The Romantic Chess Variant is normal chess except that pawns must promote to knights.
This is meant to discourage playing for a better endgame as a winning strategy, effectively promoting direct mating attacks as the only realistic way to win the game.
This definition of the Romantic Chess Variant was conceived and brought into life on 2017-12-31
when Michał Ryszard Wójcik (the owner of Apronus.com) modified the chess engine used on Apronus.com and showed it to a number of friends.
This modified chess engine has been publicly available to play against since 2019-06-04.
