Hi all,
         Felix once mentioned Fritz 8 as the best GUI for Rybka. Now I am using it but I am not familiar with it :-).So somebody please suggest some tips to optimize Rybka in Fritz 8.

Basically, you can always trust the default settings of engines. Set a reasonable hash size (not too large!). For interactive analysis though, Rybka should be switched to 'Preserve Analysis ON'.

For general enhancement of (late) endgame analysis, read in your Fritz F1 help about: Tablebases

(the complete 3- and 4-piece tablebase files are most probably in a directory \TB on your Fritz CD)
Parent - - By RAM MADHAV MOHAN (**) Date 2007-12-26 15:20
Yes. There is a Nalimov tablebase generator in the CD. But it is taking a long time to build one into the Hard Disk.

so why is fritz 8 best gui to use rybka in?
Parent - By Felix Kling (Gold) Date 2007-12-26 18:06 Edited 2007-12-26 18:18
That's my personal oppinion. It's because it supports .ctg books, doesn't cost as much as a new Fritz and is quite similar to the newer Fritz versions. Since the Rybka 3 GUI will support ctg books (i.e. convert them to another format), my recommendation will change in some months :) .
Parent - - By Permanent Brain (*****) Date 2007-12-26 15:32
No, I don't mean the tablebase generator. I mean the tablebase files themselves, ready to use. Usually, a ChessBase playing program CD (Fritz etc.) contains the 3- and 4-piece Nalimov tablebase files. Do you see other files in that directory, ending with .emd? These are the tablebase files.

If you don't have them: The Arena site provides an easy download, ~30 MB
(scroll down for "4-pieces

That set is good to start with; you can search or generate 5-piece tbs. later.
Parent - - By RAM MADHAV MOHAN (**) Date 2007-12-26 15:52
There is no file in the TBs folder ending with '.ernd' :-(. I already have that 4 pieces tablebase =29.6MB. But, is that enough?
Parent - - By Felix Kling (Gold) Date 2007-12-26 18:03
You can find links to the tablebase files and some more information here:
Parent - - By RAM MADHAV MOHAN (**) Date 2007-12-26 18:13
Thanks for the link Felix. Some huge tablebases there. I am having a sleepless night in front of my computer, generating TBs.I will surely miss the test match :-(.
Parent - - By Felix Kling (Gold) Date 2007-12-26 18:16
Generating tablebases is not necessary. Just follow the links on the page I linked to, there you can download the 5 men tablebases. For the 6 men you will have to use a program like emule. (You can download the 5 men here: )
Parent - - By RAM MADHAV MOHAN (**) Date 2007-12-26 18:24
Just leave TBs. Actually I created this topic for getting some tips about the Fritz GUI. I am not familiar with it. The help option in the program is not helping me much. I dont know much about the settings in Fritz 8. Its very different from Arena.
Parent - - By Felix Kling (Gold) Date 2007-12-26 18:40
You just need the windows board, notation/book (you can use one window for both, at the top of the window you can select what you want to see) and engine, so close the clock window. The most important commands are on the top of the window available as buttons. The most things in the GUI are quite intuitive, so if you work with it some hours everything will become more clear.

If you have problems it would be helpful if you say what exactly the problem is.
Parent - - By RAM MADHAV MOHAN (**) Date 2007-12-26 19:11
In book options, which is the best setting to get the maximum performance: Normal  or Optimal settings? Will Rybka play better moves (when compared to Arena) in the Fritz GUI due to the influence of that giant openings book?
Parent - - By Felix Kling (Gold) Date 2007-12-26 19:22
You should use one of these books or RybkaII.ctg to get the maximum performance. The standard Fritz book is quite good for normal opening theory but the Rybka II.ctg e.g. is optimized for computer chess and Rybka. Btw., the standard Fritz book isn't gigantic, to get a gigantic book import the games of a huge database in the Fritz book (edit->book or sth. like this) , then you have one :-D
Parent - - By RAM MADHAV MOHAN (**) Date 2007-12-27 04:40
      Are you saying that the Fritz8.ctg is not better than the other Rybka books? The size of that book is large when compared to some other books. Thats why I said its a giant :-). Will it be effective if I import another book?
Parent - - By Permanent Brain (*****) Date 2007-12-27 05:33
No, I would not recommend to mix big books and things like that. Even less if you are not familar with your program yet. Why do you want to change it, anyway? Why not simply use Fritz8.ctg for Fritz and RybkaII.ctg for Rybka (or any combination of book+engine you like)? There are no big secrets about that. Browse the books, see what they play, make your choice. Both are big top level books created by book experts.

