On https://rchess.de you can find a chess database program dedicated to repertoire management, running on Linux, Unix and Windows. A 100 page handbook and a sample database is included and a paper about repertoire management. Demos are also available in German and English.

Hi Gerhard,

looks like a new GUI database.

Topic: Transposition of moves (a topic on your site)
Really a topic!!

Example:
I have a database with around 80.000 position, around 40.000 are move-transpositions.
A PGN file from the first move to move 8, 10, 12 or 14 and cut.

Now, if I delete the move-transposition (pgn-extract is great) I create a questionable final result, why?
Deleted are often the correct—or rather, official—way to the ECO code.
In the database without doubles are now often not the correct way to the ECO-codes buildings.

Thats bad for an opening book for chess-engines.
A program should know the correct way to ECO-Code building and should delete the right move-transpositions.
Unfortunately, as far as I know, there isn't a program that can do that.

To the topic you wrote a bit on your site.
With many tricks before I delete move-transposition I can do a bit, but all this is a lot of work.

BTW:
I have added the link to your GUI in my link-selection:

Best
