The basic movement for each piece is the same as traditional chess.
+Pieces are never removed from the board. Instead, the capturing piece shares the square with the captured piece, and the two pieces become a joined pair.
+When either piece moves from a square containing two pieces, the other piece moves with it. + Each player can only move a joined pair according to the rules for their own piece. Joined pieces cannot capture other pieces.
+A free (non-joined) piece may move into a square occupied by pieces of both colors. + When it does, the other piece of the same color becomes a free piece and must move to a new location following the normal movement rules. + This process may be repeated multiple times in the same turn.
+Ŝako (checkmate) occurs when an opposing piece joins with the king. + Important: The king is not permitted to join with (capture) other pieces.
+Due to joined movement, it is possible for a pawn to be moved backward to, or past, its starting row. + Pawns may move forward two spaces from either of the first two rows on their own side of the board.
+When a pawn is captured en passant while joined with another piece, the captured pawn moves back one square to become joined with the capturing pawn + and the joined piece from the capturing side moves to a new location from its original position as with any other capture.
+Pawns are promoted when they reach the final row on the opposite side of the board, even if they were moved there by the other player as part of a joined pair.
