A blunder is a spectacularly bad decision or action, a mistake or error with detrimental consequences to the party that makes it.

Naturally many sensible decisions, which even in retrospect were carefully taken, may also prove disastrous mistakes.
In chess, a blunder is a very bad move which is quickly recognised as a very bad move by the player who made it, typically before or directly after his opponent has made his reply move. They are usually caused by some oversight, whether from time pressure (see time control), overconfidence or carelessness. While blunders may seem like a stroke of luck for the opposing player, some chess players give their opponent plenty of opportunities to blunder.
