What's new in Fritz 17

How do you improve and build upon the world’s longest lasting chess playing program series? If you have followed the news pages for the last weeks, you will have heard of Fat Fritz as a concept, and while it is indeed the show-stopping addition to Fritz 17, it is far from the only novelty. For one thing, a brand new Fritz 17 engine is now in place with no need for a fancy graphics card to reap the benefits. Developed by Frank Schneider, the author of a very strong private engine known as Gingko, the new Fritz 17 engine will not only surpass the previous Fritz 16, but also provide new analysis for those seeking yet another new look at things.

As far as the interface is concerned, the key concept is 'helping you learn'. A number of brand new functions have been created with the sole purpose of helping you learn and train your openings. Let's face it, while studying openings can be fun, memorizing them is not and is often the reason many players avoid openings they might prefer, because of the challenge that presents. Fritz 17 brings an assortment of tools to help you and make that process as painless as possible.

Finally, Fritz 17 and ChessBase will not be left behind in the wave of new 3D technology. Readers may have heard about the concept of Ray Tracing, the new buzzword by Nvidia on fantastic lighting in 3D models, even used to debunk moon landing conspiracy theories by demonstrating the accuracy of all lighting effects. Their new series of video cards was designed around this concept, and new games and 3D modeling have exploded with the steady inclusion of it. New in Fritz 17 is a powerful set of live ray tracing effects for the 3D chess boards, with a staggering amount of control on how and where they are lit. Even fancy camera effects such as background blurring are possible. However, these do require those fancy new video cards to be enabled.

In any previous version of Fritz, all the above would more than justify a new version and release, but the icing on the cake is of course Fat Fritz.

Fat Fritz

The pièce de résistance in Fritz 17 for many people will be the inclusion of Fat Fritz. Based on the AI technology by DeepMind that created AlphaZero, Fat Fritz is a new set of custom made neural network weights that work in the open-source project Leela Chess Zero. The Leela Chess Zero project is based on the Go program Leela Zero and was designed to reproduce AlphaZero on the PC. One of the key tenets is that it follows the ‘zero’ philosophy which means it uses nothing except what it learns of its own accord. 

The philosophy behind Fat Fritz has been to make it the strongest and most versatile neural network by including material from all sources with no such 'zero' restrictions, such as millions of the best games in history played by humans, games by the best engines including Stockfish, Rybka, Houdini, and more, endgame tablebases, openings, and so on. If it was deemed a possible source of improvement, ‘zero’ or not, it was used. Even millions of exclusive self-play games were created, but tweaked to create content that was more aggressive and speculative to learn from and mold its style. The only material that was not used to train Fat Fritz, out of principle, was content from the Leela project itself, as this was developed by their community for their neural networks.

After over a year of development, thousands of hours of computer time and human effort, we feel this will enrich analysts and players with creative and unique moves, all of the highest quality, to explore openings and the middlegame. While there is no question that making sure the engine can bring the highest standard is vital, and worry not it is there, it would be quite uninteresting to present an analyst that was essentially exactly the same as Engine X, except 20 Elo better. Instead, a contrasting point of view, no less strong, is far more interesting, and of far greater use.

Over the past weeks, many games, matches, and articles we have waxed poetic on its virtues, but instead of just throwing more mind-numbing results — however good — the following game speaks far louder than words on what sort of player it is.

This was a draw (yes, a draw, but what a draw!) between Leela and Fat Fritz in a game played without a book by Fat Fritz. It played the French defense, and took a line that is considered by theory to be quite bad for Black, and saved it with novel moves, and then gave up pawn after pawn to fight with dynamic play.

Important note: While Fat Fritz is already incredibly strong, its development is not over, and over the next months, owners of Fritz 17 will enjoy upgrades to the neural network.


Leela

Many fans of Leela have complained about the complications in the installation process and requested a solution by ChessBase. As such Leela will also come installed with its best neural network (and you can always use another of course) and configured for use on the spot. Hopefully this will help bring more users and admirers to their project as a result.

The Graphics Card question

Readers will have seen that to use Fat Fritz and Leela properly you will need a solid graphics card. There really is no way to get around this. The neural network weights are a massive file with tens of millions of values that comprise its vast knowledge of the game, and while the calculations are all done on the CPU, the graphics card, thanks to its unique design, is used to read the neural network and feed the CPU the evaluation for every position it examines. Even though Fat Fritz might be running a thousand times slower than conventional engines, it will still provide top analysis, but without a graphics card the experience will be only useful as a demonstration, and will be slower by a factor of 1000-2000.

