For regular chess, I use SCID and it works well. It has database searches, position searches, player stats, and a nice compact file format (i.e. not PGN, which is inefficient and big).
Is there any similar software like the SCID software mentioned above, but for chess variants? I've tried Winboard/XBoard (it reads from PGN, so is slow and bulky, plus it has a slightly stunted search).
An example use case: I would like to organise/search/use a database of only antichess or only atomic games. I should be able to do all (or at least some) of the following:
- Save/load the database to and from PGN
- Save/load the database to and from a more compact format than raw text PGN (compare SCID .s*4 or ChessBase .cb* formats for regular chess)
- Search for games by date/player/rating (or more generally by tag)
- Play through the games in a GUI (or at least give me a PGN of individual game(s) I view)
Engine support is not a must.
