A feint attack in fencing serves the purpose of deceiving the opponent. It is a false attack intended to provoke a reaction from the defender, which in turn creates an opportunity for the attacker to land a successful blow. The feint is designed to be convincing enough that the opponent attempts to parry it, revealing an opening for the attacker to exploit. This tactic is crucial as it allows the fencer to assess the opponent's reactions and patterns, and to mislead them about their timing, target placement, and intention. The effectiveness of a feint lies in its ability to create a false impression and manipulate the opponent's actions, providing the attacker with a strategic advantage. As mentioned in various sources including Quora and the Wikipedia glossary of fencing, a feint is recognized as an offensive movement resembling an attack but intended to miss,诱使对手做出反应，从而为真正的攻击创造机会。
