Suit combination – K10 missing

Main article: Suit combination

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 king and ten but possess the ace, 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) include holdings of 5, 6, 7, 8, 9, 10 and 11 cards by declarerer and dummy; allow for the loss of no tricks or one (more in a few combinations); give the percentage chance of achieving the target number of tricks; and shows the average tricks per deal. The line of play recommended by the Official Encyclopedia of Bridge varies from finessing the nine or the queen to playing for the drop of the king.
