Chess, noun
A game for 2 players, each of whom moves 16 pieces according to fixed rules across a checkerboard and tries to checkmate the opponent's king
One of those earlier games was a war game called Chaturanga, a Sanskrit name for a battle formation mentioned in the Indian epic Mahabharata. Chaturanga was flourishing in northwestern India by the 7th century and is regarded as the earliest precursor of modern chess because it had two key features found in all later chess variants—different pieces had different powers (unlike checkers and go), and victory was based on one piece, the king of modern chess.

Set up the chessboard with a white square in the bottom right-handed corner. The easiest way to remember this is with the phrase "white to the right." If your board has numbers down the side, the line ("rank") with a 1 next to it goes on the side where you'll line up the white pieces.
Set up the pawns in the second row (rank). In the first row (rank) place the rooks in the corners, then working in from both sides place the knights then the bishop. Finally, place the queen on the same color square and the king in the final spot.
Start the game with all of the pieces facing each other on the back 2 rows of each side. Put the pawns in front, then line up the other pieces symmetrically with the king and queen in the middle.
Learn how each type of piece moves. Each player controls 16 pieces: 8 pawns, 2 bishops, 2 knights (little horse heads), 2 rooks (little castle towers), 1 king, and 1 queen. Each type has its own way of moving across the board and potentially capturing your opponent's pieces as it goes.
There are a few special rules in chess that may not seem logical at first. They were created to make the game more fun and interesting.
This move allows you to do two important things all in one move: get your king to safety (hopefully), and get your rook out of the corner and into the game.
On a player's turn, they may move their king two squares over to one side and then move the rook from that side's corner to the right next to the king on the opposite side. However, to cast, the following conditions must be met:
It must be that king's very first move
It must be that Rook's very first move
There cannot be any pieces between the king and the rook to move
The king may not be in check or pass through check
