PLAY FOR AN EVEN BREAK
The Declarer, in the absence of any positive indication to the contrary, should base his play upon the probability of an even division of the cards. That is, with seven of a suit in his own hand and Dummy, he should play for each of the adversaries to have three; with nine, he should play on the basis that the four missing cards are equally divided. In the long run, playing for the even break will net many tricks, but in a small percentage of instances it will result unfortunately. The case in which the question most frequently arises is when either in Trumps or in the Declarer's strong suit in a No-trump, the two hands hold nine cards headed by Ace, King, Knave. The division between the two hands may be
| Ace, King, Knave, X, X | and | X, X, X, X |
| Ace, King, X, X, X | and | Knave, Ten, X, X |
| Ace, Knave, X, X, X | and | King, X, X, X |
| King, Knave, X, X, X | and | Ace, X, X, X |
| or any other. |
In all these cases the Knave finesse is tempting, but it should be refused, and the Ace and King played with the expectation of an even break which will drop the Queen on the second round. The exceptions to this general rule occur when
(a) The presence of the Queen in either adverse hand has been indicated by some declaration or double.
(b) When one adversary has shown unusual length in some other suit.
In the latter case, it is sometimes wise to play on the assumption that the adversary, very long in another suit, has but one of the suit in question, and consequently to finesse the second round on that basis.
GENERAL PLAY OF THE DECLARER
The Declarer, as soon as the Dummy's cards are spread, should size up the situation, see how many tricks are in sight, what suit or suits it is necessary for him to establish, and what, if any, finesse or finesses he will have to make in order to secure his declaration and his game.
In determining which way to finesse, he should be materially assisted by the bids of his adversaries, and during the play, as situations develop either in his favor or against him, he should be continually figuring on the best method to make his declaration. He should remember that failure to fulfil his contract will not only result in a material loss on the score, but, in the end, may cost the rubber. When the scheme of play he has planned at the start shows signs of becoming unsuccessful, he should, if possible, change it for one more promising.
