Tenace Positions. Many expert players will not lead away from a suit in which they hold tenace. Having two suits, one containing a tenace, and the other without it, they will select the latter, although it may be much weaker. It is noteworthy that players who disregard the value of holding a tenace in the opening lead, are well aware of its importance toward the end of the hand. When one player holds tenace over another, the end game often becomes a struggle to place the lead; and players frequently refuse to win tricks in order to avoid leading away from tenaces, or to compel another player to lead up to them.
Underplay is often resorted to by the Fourth Hand in suits in which the Third Hand has shown weakness. For instance: A small card is led; Third Hand playing the Ten, and Fourth Hand holding A Q J x. It is a common artifice to win with the Queen, and return the small card. When the original leader is underplayed in his own suit, he should invariably put up his best card.
Finessing. The expert may finesse much more freely than the beginner. Having led from such a suit as K J x x and partner having won with Ace and returned a small card, the Jack may be finessed with strong trumps. If the adversaries lead trumps, and the Ace wins the first round, a player holding the King second hand on the return, may finesse by holding it up, trusting his partner for the trick.
In all cases that mark the best of the suit against a player, and on his left, he may finesse against the third best being there also. For instance: A player leads from K 10 x x x. Third Hand plays Queen and returns a small card. The Ten should be finessed, regardless of trump strength, as the Ace must be on the left, and the finesse is against the Jack being there also. Many varieties of this finesse occur.
Placing the Lead. This is usually a feature of the end-game A player may have an established suit, his adversary being the only person with any small cards of it. If the lead can be placed in the hand of this adversary, he must eventually lead the losing cards.
A player begins with a weak suit of four cards, on the first round of which it is evident that his partner has no more, the adversaries having all the high cards. The suit is not played again, and for the last six tricks the original leader finds himself with three cards of it, and the Q x x of another suit. If the adversaries play King and Ace of the latter suit, the Queen should be given up, trusting partner for the Jack, for the Queen will force the holder of the three losing cards into the lead. It is sometimes necessary to throw away an Ace in order to avoid the lead at critical stages of the end-game.
False Cards. It requires more than ordinary skill to judge when a false card will do less harm to the partner than to the adversaries. There are some occasions for false-card play about which there is little question. Having a sequence in the adverse suit, the Second or Fourth Hand may win with the highest card, especially if the intention is to lead trumps. Holding K Q only, Second Hand may play the King, especially in trumps. Holding A K x, the Fourth Hand should play Ace on a Queen led by an American leader. With such a suit as K J 10 x, after trumps have been exhausted, the Ten is not a safe lead; Jack or fourth-best is better. Holding up the small cards of adverse suits is a common stratagem; and it is legitimate to use any system of false-carding in trumps if it will prevent the adversaries who have led them from counting them accurately.
Playing to the Score. The play must often be varied on account of the state of the score, either to save or win the game in the hand. If the adversaries appear to be very strong, and likely to go out on the deal, all conventionalities should be disregarded until the game is saved; finesses should be refused, and winning cards played Second Hand on the first round. If the adversaries are exhausting the trumps, it will often be judicious for a player to make what winning cards he has, regardless of all rules for leading, especially if they are sufficient to save the game.
It often happens that the same cards must be played in different ways according to the state of the score, and the number of tricks in front of the player. A simple example will best explain this. Hearts are trumps; you hold two small ones, two better being out against you, but whether in one hand or not you cannot tell. You have also two winning Spades, one smaller being still out. The game is seven-point whist. The importance of playing to the score will be evident if you consider your play in each of the following instances, your score being given first:
