Alice Chess is a popular variant where the pieces, like Lewis Carol's heroine, go "through the looking glass" to a Mirror board and then back to a Normal board. Curiouser and curiouser, you can use a single board to represent the Normal and Mirror boards at the same time.

The file contains five variants:

• Alice Chess The variant invented by V.R. Parton in 1953
• Alice Mirror Black pieces start on the Mirror board
• Alice Zero Pieces can switch board while staying on the same square
• Alice Grand An Alice version of Christian Freeling's Grand Chess
• Alice Extinction An Alice version of Extinction Chess