If you wanted an excuse to get a fancy new graphics card, you can now tell your better half, "but honey, it's for chess!" Photo: Zotac

The recommended hardware is an Nvidia RTX 2060 or faster, but the better the card, the better the experience. Needless to say, a graphics card will also bring far more advantages than just running Fat Fritz, such as gaming, 3D graphics, video rendering, AI development, and more. On the upside, nearly any computer can use this and there is no need to buy an entirely new machine. The Fat Fritz in the Engine Cloud runs on a quite modest quad-core CPU (five years old), though bolstered by two fast RTX 2080 video cards.

True percentile output

win percentage output

One of the characteristics of the neural networks is that they learn and evaluate a position based on winning chances. Fat Fritz will break this down into not only the overall winning chances, but the expected wins, draws and losses. This is useful since saying a position has a 50% chance won't tell you if that means it expects 50% wins and 50% losses, or just 100% draws. Fritz 17 has been modified to allow users to see this pure output of the neural network.

Engine output

There is a new engine output option “Display win probabilities” that is active by default.

When you run the engine you will also see the breakdown at the bottom. You can see the first is the overall win rate, followed by the details of the wins, draws and losses.


Learn Chess Openings with Fritz 17

In Fritz 17 you will find several new opening management and training functions:

Manage your openings with "My Moves"

The new opening repertoire in Fritz 17 is called "My Moves". It is separate for White and Black. You add variations to your repertoire by clicking on a move anywhere in the program and marking it as "My Move". This will include the whole variation up to this move into your repertoire. Marking moves is the only way to store variations, but this also saves a lot of time from entering moves one by one, copying from a source.

Manage and drill your opening repertoire

Your "My Moves" repertoire is stored online. You can access it from any machine, and also from a web browser. But the goodies don't stop there. Imagine you are watching a live game in Playchess, whether a casual blitz, or a broadcast from a top GM tournament. Even then you can instantly check to see if a game played is following an opening from your repertoire.

 

In the LiveBook in Fritz (and via the web app as in the image below) the moves will be color coded, and you can see if the move is in your repertoire already. If it isn't, just click on it to add it.

My moves

Blue = This move is in your repertoire for White.
Green = Move is in your repertoire for Black.
Cyan = You play this move with both colors.
* (an asterisk) = Marked as 'My Move'.
** (to asterisks) = Marked as 'Important for me'.

Memorizing Opening Variations

Chess database software creates a seductive illusion. The well structured management of opening variations in your personal analysis creates the impression that one can reproduce them easily over the board. Of course pure opening research is fun. However for practical success you really have to be able to recall everything from memory. Fritz 17 introduces the Drill as an efficient and entertaining way to help with this.

Drill

When Drilling, you play your lines and Fritz answers in a way that you stay within your prepared repertoires. Moves are played according to their frequency in master games.

After some time, Fritz 17 detects which variations you know well and which you don’t. Then the shakier systems are offered more frequently so that you can solidify your memory in an efficient way. 

The drill dialog displays your ‘Memory Score’ If you reproduce the correct move for a position five times in a row, this position is counted as fully learned and scores one point. You have learned your repertoire 100% if you achieve this for any position.

Standard Repertoires

Fritz 17 provides access to standard opening repertoires for nearly every prominent line in chess. Those repertoires are regularly updated to current theory and recent games on our server. You can either drill them with Free Drill or upload them to ‘My Moves’. Or you pick single lines by marking moves. Of course you may simply store them in your traditional databases. Open a list by calling Openings → Standard Repertoires. Click on any entry and it will automatically load.

Standard Repertoires are available in four levels: Easy ClubTournament and Professional. This saves work: As a normal club player you don’t have to extract the best moves from a deeply nested professional repertoire suitable only for master level players.

Opening Theory 'Laid Back'

The best way to memorize opening variations is to execute moves physically. On the screen or even better on a board. Your brain will be more engaged in what you do. However, sometimes at the end of a long day you just might want to lean back, relax and leave mouse and keyboard untouched.

To satisfy this, Fritz 17 introduces the replay of variation trees. You can watch your repertoire being played out on the screen. Lines are picked randomly and repeated as often as you like. Just let it run, set the speed and watch.

Opening features

Standard Repertoires and Full Tree Replay

Blitz & Train on Playchess.com

Still, learning is not just memorization, and improving upon one's games is a key part of it all. Here too new functions will now go through your games, or games of your choice, to highlight mistakes, combinations, or sacrifices, and present them as ready-made exercises you can solve on your computer, or print out for yourself or your students.

