Start the game. The player with white pieces begins the game by moving one piece as described above. Turn then passes to black. Regardless of the moves, players always take turns. There is no doubling up or skipping.
If this is your first game, choose who gets white by a flip of a coin or, if both players are good sports, whoever is the weaker player. Generally speaking, white has a slight advantage.
If it's not your first game, the player who lost the previous game should play white.
Capture an opponent's piece by moving a piece into an occupied square. The captured piece is then removed from the board and does not return for the remainder of the game.
If we're getting serious, a player has to move a piece once he's touched it. If he only wants to adjust it, he must announce "adjust" before he places his hand on the piece.
Continue play with each player moving one piece per turn until the game ends. Making a move is compulsory; it is not legal to "pass", even when having to move is detrimental. Play continues until a King is checkmated or a draw occurs. Draws can occur in five scenarios:
Stalemate (The king is not in check but cannot move anywhere, and there are no other pieces left)
Insufficient material (The pieces on the board cannot checkmate at all, so no side will win or lose)
Threefold repetition (A position has been repeated three times, such as players moving pieces back and forth)
Fifty-move rule (Fifty moves have occurred since the last piece capture or pawn move)
Agreement (Players reach a consensus and agree to a draw)
