Ορισμός και Σημασία του "cold card"

What is a "cold card"?

A cold card is a card that has not been played or revealed in previous rounds of a card game. Because it has remained hidden, players are unaware of its presence and do not anticipate it being part of the current play. This card is considered "cold" because it adds an element of surprise when it is eventually used or shown, as players have no prior knowledge or expectation of it being in the game. The appearance of a cold card can sometimes influence the outcome of a hand, especially if it changes the direction of play or helps form a winning combination.
