Promotion

A pawn is a soldier with a destination. Reach the last rank and it stops being a pawn, which is why one far-advanced passed pawn can decide an endgame. The change is part of the move itself: you push or capture onto the last rank and swap the pawn for a queen, rook, bishop or knight in your color. Because the choice does not depend on what was captured earlier, a second or third queen is perfectly legal. A queen is the usual pick. Underpromotion is the occasional exception. A knight can give check or fork a king and queen in a way a new queen cannot, and a rook or bishop can keep a game alive when a queen would leave the opponent with no legal move and so produce stalemate. Over the board, three details matter. A promotion by capture still means removing the captured piece. The choice is fixed once the new piece touches the promotion square, and the pawn does not need to be placed there first. If you press the clock without replacing the pawn, the move is illegal and the pawn is turned into a queen. Notation puts the new piece after the move, as in e8Q or exf8N.

Compare it with Pawn. The pawn moves one square straight forward, or two from its starting square, captures one square diagonally forward, and is exchanged for a queen, rook, bishop or knight on the far rank.

Compare it with Queen. The queen moves any number of squares along a rank, file or diagonal, provided the path is clear, which makes her the most powerful piece on the board.

A neighboring idea is Illegal move. An illegal move is one that breaks the rules of how a piece moves or leaves your own king in check; in over-the-board play it is corrected, and a second completed illegal move loses the game.

Knowing "Promotion" is the easy part; what to practice next depends on your rating, and the improvement plans by rating band list the habits worth building at each level.
