Knightmare Chess 2 plays as a stand-alone game or as a expansion to the original release. Knightmare Chess 2 adds even more unpredictability to the occasionally stale game of standard chess or the original Knightmare Chess modified game by giving players 80 more cards that they can play before, after, or sometimes instead of their turns. Big fun for an evening of relaxed chess play, but again, not recommended for purists.Expands: Knightmare Chess - BoardGameGeek
