Suit combination - J missing

From Wikipedia, the free encyclopedia

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 jack but possess the ace, king, queen and ten. 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 play recommended by the encyclopedia is generally to finesse the 10 or play off the top honors depending on the precise combination as shown below:
x - AKQT: finesse
x - AKQTx: finesse
x - AKQTxx: drop off
x - AKQTxxx: drop off
