My other goal was to obtain a playable variant with all the 32 pieces used in standard chess, without lost of mobility due to the minor number of squares. The chessboard is composed of 24 normal squares, and 14 free areas. More than one piece of any colour can be located at the same moment in the same area. This type of move counts as an entire turn. This increases the mobility of the pieces and a player can have simultaneously two bishops of the same colour, or can move backward or laterally a pawn, etc.
All pieces capture as in normal chess.
Pieces en route cross the positions of the free areas according to the standard chess rules. The pieces only move out each one of the free areas with standard chess moves. Check or checkmate using the type of move described in 2- is allowed. These modifications do not change the movements of King and Queen, but the other pieces gain possibilities of displacement increasing their attack capacity. In addition, more configurations are possible, placing the free areas symmetrically in other sectors of the board.
