[what is this?]

Fritz is a German chess program developed by Frans Morsch and Matthias Feist. It is one of the strongest commercially available chess programs.

The latest version of the consumer product is Fritz 10, but previous versions such as Fritz 3 were running as early as 1995. In 2002, a version of Fritz specifically designed for multi-processing, Deep Fritz (Computer), tied Vladimir Kramnik in Bahrain, with a match score of 4-4. In November 2003, X3D Fritz (Computer), a version of the program with a 3D interface, drew a four-game match against Garry Kasparov. In November of 2006, Fritz defeated Kramnik 4-2 in a rematch.

Pocket Fritz (Computer) is a version that is compatible for mobile device play. In 2000, it won the World Computer Speed Chess Championship.

Sep-04-09  Open Defence: Fritz 12 may be out by Oct....
Sep-04-09  timhortons: <Open Defence>

is there a fritz 12 for single processor?

my computer is a year old but only single processor.

Sep-04-09  Open Defence: <timhortons> Fritz is for single processors, Deep Fritz is for Multiple Processors, I have found Fruit 2.3.1 and Stockfish 1.4JA to be really good on single CPU machines

  Pyke: This might slightly be off-topic, but I have to get it out somewhere:

I am REALLY MAD at chessbase. They have this new policy that you have to pay 50 ducats (5 euros) for lectures, ChessbaseTv, and other stuff.

These programs used to be for free, when you got a normal account to play on their server.

Of course, when you buy the new Fritz 12 you get the premium membership and the programs are for free again.

In my opinion this is a ridiculous and shameless, unethical attempt to sell their rubbish product.

Chargeing 5 euros for one hour of commentary is RIDICULOUS !!!

Even the people that bought Fritz 11 quite recently and were promised to get full access to the page, have to pay the 5 euros or buy the new version of Fritz. Which is scandalous to say the least!

For me it's the last time I renewed my membership there (thank got it runs out in november) or bought any of their products.

Oct-23-09  whatthefat: <Pyke: Even the people that bought Fritz 11 quite recently and were promised to get full access to the page, have to pay the 5 euros or buy the new version of Fritz. Which is scandalous to say the least!>

That is ridiculous.

Feb-04-10  50 Moves ahead: <I got this antique Fritz 5.32 recently.Fritz experts out there will this old version from 1998 run on Windows Vista and how can I choose the colors to play in rated games?>
Mar-29-10  Everett: Apparently there was a speed mini-match between Kasparov and Fritz5.32 back in '99. I have the score of one game, from an old newspaper clipping by Soltis.

Czech Defense: Hannover 1999
White: Fritz5.32
Black: Kasparov, G.

1.e4 d6 2.d4 c6 3.Nf3 Bg4 4.h3 Bh5 5.Be3 e6 6.Nbd2 d5 7.e5 Nd7 8.Bd3 Ne7 9.0-0 Bg6 10.Be2 Nf5 11.c3 Be7 12.Qb3 b5 13.a4 Nxe3 14.fxe3 a6 15.Ra2 Nb6 16.axb5 axb5 17.Rfa1 Rxa2 18.Rxa2 0-0 19.Ra7 Bg5 20.Nf1 Bh6 21.Ra6 Be4 22.Qb4 Bxf3 23.Bxf3 Nc4 24.Kf2 Qg5 25.Rxc6 Nxe3 26.Qxb5 Nxf1 27.Kxf1 Qc1+ 28.Ke2 Bf4 29.Rb6 Qe3+ 30.Kf1 Qc1+ 31.Ke2 Qe3+ 32.Kf1 Qc1+ 33.Ke2 1/2

Soltis gives exlams for white's 29th and black's 12th and 21st. He gives a question mark to white's 7th and black's 28th, claiming a black win on that move. I'll post Soltis' suggestion, but I don't want to ruin it in this post if some want to figure it out first. Let me know if you want it!

May-26-10  PizzatheHut: I'm looking to purchase a new chess program to use as a post-game analysis tool. I've been looking at the various programs and am not sure which one to buy. Rybka appears to be the strongest, but the Chessbase suite of products is tempting too with Junior, Hiarcs, Shredder, and Fritz. Does anyone have a recommendation of where to start? I was thinking maybe Fritz 12 because I think it might be difficult to go wrong with such a versatile program. Any buying advice?
May-26-10  bharatiy: <pizzathehut> my two cents, if you have older fritz or chessbase program where you can run gui engine, I would suggest you download Stockfish for free, no point in spending money unless you are IM/GM level. Interface is key I believe, also stockfish is quite strong, better than Fritz just a notch below rybka.
May-26-10  mrbasso: <PizzatheHut> You could buy Fritz 12 and get Fire 1.3 UCI engine for free when it becomes available. Learn how to load it into Fritz. Then use it as favorite Analysis tool.
May-26-10  PizzatheHut: <bharatiy> and <mrbasso>, thank y'all very much for the recommendations, I really appreciate it. I'll look into both options.

Nov-29-10  The Rocket: Fritz is positionally very strong with a nice touch of dynamics, without rushing anything like some of the more aggressive engines.

I would say positionally and strategically as good as Rybka(maybe even stronger in some areas), but in tactics rybka prevails.

