Through the Looking-Glass, and What Alice Found There (1871[1]) (also known as "Alice through the Looking-Glass" or simply "Through the Looking-Glass") is a novel by Lewis Carroll and the sequel to Alice's Adventures in Wonderland (1865). Alice again enters a fantastical world, this time by climbing through a mirror into the world that she can see beyond it. There she finds that, just like a reflection, everything is reversed, including logic (running helps you remain stationary, walking away from something brings you towards it, chessmen are alive, nursery rhyme characters exist, etc)
Climbing up onto the fireplace mantel, she pokes at the wall-hung mirror behind the fireplace and discovers, to her surprise, that she is able to step through it to an alternative world. In this reflected version of her own house, she finds a book with looking-glass poetry, "Jabberwocky", whose reversed printing she can read only by holding it up to the mirror.
Through the Looking-Glass is based on a game of chess, played on a giant chessboard with fields for squares. Most of the main characters are represented by a chess piece, with Alice being a pawn.
if Alice is a Pawn and Hillary = Alice than Hillary is a Pawn.
