What is finesse and how is it used in the game of bridge?

Finesse in bridge is a strategic technique used to win tricks by playing a card in a way that maximizes the chances of success. It involves leading a card from a weaker hand in the hope that an opponent holds a specific higher card. This allows the player to potentially win the trick with a lower-ranking card. Finesse is used to gain an advantage in capturing tricks and ultimately winning the game.
