ready-made repertoires can be found in each case at four levels: simple, club, tournament and professional. You can either drill with these as they come or incorporate them into your own repertoire with the usual clicks to mark moves. Included with Fritz 17 is access to pre-prepared up-to-date repertoires. 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. 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. This system is known from the learning of foreign languages.įor 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. The problematic systems are then repeated more often so that you can achieve certainty quickly with the minimum of effort. After some time it becomes clear what you have mastered properly and what not. At first the moves come according to their frequency in theory. To do so you play your variations and Fritz replies in such a way that, as far as possible, you remain within your repertoire. Once you have clicked together a repertoire in that way, the fun begins: you now learn it by drilling. it can be accessed immediately by any computer and on the web. The advantage: with some decisions and a few clicks you can set up a useable repertoire.

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. 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. 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. However, it is in some ways tiresome imprinting on one’s own neural network knowledge about opening variations. Fat Fritz and LCZero are already beginning to change opening theory.Įvery average human brain is light years ahead of neural networks when it comes to mastering everyday situations.

Nevertheless, here for the rst time in many years we can record a real breakthrough in chess programming. 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. The moves suggested in analysis are often extremely human and planned. As things stand, Fat Fritz defeats in a direct comparison all traditional chess programs and even LCZero. The result is so convincing that we are now publishing it as “Fat Fritz” along with Fritz17. 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 idea soon came to use our existing base of hundreds of thousands of good grandmaster games to shorten this learning process. LCZero too follows the Google philosophy, that the neural network only learns from games played against itself. Suddenly a chess engine was available whose different analysis results provided new ideas on all fronts. The Open-Source- Project LCZero began to retrace the trail blazed by Google and in the meantime has acquired considerable strength. Nobody had expected that a cooperative effort by chess developers would soon make this technology generally available. Fascinating because it was possible to hope that one could learn really new stuff about chess from this radical approach. Sobering in the sense that the decades old tradition of chess programming had been relegated to the shadows by a self-learning system. This news was sobering and fascinating at the same time. 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. 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.

At the turn of the century, Fritz fascinated the chess world with victories over Garry Kasparov and then-reigning World Champion Vladimir Kramnik.
