I was thinking about how antichess isn't really the opposite of standard chess as the objective of standard chess isn't to capture all of your opponents pieces but to checkmate your opponent. I think something that could make for an interesting variant is one, with the opposite objective as standard chess, in which you win by getting checkmated.
The problem here is that you can't force your opponent to checkmate you, so idk how this would work.
There are positions, in which the only legal move for one player is to checkmate the other player.
For instance in this position if white plays Bb7 then blacks only legal move is Bxb7#
