This is a gambling game inspired by "acey deucey", also known as "Red Dog" or "yablon".
Run the game, look at the hand and enter a bet (minimum 20) based on whether the hidden card will be between the two exposed cards.
When a good hand comes out (cards are far apart), take advantage of the odds and make a large bet. When a bad hand comes out (cards are close together), make a small bet and move on.
