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.

Hello guys, My name is Shashwat and I made this app chess9 to play and enjoy the game for fun it has luxury board where pieces are made up of black and gold color. Please feel free to check features like Check, Checkmate, Castling, Pawn capturing to opposite board and progressing to Queen. Guys, when you play the game the opponent is meant to be very easy so everybody can learn, progress, try different moves and grow and be the best at their own pace. So definately give it a shot and keep growing and learning. Thank you!
