My son and I are rank chess amateurs, and we wanted to play our first "real" game where we keep track of moves to analyze later. We started the game but then realized that the board was reversed (i.e. the black pieces were on rows 1 and 2). Since we didn't notice until a few moves had been played, we just continued to use this reversed notation for the whole game.
The resulting PGN file doesn't want to import into lichess. Is there any way to take our "reversed" PGN game file and make it compatible? Perhaps some automated way to reverse the notation, or alert the PGN importer that the notation is reversed so it can handle it?
