Suit combinations - J missing

From Wikipedia, the free encyclopedia

See main article Suit combinations. Tables presented below indicate 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, ten and queen. The required minimum number of tricks is indicated as well as the probability of success (POS). The line of play that is optimal in matchpoint scoring (the line of play that beats other lines of play on as many lay-outs as possible) is marked with (MP). Best defense is assumed (including falsecarding where necessary). In all cases it is assumed declarer and dummy have enough entries via the orther suits. In the lay-out for declarer and dummy, irrelevant small cards are denoted by 'x', and the ten is denoted by 'T'. In the descriptions 'RHO' stands for 'right hand opponent' (the opponent sitting behind dummy), and 'LHO' stands for 'left hand opponent' (the opponent sitting behind declarer).
