Yes of course, I know this kind of thing. But there remains technical
problems, along with performance ones. And the ratio value/cost is
really too low.

Scid will most likely not pass that at the one star level.

This is a good example of reasoning showing why we don't have correct chess

After supper, and while eating cream with maple syrup, I realize that we
could :
- use flags for the Ref-DB, where size and speed matters ;
- use PGN tags only when we are in specialized-dbs.
So monkeys and non-monkeys can have a ball.

Indeed.
Calming down now, I realize that we can live without Ids. I thought that
was a simple task. That is a real pity, from a reference point of view.
Still, I wonder how the DOI can survive Pascal's demonstration. Looking a

As a user, I use what I write. So it's not dead, even if it's slow. As a

Hello,
This gets more concrete !
1. The category tag could be used as a way to create books :
[Category "Castle Destruction"]
[Category "Isolated Pawns for the Advanced Player"]
[Topic "Rook Lift"]
[Topic "Double Bishop Sacrifice"]
We the notion of category could be interpreted

Hello again,
I just reread the monster thread about CentriScid. I can't synthetize
everything yet, as my notes are too big for now and I need to wash dishes
before bed. But I promised some feedback.
The discussion seemed at first to go in lots of direction, but that was an
effect of the sheer s
Hello,
To sum up more roughly :
- We need Unique Ids, as otherwise we're not dealing with any efficient
database model known to date ;
- We need Flags to speed up searches and normalize institutional work ;
- We need Keywords because users like to personalize their stuff : cf.

Hi,
To get a base for Scid that can be used for training (for example) and to
keep track of extra info, I think there is a workaround by mixing indexed
flags and PGN tags.
Each game can get one or several flags that are :
IDX_FLAG_START // Game has own start position.
IDX_FLAG_PROMO
