The Idea
Chess variants are chess-based games, but with a number of changes.
This chess variant is characterized by the absence of the traditional black and white squares on the chessboard. In other words, the space is not divided into squares, but all positions on the "chessboard" are allowed. Obviously also the moves of the pieces are modified although they derive from the traditional moves.
In this way, the game tree of moves becomes innumerably larger so, the strategy become more important than the tactic.
The philosophy of the game is based on the rules of traditionally chess with some simplification but without squares. In other words, we pass from a digitalization of space (chessboard) to a continuous space.
