I was watching a video online about how the Staunton chess set became the international standard, and one of the reasons given was that it makes the pieces easily and quickly distinguishable to both players. And since one of my greatest muses is spite, my immediate thought was, "What if the opposite." I call this chess variant Memory Chess. This chess set features six different pieces as usual, but the only distinction between them are the symbols on the bottoms, which can only be seen when the pieces are turned over.

The rules I've come up with for this mess are exactly like regular chess, but with two important additions:

1. All pieces are revealed before the game starts to ensure that the board is set up properly.
2. At any point between turns, the player whose turn it is (who has not yet taken their turn) may accuse the other player of having just made an illegal move due to misidentification of a piece (or pieces). If they do so, the piece just moved is revealed (along with any other relevant pieces, in the case of something like check or en passant). If the accusing player is correct, the turn is undone and it remains the accusing player's turn (the other player loses their turn). If the accusing player is incorrect, the other player gets another turn (the accusing player loses their turn).

Supports are theoretically unnecessary, but they might help keep the pieces from popping off the bed midprint. I didn't use them for the pieces in the photos, but there were a few... incidents, so use your best judgment.

Have fun!
