Problem with FRC PGN

[RubiChess]

Hi.

My first post...
I tried to import the PGN from this game https://tcec-chess.com/#div=frc4t&game=154&season=21 into Banksia but it seems to have problems with the castle move 10. O-O. Banksia only moves the rook to g1 instead of doing the complete castle.

Thanks for the report.

There are two problems with that game:
- PGN missing the tag Variant
- BSG has a bug in the second castle move (20. ... O-O-O)

The bug has been fixed for the next release

Okay, it works in 0.54 when I manually add the variant tag.
So my suggestion would be: If the tag is missing: Could you detect and set variant by reading the FEN? Like set chess960 when the FEN has [a-hA-H] castle flags instead of [kKqQ]? That would make it compatible to the TCEC pgns.

Thanks for your work on Banksia and best regards,
Andreas

Good idea, thanks. I will implement it soon!