You can print out the puzzles just like a book, with diagrams first and the solutions at the end.

Blitz games contain tactical errors. Errors usually happen at interesting positions, so you can learn from them. Since the last version of Fritz, games played on Playchess.com are analysed automatically, but that brought a dilemma:

Blitz & Train

Should one look at the analysis or play the next game?

The new function “Blitz & Train” helps with this: It creates training material from your online games, no matter whether they have been played today or last month. A few clicks and you can print exercise sheets from your own games. Click the tab 'Training' in the Playchess section of Fritz:

The option Sacrifices finds exercises with beautiful moves, while Blunders asks for the best move in position where one side blundered.

3D boards with Ray Tracing

With the arrival of the newest generation of video cards from Nvidia, Ray Tracing has now become a reality in real time. In a nutshell the idea is that it is able to calculate and show light reflections from surface to surface in all of the incredibly complex relationships such as sunlight bouncing off a wall, which gives a lighter light, filtered through humid air, and so on. ChessBase has now introduced this added layer of realism to its 3D boards, with full control over every aspect if such is your desire.

The menu will now offer the option between the CPU built ray traced boards and the new GPU acceleration.

The options are enormous and even include fancy optical effects such as background blurring.

Needless to say, if you do not have a graphics card that can handle this, or do not want it, the classic 3D boards are still there for your enjoyment.

We hope you enjoy Fritz 17!

Fritz 17 represents one of the most ambitious and progressive versions ever, bringing to you tools that should help all players contend with modern problems. From the challenges of memorizing and studying complex opening theory, to easily reviewing games with a focus on improving your practical skills, to bringing what is bound to be an amazing addition to your arsenal of tools: Fat Fritz. In fact, Fritz 17 brings not one engine, but four: a brand new Fritz 17 engine, the new custom made neural network Fat Fritz with its penchant towards cutthroat chess, the well-established Leela with its very Karpovian approach to chess in a no-headache installation, and Stockfish itself. Plus a surprise in the near future!

douglas_stewart douglas_stewart 11/29/2019 01:44
When you run Full Analysis on a game, what do these numbers mean? I assume conceptually it measures the accuracy of each players' moves, but what do the numbers mean specifically? I'm guessing it's something like the number of moves that were close to best, the number a little further away, and the total number of moves considered. I haven't been able to guess a way to reproduce the calculated percentage.

Accuracy: White = 35% (6/5/19), Black = 69% (12/6/21).
pcst pcst 11/17/2019 07:06
I mean it think likes robot but it not understand rule if you write the rule and include to every files of that program refer to calculate it will strong more and hard to beat. If it understand the rules. It will incredible and cleaved smart thinking.
pcst pcst 11/17/2019 06:43
Every program of chess it strong now but endgame it nice like a robot if the program no the rules more than this a bit it will strong much more now. I mean in yours source code must include traded file that you writing in program to files that links to calculation it will zigzag automatic and much more strong engines if you try like I explain you will see the results of cleaved program and hardware work good process. ENJOY.
foobarred foobarred 11/16/2019 10:56
in Fritz 16, you cannot pause or adjourn a friendly or rated game. Ive been told that Fritz 17 does not have that capability either.

Part of the reason to play against the PC is the convenience. Its mind boggling to me that this feature is nowhere to be found.

I would buy immediately if Fritz 17 had this.

In addition, it would be great if you could set up various profiles without needing a separate playchess account. For example, a regular account vs a blindfold account.
shahrad shahrad 11/15/2019 11:34
The standard repertoire for professional is actually a club level repertoire.
MJXII MJXII 11/15/2019 07:42
I really like the integration of LC0 and the other new features look interesting as well. But it's always hard to read an article and really get a feel for what the program and features are like to use in practice. I'd love to see some videos showing the new features, so I can more easily imagine if it's something I'd enjoy using myself.
chessmatt chessmatt 11/14/2019 08:01
As a follow up suggestion for future - please consider adding a new evaluation profile chart for Fat Fritz/LC0 that plots four lines for overall, win, draw, and loss probabilities. I think that would be very interesting to see if the game shifts for example from "even" winning chances to high draw odds, where that shift happens, and why.
chessmatt chessmatt 11/14/2019 07:52
I am really liking the implementation of Fat Fritz with the explicit probabilities (overall - win - draw - loss) for the evaluation. I am finding it very interesting - especially for candidates that have comparable traditional evaluations. Really helps to illustrate that not all equal positions are equal :P Is there a way to also output the probabilities rather than the pawn equivalent eval with the LC0 engine for comparison?

