Support 3check pasting of other FEN variants

Open magehrke opened this issue 4 years ago • 2 comments

LiGround currently only supporst 3check FENs like this:

rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 3+3 0 1

It would be nice, if LiGround would also support the same position, but in a slightly different FEN that is widely used (e.g. by lichess.org). In this notation the same position would be
```
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1 +0+0
```

The FEN parsing in the core engine actually already supports that, so I assume it is only rejected in the ffishjs FEN validation.

FEN validation will support it in the next ffishjs version: https://github.com/ianfab/Fairy-Stockfish/pull/398
