How many illegal moves are allowed after chess?

Answered by Michael Wilson

In chess, players are expected to adhere to the rules and make legal moves throughout the game. However, there are instances when a player may make an illegal move either due to a mistake or intentionally. To address this issue, the FIDE Laws of Chess specify the consequences for illegal moves.

According to the FIDE Laws of Chess, a player is allowed to make two illegal moves before any penalties are enforced. The first two illegal moves are considered minor infractions, and the arbiter, who is responsible for overseeing the game, will give the opponent two minutes of extra time for each of these illegal moves. This penalty is aimed at compensating the opponent for the time lost due to the illegal move.

The purpose of giving extra time to the opponent is to maintain fairness and ensure that both players have an equal opportunity to compete. By providing additional time, the arbiter aims to offset any advantage gained by the player who made the illegal move. This penalty also serves as a deterrent to discourage players from making illegal moves.

If a player makes a third illegal move in the same game, the consequences become more severe. In this case, the arbiter has the authority to declare the game lost by the player who made the illegal moves. This means that the opponent automatically wins the game, regardless of the position on the board at that moment.

The decision to declare the game lost is a significant penalty and is meant to discourage repeated illegal moves. It emphasizes the importance of playing within the rules and maintaining the integrity of the game. By enforcing such a penalty, the arbiter ensures that players take responsibility for their actions and face consequences for violating the rules.

It is worth noting that the penalties for illegal moves may vary depending on the specific tournament or event. While the FIDE Laws of Chess provide a general framework, individual tournament organizers may have their own set of rules and penalties for illegal moves. Therefore, it is essential for players to familiarize themselves with the specific regulations of each event they participate in.

To summarize, in chess, a player is allowed to make two illegal moves before penalties are enforced. The arbiter will give the opponent two minutes of extra time for each of the first two illegal moves. However, if a player makes a third illegal move, the arbiter has the authority to declare the game lost by that player. These penalties are in place to maintain fairness, discourage illegal moves, and uphold the integrity of the game.
