Based on Nelson's words @ Chatwing, about the probability that one can extract and pack the openings, i think it won't be a harm to share them now, months after. They were prepared from the archives of the previous event.

Refining from tons of logs to a simple file with just the necessary tags took me ~30 hours. I know, however, that it's nothing compared to the time spent for selecting them. Admirable work.

I hope the collection will be useful for testers.

There is an error in line position 1. Start with game #2 or any of your choise (fritz gui 14). Perhaps it can be edited and the line removed

Started with position 2 and ran 10 test games

ran fine ECO codes

A90
D45
B43
A87
A48

which if you openup the suite are the first 5 positions

Weird. Should be some issue related to text format but i've already used the set on Android without any problems.
I only have Arena on PC. Let me check and see.

With Fritz 14 gui I select engine , open position and open up the 454 database, at line 1 it states readerror1

If I use chessbase reader 13 and open a databaseTce6.. line 1 is blank

If I use chessbase 9, line 1 says text line 2 starts with a90 dutch as do the others

Interrestingly if I open with Arena line 1 is the A90 line 2 from the other sources.

Arena will probably run fine starting at game 1

I checked with Arena, Lucas Chess and even Fritz 5.32 which is a fossile. They all read all games without error.

Does Fritz 14 refuse to read the PGN? Or is your remark related to the way i've filled the PGN tags?

I've used white for the ECO + a short description of the opening and black for the shortest notation of 16 plies. This is the optimum solution to see what is the opening when you open the PGN in a chess GUI. There are many books available with ? all around. When you open them there's a list with nothing to tell you.

I wanted that the game list speaks so you don't have to open a game to see what's inside. This saves a lot of time when you need to manually collect your favorite positions and store them in a new, separate PGN.

Let me know if i did not understand your problem correctly.

First two openings are tagged like:

The file opens. Only Line 1 has a problem Fritz 10,11,12,14. chess reader 13, chessbase 9

1 readerror 1
2 a90 dutch......
3 d45 semi slav......
4 b40 Sicilian
5.........
6...........

All is normal from line 2 on

Hmm  just discovered if I change from full game header to header and moves the error does not appear

However cant get it to work as an opening suite from game 1

Seems engine starts to analyze from move 1

Ok

Was able to copy games from line 2 (A90 position1) to line 455 and paste into an empty database I created using chessbase 9. Started a test using new database and it started normally from game 1 using eco A90 Dutch defense. Will run a few games to see the opening suite functions normally

I do have a question however. How do you get the output you showed into a database ?

Your screenshot makes me think there's a text file formatting issue at the very beginning of the file.
Things that could help would be:
* trying to delete the first game (line 1) and keep the remaining,
* open the pgn into Arena and save all games into a new file, then try to load into your app.

The lines i've sent are taken from the PGN i've posted. PGN is just a text file that you can view and edit in text editors like Wordpad.

Maybe next time i should try another editor to prepare the PGN for better compatibility.

How can a database be created from something like that ?


Eurecka I think I figured it out

Cntrl A to select all
Cntrl C to copy

Just open up notepad or any text editor. paste data (cntrl V) and select file description all files and name the file with desired name.pgn.

i.e. random25.pgn

Chessbase can read this and use it as an opening database

Based on Nelson's words @ Chatwing, about the probability that one can extract and pack the openings, i think it won't be a harm to share them now, months after. They were prepared from the archives of the previous event.

Refining from tons of logs to a simple file with just the necessary tags took me ~30 hours. I know, however, that it's nothing compared to the time spent for selecting them. Admirable work.

I hope the collection will be useful for testers.

Hi

I am curious about something. The games are easily download from a TCEC archive site icon next to the season. I was able to download season 7 and truncate all moves after move 8 and create an openings data database 520 games (deleted 1 -4move game) 8 moves deep. I did so crudely by editing each game individually one by one using chessbase 9. Am I misunderstanding or missing something

No. Where time is mostly spent is when you want to optimize the tags. I wanted to show maximum info when the pgn is loaded and the game list appears. Most of the books you can collect on the web will display question marks, empty tags, few tags etc. I hate to open the games one by one to see what it is.
I did a lot of Excel to automate transfers and simplications. But it was too late too use this trick.
I think if i repeat this with TCEC-7, 4-5 hours will be sufficient. smile
