Ορισμός και Σημασία του "responder"

Who is the "responder"?

In card games like bridge, the responder is the player who answers their partner's opening bid during the bidding phase. After the opener makes their bid, the responder evaluates their hand and decides how to respond, either by agreeing with the bid, making a new bid, or passing. The responder’s goal is to help determine the final contract by providing information about their hand's strength and suit preferences. The responder works with the opener to find the best strategy for winning the hand, based on the cards they each hold.
