Asymmetric Augmented Knight
Chess variant where the knights are extended with a new power, but different for the two players. There are four possibilities to choose from for both side.
Otherwise the rules of chess apply, with the following difference:
Since there are four choices for each colour, but these cannot be the same in this game (only in the symmetric variant: Augmented Knight), therefore there are 12 possibilities to play this game.
