Some chess variants are really helpful in teaching chess to beginners. Here is an example variant. This one is similar to knight chase. Both players have only a knight. White has a knight at a8 and black has one at h1. White starts first and then players make alternate moves. A player moves his knight and marks the square previously occupied by his knight. Marked squares are no longer available to any player. The player who cannot move his knight at his turn loses. This game is useful to teach the movement of knight to beginners in a fun way.
Are there any other chess variants that are actually helpful in teaching chess and fun to play at the same time? (I am not much interested in bringing in new pieces or new rules, focus is more on teaching chess rules the fun way). Thanks
