The Official Encyclopedia of Bridge indicates the best line of play in contract bridge for a single suit in isolation in which declarer and dummy lack the ten but possess the ace, king, queen and jack. The line of play varies depending on how many cards are held by the defence, and the required minimum number of tricks. The probability of success is also shown.

The combinations considered by the Official Encyclopedia of Bridge (6th edition) are :

• Declarer and dummy hold six cards combined, 5 tricks required:
  • x - AKQJ9
