What is a blunder in chess?

One famous blunder in chess occurred in the game between Frank Marshall and Stefan Levitsky in 1912. In a critical position, Levitsky played a brilliant tactical shot that Marshall did not see, sacrificing his queen for a winning attack. However, Marshall, who was known for his resourceful play, found a way to turn the tables and ultimately won the game.

Blunders in chess can happen to even the most skilled players, and they often result in a significant disadvantage or even losing the game. They can occur due to oversight, miscalculation, lack of focus, or time pressure. It is crucial for players to stay alert and avoid making blunders in order to maintain a strong position and improve their chances of winning.
