What are Chess pawn promotion rules?

Answer 1

The pawn can move 2 tiles forward on its first move. Then, it can only move 1 space each turn. If one of your opponent's players is 1 space diagonal from your pawn, it can capture it but moving 1 space diagonal and taking it. When a pawn reaches the other side of the board, it can change places with any player that has been captured. The promoted pawn can become any piece it chooses to be. It is not limited to other pieces that have already been captured. Thus it is possible for a player to have more than one Queens on the board. The pawn becomes another piece; it is not exchanged for a captured piece.

A pawn is the weakest piece on the chessboard, hence the name; nevertheless, they are very important. Pawns can only move one space straight forward, unless the specific pawn hasn't moved yet in the game, where they can move two. Pawns can only capture another piece diagonally (but not backwards and to the side.) When a pawn makes it all the way to the other side of the board, you get to "promote" it into your piece of choice, but not a king. Also, pawns are the only pieces that can to "En Passant, which is very hard to explain, but it is a special type of capture.

Answer 2

A Chess promotion occurs when one of your pawns reaches the opposite side, where it can then turn into any other piece besides a king. This is a very powerful maneuver, and one must stop an opponent from doing so lest he get another powerful piece.
