There are six kinds of chess piece: king, queen, rook, bishop, knight and pawn. The king moves one square in any direction, the queen any distance in any straight line, the rook any distance along ranks and files, the bishop any distance diagonally, the knight in an L-shape of two squares then one, and the pawn forward one square, capturing diagonally. Each player starts with one king, one queen, two rooks, two bishops, two knights and eight pawns.
Every piece except the knight moves in straight lines and is blocked by any piece in its path. The knight is the only piece that jumps over others.
These values are the standard guide used to judge whether a trade is favourable. They are a rule of thumb, not part of the laws of chess, and a piece's real worth depends on the position.
The pawn is the most restricted piece and also the one with the most special rules.
Yes. The king captures the same way it moves, taking any enemy piece standing on an adjacent square, provided that piece is not defended. Capturing a defended piece would place the king in check, which is illegal.
A king can never capture the enemy king. The two kings can never stand on adjacent squares, because moving next to the enemy king would put your own king in check.
