9- Pawn promotion

 

In the early days of chess, a pawn that had pushed its way through the opponent’s lines and reached the opposite end of the board was promoted to a “mantri” (the Sanskrit word for “counsellor”) a weak piece that moved a single square on the diagonal. In the European version of the game, the mantri would become the queen and see its movement greatly enhanced. And that is how a promotion to the weakest piece had become a promotion to the strongest one.

​

Once again this is a rule that has varied greatly over the ages. Many players objected earlier on to the king having two queens – some still do – and for a while the pawn could only promote to a piece that had already been captured. At other times, a pawn could only promote to the piece of the file on which it promoted, or on which it started, with the exception of the king’s pawn which was permitted to promote to a queen since one could not, of course (!), have two kings.

​

Under the modern rules of chess, a pawn that reaches the last rank may promote to any piece (other than a king) at the player’s discretion. Known as the “unrestricted promotion rule”, it became popular in the 19th century and was almost universally accepted by the end of it. And since the queen is by far the most powerful piece of the game, it naturally follows that the vast majority of promotions are to a queen, a process that is usually referred to as “queening”.

​

A consequence of the new promotion rule was to make the material gain of a single pawn a much greater advantage than it initially was. Under the original rule, when a pawn could only promote to a mantri, a single pawn ending was always a draw since a mantri and a king could not force a mate. But with the introduction of the unrestricted promotion rule, a single pawn ending – if the said pawn could safely reach the last rank and promote – would usually translate into an easy win.

​

The rules of pawn promotion in Chess 99:

The rules of pawn promotion under Chess 99 return to the original philosophy of the game and promotions are now limited to the two minor pieces, bishops and knights, and nothing else! And there are other significant differences. A pawn reaching the last rank on a two-square move is not permitted to promote as part of the same play; promotion is delayed until a later play. (This will preclude any argument over the capture “en passant” of a pawn reaching the last rank on a two-square move.) And when such a pawn is eventually promoted, it is not permitted to capture an opponent’s piece as part of the same play.

​

Basic rules:

• A pawn that reaches the opposite end of the board – the “last rank” – on a single-square forward move may be promoted as part of the same play but that is not actually required; promotion may be delayed until a later play.

• A pawn reaching the last rank on a two-square move or on a diagonal move [to capture a piece] may not be promoted as part of the same play; promotion must be delayed until a later play.

• Promotion is to a knight or a bishop at the player’s discretion.

• The choice of piece is not limited to knights and bishops that have been previously captured.

​

Delayed promotions:

• A pawn standing in the last rank may be promoted whenever the player has the move.

• The promoted piece may make a move as part of the same play but is not required to do so; “on-the-spot” promotions are permitted.

• If the promoted piece does make a move, it is not permitted to capture an opponent’s piece as part of the same play.

• If the promoted piece does not make a move, no other piece may be moved in its place.

• The promoted piece will have all of its attributes on subsequent plays.

​

Do note the following:

1. A player will never have two queens, two paladins, or three rooks.

2. A player may however, have three [or more] knights and bishops.

3. You may never have both a promotion and a capture on the same play.

4. Since a king and a single knight or bishop cannot usually force a mate, a single pawn ending should be a draw.

5. Since a pawn that is being promoted may remain on its original square, this makes it the only play where a player is not required to actually move a piece.

6. Unable to capture a piece on the play when it is promoted, a pawn standing in the last rank does not attack any square.
