Has the position after 10....Kd6 occurred earlier in this game? If yes, the engine thinks it's a repetition and shows "0.00".
More information on the repetition issue can be found on this thread on TalkChess, a forum dedicated to computer chess.
ChessBase products only support two protocols:
1) Their own proprietary (used by the .eng engines)
2) The UCI (used by by many commercial / open source engines)
You must see a "Create UCI Engine" option in either Fritz or ChessBase (I used it all the time to make tournaments between engines).
I also use Arena for engine tournaments and supports both UCI /...
Well since the protocols creating cbv, cbf and cbh formats are not made publicly available, one will certainly not find any such conversion tool (i.e. unclear how they are encoded to reverse them to pgn).
Other reason maybe that the difference between all these formats is just due to an "incremental encoding" that is being used, which means that for it to ...
In Chessbase, copy the games to a temp database, right click the file, go to tools and select Unannotate db, then copy to the games to a pgn file.
Edited to note Unannotate doesn't work on pgn files directly.
Fritz's 2.Kf5 is a mistake because 2.Kd5 is the only winning move according to the tablebase. Maybe Fritz suffered from the horizon effect (couldn't see far enough ahead) which turned the win into a draw. After that, a draw by repetition doesn't seem unreasonable.
Playing black, Fritz resigns but that's after seven moves, so the "horizon" is now closer, ...
I also have PowerBook 2019, and Stockfish 10, and I can confirm what you found, but there is an explanation.
The moves suggested in the PowerBook are from actual human games. They are intended, specifically, to give the computer a human opening book, rather than it just playing on its own. You will find these games in the database Powergames2019 that came ...
Fritz 17 is really just the same Chessbase GUI bundled with a chess engine Fritz 17. Depend on what version you buy, your Chessbase product may come with MegaDatabase - a huge collection of master chess games. Fritz 17 doesn't give you that.
Fritz 17 is not a public chess engine in the sense that it only works for Chessbase. I'm not aware it runs on ...
Scidb can do it.
Here is how
Open the CBH database.
When it is opened, go to the Database tab.
Right-click on the rectangle of the CBH database and click on Export.
Choose PGN or any other format.
Enter the filename and click on Save.
The only drawback of Scidb for now is that it cannot unarchive .cbv file by now.
I made to tool to unarchive .cbv files. ...
Go to Engine->Change main Engine... All you have to do then is select StockFish and click OK. Then click on New Game icon and the change will be applied, you should see title change from Fritz to StockFish. All that is left is to setup a position and run analysis...
It is not possible to do this in chessbase reader. You can use Arena Chess (free) to do this then transfer this .pgn into Chessbase Reader. Reader allows me to use Chessbase products for training but to evaluate my own games I use Arena.
It's not possible, in fact in "Chessbase reader", there is the word reader which means you can only pgn (or .cbh ...)
If you want to do such thing, my advice is for you to get a copy of the most used software like Chessbase or Fritz.
Probably there is some free stuff which are doing the same but I don't know it.
"Move 26" (or thereabouts) is the "midpoint" of most chess games.
Your opening tree application appears to working fine in getting you to the peak or "combustion point" of most games. (That seems to be its purpose.) From there, it's mostly downhill.
The company ChessBase sells a series of engine GUIs (Fritz, Houdini, Komodo, Rybka) that blundercheck or do full game annotation. The ChessBase program lets you run an engine while you go through a game, or can add games with a similar opening, but it won't do an automatic full game analysis the way that the engine GUIs do.
A .cbh file is not a complete database. A database in Chessbase format consists of multiple files.
To backup or transfer Chessbase databases between computers, you can either:
Backup in Chessbase to a .cbv file
Save games in portable PGN
Take a look at chesstempo. You can use their online database free up to so many moves and then they want you to pay to search deeper. I used to use chesslab.com which was great for searching positions, but it uses a vulnerable version of flash -- if you can deal with that it is a nice resource.
chess-db.com claims the biggest database (which is not ...
Thanks for your answers. I have contacted ChessBase and they told me that training annotation is not supported in PGN files but just in their original database format cbh. So, there is nothing to be done about this problem.
I used the following python script using python-chess library :
def KPvK_up_to_symmetry_export_to_FEN_func(pgn_file_path, nb_games, output_pgn_file_name):
output_pgn = open(output_pgn_file_name,"w+")
games = 0
pgn_file = open(pgn_file_path, encoding="utf-8-sig")
while nb_games == 0 or games < nb_games:
I am not sure what you are doing wrong. I get plenty of games that way. It is possible you did a previous search that still has some residual information in the "search mask" (this is what ChessBase traditionally called the search feature).
I will first show you how to do that and get results, and then I will show you one or two better ways. First, as you ...
Unfortunately, many of the statistical functions of the Opening Book feature in ChessBase have been unreliable in every version I've owned.
For example, after the Caro-Kann line 1. e4 c6 2. d4 d5 3. e5 Bf5 4. Nf3 e6 5. Be2 Nd7 6. O-O h6 7. Nbd2 Ne7 8. Nb3 Qc7 9. Bd2, the opening book PowerBook 2013 shows this table:

Here is a simple way to do exactly what you want:
Open the .cbv file in ChessBase Reader
Select all the files you would like to convert to .pgn (Ctrl-A to select all files)
Go to File at the top left corner and press Selection To Text file
You will receive a popup where you should select PGN under Format and press OK
Save the .pgn in your designated area ...
There is now a CBH to PGN app for Android (only handles CBH files, not cbv) - https://play.google.com/store/apps/details?id=org.chess.cb&hl=en
I personally would like to see this available as a command line utility on windows.
When I converted the 2014 ChessBase Database to PGN format, and finally to SCID format, I used VirtualBox (x86 and AMD64/Intel64 virtualization, for which you need to install Windows and ChessBase) because I sure what Windows programs run perfectly with it. However, I don't know if your hardware is powerful enough for a virtualization
