Everyone knows the true value of a pawn is that they can, if they survive, become a queen. And if chess pieces were people, those that cared for that pawn may be concerned by the process. Would the pawn remember the other pawns that it had once fought beside or are they now expendable.
A lot of people forget about castling however. Wikipedia says this about the rule:
Wikipedia wrote:Castling is a move in the game of chess involving a player's king and either of the player's original rooks. It is the only move in chess in which a player moves two pieces in the same move, and it is the only move aside from the knight's move where a piece can be said to "jump over" another.
Castling consists of moving the king two squares towards a rook on the player's first rank, then moving the rook to the square over which the king crossed. Castling may only be done if the king has never moved, the rook involved has never moved, the squares between the king and the rook involved are unoccupied, the king is not in check, and the king does not cross over or end on a square in which it would be in check. Castling is one of the rules of chess and is technically a king move.
If one can't make a pawn into a queen, they might just choose to use a Rook to guard their king.
Happy Hunting!
