  **Description**

  Run in a terminal, Chess Opponent facilitates play chess without an onscreen board.

  The user plays on a physical board while inputing moves, reading Chess Opponent's
  moves from the screen, and updating the physical board accordingly.

  User moves are accepted either in standard algebraic notation (SAN) or in
  coordinate notation. Chess Opponent's moves are displayed in SAN.

  A SAN cheat sheet is freely available from
