Thirty years! Happy Birthday Fritz (1)

by Frederic Friedel
11/5/2021 – In November 1991 ChessBase launched its first chess playing program for PCs. It was a modest start, but one that went on to completely change the chess world. Today, we start retracing the steps that led to the development of a fledgling chess program that went on to become one of the most powerful entities that has ever played the game – one that top players consult when preparing for their next tournament or match.

Everyone uses ChessBase, from the World Champion to the amateur next door. It is the program of choice for anyone who loves the game and wants to know more about it. Start your personal success story with ChessBase and enjoy the game even more.


It was 1991. For five years ChessBase had been vigorously selling its professional database program, which most ambitious chess players, all the way up to the World Champion, were using to study the game. It could show you the latest opening trends, their success in present-day tournaments, or the performance of your opponents in these openings. It could give you  examples of important endings, and show you how very strong players handled them.

What the database program couldn't do was to play a game against you, or advise you on the quality of individual moves. Why not, our company thought. A plan was born!

Frans Morsch, born in 1954, was a Dutch physicist who had started experimenting with chess programs when he was thirteen. He had become a professional computer chess programmer and supplied the companies Hegener & Glaser, Saitek, and TASC with his program Quest for their dedicated chess computers.

In early 1991 we contacted Frans. In a long walk in a park in Bonn ChessBase founders Matthias Wüllenweber and Frederic Friedel convinced him to write an MS/DOS version of Quest, which could be used as a playing program on a PC.

In a few months Frans delivered the PC version of Quest, and ChessBase got to work designing its first chess playing program – in the style of its database program. It had its own Graphical User Interface (until version 4, released in 1996, which ran on Windows). Quest was the main engine used in Fritz 1 to 13. 

One of the problems was finding a name for this program. "Grandmaster Chess", "Chess Complete", "Total Chess"? We consulted one of German's leading marketing and branding experts, Olaf Oldigs, who came up with a startling idea: Call it "Fritz," give it a personal, non-threatening name. Germany had just been reunited and for the first time in decades we were feeling good about being German. "Fritz" is the slightly derogative nickname the British had given us (they were "Tommies"), so let's go with  that...

I should mention that our US representative was not comfortable with the decision, and renamed the program "Knightsalker" for the American market. You may want to google "Night Stalker" to find out why this was not a good idea. A year later it was Fritz in the US as well.

So Fritz it became, and it turned out to be a very fortunate decision. It was pleasant for people to say "I played this wonderful game against Fritz," or "Fritz wants to simply take the pawn in this position," or "I have to show this to Fritz!" Anand once said (about a later version): "Fritz has become one of us. He is like a well-respected grandmaster who trains and advises us. The only difference is he doesn't come to the bar in the evening to share a beer."

Initially Fritz was a cute little toy. At least that was how top players who visited me in my home considered it. And I watched their view change over the years. As we brought out new versions they went from "It's fun, but not serious," to "well, it is getting pretty good," to locking themselves up alone in my study, so as not to be distracted while playing Fritz.

Fritz has had a long and exciting career. We will be telling you more about it soon...

My first Fritz-version was Fritz2 (still great fun to return to it), but via a beta tester I also had a copy of Quest (amazing little DOS program). Been a fan all those years, from F2 over F3, F5.32, F6, F8, DF12 & 13 to FF2. And yes please, could the old engines be converted to uci engines?

Deep Fritz 10.1 was the highlight

The others after it weren’t the same

I agree, please provide a large gallery of screenshots and covers of all your programs going back to the beginning.

When is Fritz 18 coming out? I'm seeing adverts from other retailers trailblazing it...

Fritz 5.32 is free and runs on relatively recent interfaces such as that of DeepFritz 12.
It confronted J. Polgar in a 1999 rapid match that it won 5.5 to 2.5.
You can use it to confront her, stockfish can't do that ...
I would like a record that everyone is on, so this is Polgar, this is Kasparov, etc ...
And Fritz's early engines are not translated as uci.

my first version of it was Fritz 5.32, good old days!

I'm looking for the Deeep Fritz 10 which is the one from the match with Kramnik but I can't find it.
Why not reissue all of these engines confronting famous players?
