misplays

Misplays are suboptimal actions in games, sports, or decision-making activities, where a move or sequence leads to a worse outcome than could have been achieved with a better choice. They can be a single incorrect action or a chain of decisions that compounds the disadvantage. The term is common in competitive settings but also describes everyday judgments that go awry.

In chess or poker, a misplay may be a blunder, a misread of the position, or a misjudgment of an opponent's intent. In team sports, it can be an ill-timed pass or ineffective positioning. In video games, mistimed abilities or suboptimal routes are considered misplays. In non-game contexts, misplays cover flawed strategic choices.

Causes include cognitive biases, incorrect risk assessment, misreading information, time pressure, fatigue, poor communication, and gaps in knowledge. Misplays can also arise from deception by opponents or from choices that are rational under uncertainty but reveal weaknesses when the true state is known.

Evaluation compares outcomes to an assumed optimal plan and examines the reasoning available at the moment. Not all misplays are equally costly; some reflect necessary risk, while others expose persistent flaws. Analysis aims to reduce future misplays through study of decision processes and deliberate practice.