Did you take a look in your book window, with them?

With products like Rybka and Fritz, it is NOT intended that the user must search dozens of secrets and do lots of optimizations. Just configure it reasonably (for that, your F1 help info in Fritz, Rybka FAQ and such infos are sufficient). Maybe advanced questions will arise when you are familiar with the interface and have read the basic informations etc.

Also, there is a saying 'Don't fix it if it ain't broken.' :-)

Of course, another thing would be if you go for the rank #1 in Playchess engine room. In that case, you will have to figure out things yourself EVEN MORE. Also, you'd need a comp with 32 CPU cores :-D If it were so simple that with a couple of tips, 1,2,3, go! one could achieve anything there, anybody would be #1. - But maybe that is not what you intend anyway.

For the normal things like analysis, training, studying games... the basic equipment is sufficient.
Parent - - By RAM MADHAV MOHAN (**) Date 2007-12-27 10:59
I just use it for analysis and training (I have no intention to play at Playchess engine room because I am using a 32bit processor and I only have a small amount of memory :-) ).Fritz 8 is more than enough to do these tasks.I just wanted to set the optimal GUI settings for Rybka.I thought some dramatic changes should be made in the GUI when we introduce a new engine into it.As I said earlier I am a newcomer into this field and I am learning from these posts from experts like you.Thank you very much for the help.
Parent - By Vasik Rajlich (Silver) Date 2007-12-27 13:12
It really is as simple as Permanent Brain says. Load the UCI engine, load the RybkaII.ctg opening book, and you're ready to go.

And yes, I would recommend RybkaII.ctg as an opening reference, it's better (and newer) than the Fritz book.

Parent - - By RAM MADHAV MOHAN (**) Date 2007-12-27 17:43
I did not find the ponder option in Fritz. I only found the Permanent Brain option :-). Do they have the same function or is it my carelessness?
Parent - By Vempele (Silver) Date 2007-12-27 17:58
They're the same thing.
Parent - By Henrik Dinesen (***) Date 2007-12-31 11:43
With regard to the GUI, have a look at
Parent - - By Gaмßito (****) Date 2007-12-29 05:31
I do not understand why Felix said that Fritz 8 GUI is the best GUI for Rybka. That is a very old GUI and have some problems. 

You should use Fritz 11 GUI. It is the best. The newest GUI is always the best choice.

Parent - - By Permanent Brain (*****) Date 2007-12-29 08:35
I am almost sure that many would disagree. I have repeatedly seen problems being reported with the new Fritz GUI editions each, which the older versions did NOT have and which require(d) a bugfix. Also, the older versions can be better because for them, there were more bugfixes already :-)

But I use ChessProgram8 still just because I don't have a newer Fritz type program. For that, an update from Jan. 19th 2007 is available:

It is stable and reliable, as far as I can tell, also in Windows Vista. From the novelties of the newer versions, I'd mainly like to have the improved board graphics which I saw in CB. Light 2007, and maybe the graphical smileys on the server as a fun factor. But that are not important things and I can wait for an 10 Euro F9 edition. :-D (not sure if that will be made though)
Parent - By Jessica (**) Date 2007-12-29 11:29
I'm going to have to agaee with Permannent Brain I love the older GUI's because seems like less problems than the newer one which goes to the question "if it aint broke why did they fix it" because I can see nothing wrong with ANY of the older GUI's infact I do alot of online chess playing and most people that use the newer GUI's crash or something but my OLD GUI is still a ticking :-)
Parent - - By Felix Kling (Gold) Date 2007-12-29 11:52 Edited 2007-12-29 12:01
I don't see a big difference between Fritz8 GUI and Fritz 11 GUI, also Fritz 8 is much cheaper. That Fritz 8 has more problems thatn Fritz 11 is not true. The newest GUI is NOT always the best choice,  it's like when you buy a car, it's not always clever to buy a new one...
Parent - By Jessica (**) Date 2007-12-29 12:18
I think Fritz 8 is about as perfect GUI as we will see.  Remember "AGE before Beauty!" :-D
