DECLARER'S ADVERSARIES
The adversaries of the Declarer must realize that they are at some disadvantage in the play. The Declarer knows every card in the Dummy, but each of his opponents can at best only guess the holding of his partner. They should, therefore, strive by every means in their power to give each other all possible information.
They should always play the lowest, and (except with Ace, King, and one or more others) lead the highest of a sequence. The only case in which they should withhold information or play a false card is when such action may upset the calculations of the Declarer, and either cannot mislead the partner, or, if it do, will not affect his play. For example, with King, Queen, over an adverse Ace, Knave, 10, a false card is more than justified, as it tempts the Declarer to mould his play for another finesse; so also, in other cases in which the partner is without strength in the suit and his play is, therefore, unimportant, he may be treated as if he were a Dummy.
The advantage of forcing the strong hand is just as great in Auction as in Whist or Bridge, and as a rule it is the best play possible for the adversaries of the Declarer. The only exception is when the Dummy has an established suit and a reëntry.
Suppose, for example, with four tricks to play, the Declarer has the last Trump (Hearts), one Club, and two Diamonds. The Dummy has three winning Clubs, and the leader a Diamond and winning Spades. He knows he can force the Declarer's last Trump with a Spade, and generally this would be his wisest play; but the long Clubs in the Dummy show that the usual tactics cannot now be employed, and his only chance is to lead a Diamond hoping that his partner has one or two winners.
It goes without saying that leading a suit the weak adverse hand can trump, and upon which the strong hand can discard, is carrying out a custom most commendable at Christmas, but which at the card-table does not arouse the enthusiasm of the partner.
A player should
