(1)The king moves to any adjacent square that is not attacked by one or more opponent's pieces, The opponent's pieces attack a square even if those pieces themselves cannot be moved, or
(2) "castle". It is a move of the king and one of the rooks of the same color on the same horizontal, which counts as one move of the king and is performed as follows: the king moves from its original square two squares to the sides to the rook (jumps one square), then the rook moves to the square just crossed by the king (the jumped square).

the queen can move all the squares vertically, horizontally or diagonally on which she stands, but she cannot jump over pieces in her path.

The Rook can move all vertical or horizontal squares on which he stands, but he cannot jump over pieces in his path.

The Bishop can move on any square on the diagonal he is standing on, but he cannot jump over pieces in his path.

The Knightcan move to one of the squares closest to the square he is standing on, but not on the same horizontal, vertical or diagonal.

The Pawn
can move forward to the unoccupied square of the same vertical immediately in front of it, or:
(2) on its first move, the pawn as an alternative to (a) may advance two spaces along the same vertical, provided both are free, or
(3) the pawn may move to a square occupied by an opponent's piece diagonally in front of it on the adjacent vertical by taking that piece.
(4) When a pawn reaches the last row of its starting position, it may be replaced as part of that move by a queen, rook, knight or knight of the same suit. The player's choice is not limited in terms of previously taken pieces. This replacement of the pawn with another piece is called "producing" and the new piece immediately comes into play.
