Nothing. You may be thinking of the 50-move rule, where if 50 moves happen without a capture or a Pawn move, the game is a draw.
If this happens to both players, than it is a stalemate (although it is usually 50 moves, the amount can vary)
In chess, the maximum number of moves you can make with only a king left is 5.
A draw by stalemate in chess happens when a player has no legal moves left, but their king is not in check. This results in a tie because the player is not in checkmate, but also cannot make any moves.
When only the king is left on the chess board, there are a maximum of 8 possible moves that the king can make.
A stalemate in chess happens when one player has no legal moves left, but their king is not in check. This results in a draw because neither player can make a move to win the game.
To avoid a stalemate in chess, a player should carefully plan their moves to ensure that their opponent's king is not left with no legal moves while not being in check. This can be achieved by maintaining active piece coordination and avoiding unnecessary exchanges that may lead to a draw.
There is no rule that says that if only a King is left, it has to survive by 30 moves or loses. The only rule in any way similar to this is that after 50 moves, no piece has been captured by either side AND no pawn has been moved during those 50 moves, then the game is a draw.
The king moves to the right side in chess.
In a game of chess, the king being the only piece left signifies that the game is almost over and the player with the king must protect it at all costs to avoid losing the game. The king is the most important piece in chess, and its safety is crucial for victory.
In chess, when a player's king is the only piece left on the board and all other pieces have been captured, it is called a "king versus king" situation. This is considered a draw, as neither player has enough pieces to checkmate the other.
Pawns capture pieces in chess by moving diagonally forward to the left or right onto a square occupied by an opponent's piece.
You lost when you lost your King. There is no purpose to playing after that.
