A bridge ploy is a strategy used in the card game bridge. It consists of five elements: rebid (5 letters), ECHO (4 letters), RUFF (4 letters), FINESSE (7 letters) and jumpbid (7 letters). Rebid is when a player bids again after their partner has already bid, ECHO is when a player bids the same suit as their partner, RUFF is when a player trumps their partner's suit, FINESSE is when a player tries to win a trick by leading a card from a suit in which they are weak, and jumpbid is when a player makes a higher bid than expected.
