What is Double Gutshot/Belly Buster in Poker?

A Double Gutshot (or Belly Buster) is a straight draw that does not include consecutive cards and can be completed by two different rank cards. In other words, the player has two inside straight draws at once. “Doug held K♠ 7♠ and the flop came 9♣ T ♣ J♦, giving him a double gutshot straight draw.”
