How if all player in a game of cribbage have 12 points before the turn up. which card to turn up will make all player have 13 points?

In cribbage, players score points based on the combinations of cards they hold and the card that is turned up. If all players have 12 points before the turn-up, any card that can create a scoring combination with the players' hands, such as a pair or a combination that totals 15, would increase their score to 13 points. For example, if the turned-up card is a five, it could help players with pairs of tens or any other cards that sum to 15 or form a pair, resulting in a score increase for all players. Therefore, any card that fits those criteria would achieve the desired outcome.
