This week you can expect an update with support for variations containing repetitions. An example would be (don’t try before the forthcoming v1.2 update!):
- e4 Nf6
- Nf3 Ng8
- Ng1
putting us back to after 1. e4. Normally this isn’t part of someone’s planned opening — that would be weird from both players — but it can certainly happen if you’re just tapping around the board.
If you have any trouble, be sure to export your database and email the PGN file or post here so I have a sample of what’s wrong. Onward!
