Infinitesimal Chess (ε Chess for short) is like regular chess, but each piece can move a fractional amount. Pieces move along the same paths as in normal chess, but can stop anywhere along that line. If your piece, which has a size, overlaps one or more opponent's piece, you take them. The game ends when you take the opposing king.
