2334: 2-3-3-4, by itself, scores 8 in a hand of cribbage, but provides fertile ground for more points with the help of the turn-up card. A six, eight, nine, ten or a royal card will automatically increase the 8 to 12 with fifteen-two, fifteen-four. Either of the outside cards in the run - 2 or 4 - will double the score to 16, and a third three as the turn-up card will score you a respectable total of 17 - six for the threes, three runs of three, and fifteen-two from 2-3-3-3-4. A turn-up five will also give you 12 points for a double run of four, a pair, and fifteen-two. Even the most unhelpful turn-up of an ace or a seven will give you ten points, either by extending the double run or scoring fifteen-two (7-3-3-2). (otyikondo)