Oct-07-11  virginmind: yet another error in fritz 11 single core:

Analysis by Fritz 11:

1. (#1): 21...Kf7 22.Qh5+ Kxf6 23.Qg6+ Ke7 24.Qe6#

Oct-07-11  virginmind: <The Rocket> well, you dont need to be rybka to spot the mate in one move in this last position. weird still that although fritz did see that it's mate in one, it only gives that line, with a different, longer mate. ok, if black plays the indicated 21...Kf7 fritz immediatelly changes its 'mind' and gives 22.Qg6#. the problem though is that it didnt give that simple move before black's king (only) move.
Nov-26-13  virginmind: At depth 34, Fritz 11 (single core) has no clue this position is a draw:

  zanzibar: Generic operational question about Fritz - how do you get the count of games after doing a filter?

E.g. How do I determine how many games of Reshevsky's I have in a database?

In SCID this is trivial.

Premium Chessgames Member
  zanzibar: Doing a google search I came across this:

It recommends creating an ELO list, and then canceling out. The ELO list displays the game count as a side-effect.

If this is the best way all I can say is, "Are you kidding me?!"

Jul-09-15  Tomlinsky: <Frans Morsch, a Dutch professional computer chess programmer. Author of various dedicated chess computers and PC-programs. Frans, born in 1954, already started computer chess programming when he was thirteen years old. While studying physics, he started his career with his first program Nona written in 6502 Assembly, and after first tournament successes soon became professional chess programmer - his first dedicated chess computer was the Mephisto Mondial based on Nona. He further developed programs for Hegener & Glaser, Saitek, ChessBase and TASC, most notably his program Quest which in 1991 evolved to Fritz. After the release of Fritz 13 and 22 years of primary authorship, Frans Morsch retired from ChessBase on his own desire, the Fritz trademark continued by Gyula Horváth.>


Jan-06-16  GreenLantern:

The Fritz engine, since the very first iterations, was the brainchild and authored by only one programmer (in spite of rather humorous online rumors of a secret team): Franz Morsch. His engine deservedly became a legend, especially when it single-handedly defeated the super computer Deep Blue (still in prototype) at the World Computer Chess Championships in Hong Kong in 1995. As far as versions were concerned it was Fritz 3 running on a modest Pentium 90MHz.

Over the years Fritz has always been a top engine, providing players with top analysis, but after Fritz 13, the mighty Morsch hung up his hat, and the engine’s code along with him. In keeping with the tradition of a new and stronger engine than its predecessor, as well as new features in the interface, the Fritz 14 engine was signed by Gyula Horváth, and now the baton has been taken up by Vasik Rajlich.

After dominating the ratings lists and world championships for years and years with his engine Rybka, Vasik Rajlich eventually went off to greener pastures as he started a family with Polish IM Iweta Rajlich, and the throne was left vacant. After years of inactivity in the highly competitive computer chess field, he has returned, lending his skills to the next generations of Fritz, starting with Fritz 15.

ChessBase CEO Matthias Wüllenweber in Hamburg with Vas and Iweta Rajlich

The first question for the engine geeks or experienced players is: “Is this simply a rebadged Rybka 4?”

The programmer explains, “Fritz 15 is massively different from Rybka 4.1. The search is very different. I've spent the last six months mostly cleaning up certain aspects of the engine and setting up my infrastructure for testing, tuning, and various automation. It took me a long time (as well as insight from another project) to understand how this should all be structured. This isn't quite done yet but the core is in place. Although, there is very little Elo gain so far from that work. I see it as a foundation for the future.”

For the record, current testing by specialized computer lists such as CEGT and CCRL, among others, have evaluated Fritz 15 as being somewhere between 30-40 Elo stronger than Rybka 4, however Rajlich comments that he is currently working on Fritz 15.1, which will bring further improvements to its play.

In spite of their incredible ability, the engines have fairly distinct styles of play, much like humans, and whie you may find a brilliant attacking game by Petrosian, to quote an extreme, it is not the usual fare. How does Fritz 15 play relative to Rybka 4?

Vasik replied, “Fritz 15 will have a rather different 'search personality' than Rybka 4, but this won't be anything which is easy to summarize for users.”

Premium Chessgames Member
  AylerKupp: <GreenLantern> The latest (Jan-02-16) CCRL 40/40 has Rybka 4 rated about 35 points higher than Fritz 15 and the latest (Jan-03-16) CEGT 40/20 list has Fritz 15 rated about the same amount higher than Rybka 4.1. Both lists have Komodo 9.2/9.3 rated about 200 points higher than Fritz 15 so Mr. Rajlich has a lot of work ahead of him in order to catch up.

And the throne was never vacant. As soon as Houdini 1.5 was entered in the GCRL and CEGT lists it was rated ahead of Rybka 4.1, even though Mr. Rajlich was still active.

Jan-07-16  GreenLantern: Thanks for the info <AylerKupp>. I am a little surprised this has not caused more of a stir, even in the Rybka forums. I would have thought that the 'defection' of Vas Rajlich would have caused more commotion in the chess engine community - or maybe he's no longer that relevant. As you have stated, Komodo seems to be the new standard.
Jan-18-16  mrandersson: Fritz sparring mode is just the most unrealistic fake thing going. It often gives you a simple fork(normally a bishop knight pin with a pawn)you gain a minor player then it plays like a gm and you get smashed.

I play it on the hard(normal)setting and yea some games I win but most often it does that cheapo fake thing all the time. I even did a experiment with shredder on my mobile(Samsung note 4) set it to 2000 elo and low and be hold it lost.

There's no point it setting it to easy as it should be re named to take the piss. Does anybody else have that feeling with sparring in fritz 14(same in fritz 9 I have both)
