What happens if the king reaches the other side in chess?
Likewise, can you win chess by getting your king to the other side?
Does a player win when his king reaches the opponent's side of the board? There is no rule that a player can win by moving his king to some position. A game of chess is won by mating the king of the opponent.
Beside above, what happens when a pawn reaches the other side?
When a pawn reaches the opposite side of the board, it promotes. This means that the owner of the pawn can replace it with a queen, a rook, a knight, or a bishop of his own color, and put that piece instead of the pawn on the board on the square of the pawn.
When a pawn reaches the other end and becomes a queen where is the queen placed on the board? The pawn that reaches the end square is promoted to a queen on the spot. It is not moved from the square it is promoted on, and as soon as it touches the square it is a queen.
