How likely is it to score a flush in cribbage and what strategies can be used to increase the chances of achieving this high-scoring hand?

Scoring a flush in cribbage is not very likely, as it requires all four cards in your hand to be of the same suit. To increase your chances, try to keep cards of the same suit in your hand and discard cards of different suits to the crib. This strategy can improve your odds of getting a flush.