Also I noted that the setup for LC0 through Fritz 17 seems to have optimized for my graphic card better than my manual installation previously did. I have "-rtx" options for both Fat Fritz and LC0 that are providing significantly better kN/S performance than I was getting with my manual install. If we update our graphics driver is there a need to redo that optimization - and if so how do we re-run it?

Thanks!

Thank you @macauley. Black Friday and Cyber Monday are around the corner, so the timing of the follow-up article could not be better if one wishes to make some GPU purchases!
macauley macauley 11/13/2019 07:58
@EatMyShorts - We're going to have a follow-up article discussing this in more detail in the next day or so.
EatMyShorts EatMyShorts 11/13/2019 07:52
OK...so what constitutes a "BETTER" video NVIDIA card insofar as Fat Fritz is concerned? Is it higher memory clocks? Higher core clocks? More CUDA cores? Is it a combination of some or all of these attributes? Is there a formula that one could apply to determine which cards are best? AND, I take it that the more cards, the better - such that having 4 cards allow Fat Fritz to play stronger than it would if one used only 2 of the same cards...not necessarily a linear increase in playing strength, but an increase nonetheless?

@stolowski That's what I wanted to know. Thank you! What a pity - such a sophisticated program, and they didn't think of the basic things...
stolowski stolowski 11/12/2019 08:37
@Kiltak I haven't checked it, best if you look at the manual, it seems to have all analysis options covered: http://help.chessbase.com/Fritz/17/Eng/index.html?000001.htm

@Latus: fliping the board while setting the position is still not possible in Fritz 17, I also tried the common keyboard shortcut (CTRL+F) and it doesn't work in position setup window.
Gildor Gildor 11/12/2019 08:36
I have the same question as Metaphysician and jog: There are two setup programs, one fo Windows 10 and one for 64bit. Which one should one use for a Windows 10 64bit computer? Many thanks for any help with this!
Kiltak Kiltak 11/12/2019 08:31
@stolowski Did you try the game analysis modes? Does it have a deep analysis with iterations (like Chessbase 13~15)?
stolowski stolowski 11/12/2019 08:18
This looks like a nice upgrade and I got it on day 1, but as with every previous release in its early days, it has quite a few bugs around the new "My Moves" functionality. For example, when watching a fritztrainer video, switching to "My Moves" tab will append all the notation from the training video to "My Moves". Another problem I found is that "My Moves" tab contents doesn't get updated as I mark select moves in the notation tab - I need to click "Load white" every time to have "My moves" show latest moves as I work them out. Yet another: "Drill" functinality is only available when starting Fritz in "Easy game" mode from the startup screen for some reason.
In general I like the promises of Fritz 17 but having these fundamental bugs is a little annoying, I hope they can get patched quickly. In the meantime, extra care recommended with "My Moves" functionality before putting too much effort into creating a repertoire (and having it messed up).
Latus Latus 11/12/2019 08:03
@Kiltak Thank you for your help. I have not tried it so far. I have a Fritz 16, and when I go to ''easy game'' or ''enter and analyse'' and then ''position setup'' there is no flip board option - there is only observation option and game settings from a white perspective.. :/ :(
Kiltak Kiltak 11/12/2019 07:39
@Latus did you try the ribbon arrow (quick access bar)? It shows some options to add to ribbon and one of them is to flip the board.
I remember using that in previous versions of Fritz or do you mean something else?
Latus Latus 11/12/2019 07:32
All versions of Fritz so far have had one serious flaw in my opinion, which is that they did not allow the option ''flip the board'', at the position setting level. Is this now corrected with the Fritz 17 version? If so, I buy it right away...
Kiltak Kiltak 11/12/2019 05:04
How does Fritz game analysis works? Does it have Deep Analysis similar to Chessbase with timed iterations? Or uses the old depth/time?
Metaphysician Metaphysician 11/12/2019 04:38
@Bertman Thank you so much!
Could you please help with another question? The new Fritz comes with one setup program called Fritz17Setup_Win10 and another called Fritz17Setup_x64. Why two? What should I install if I have Win 10 64-bit?
Thanks.

@metaphysician - I will be posting an article to deal with such questions, but for now in the UCI options, change the backend to "Multiplexing", paste the following into the line that says Backend Options just below it: (backend=cudnn-fp16,gpu=0),(backend=cudnn-fp16,gpu=1) and in the threads change the number to 4.
