DOUBLING
With any kind of fair strength the novice at Bridge is invariably anxious to double; but a few experiences with an adversary glad to embrace the opportunity to redouble, will turn the course of his anxiety to a desire to conceal such strength as he may hold.
Ordinarily be satisfied to win at all on the opponent’s make. By doubling you not only place the strength and thus enable the dealer to finesse successfully, but your double is a warning to the dealer to be cautious in leading trumps, and therefore, lessens your chances of winning tricks.
To increase safely the value of the tricks it is essential that you consider the state of the score, the possibility of a redouble, and your position in regard to the maker.
The score is a most important factor, and even, at times, justifies a double with only a fair hand. For instance, suppose the odd trick wins the game for your adversaries, and does not win it for you; if you double and secure the odd trick, the additional count may enable you to win the game on that deal or the next.
It is bad play to double when you need only an odd trick to win the game. If you double you lessen your chance of winning the trick, and by opening the way to a redouble perhaps give the adversaries the game.
Doubling on the rubber game is dangerous. The increased value of the tricks may enable your adversaries to win the rubber on that hand, when, otherwise, you might go out on the next deal.
Your position in regard to the maker claims equal consideration. If the trump has been made at your right, you play after the strong hand, and are, therefore, in a good position to make your high trump cards; but, if you double when this arrangement is reversed, and the maker is over you, the dealer has this advantage.
As spades are made for safety, occasions for doubling the spade declaration obviously arise more frequently than any other; yet players are prone to go to extremes in doubling spade hands, for, while it does not require much strength to double a defensive spade declaration, there is always a possibility of great trump strength in the adversaries’ hands.
Do not double the make of hearts, diamonds, or clubs without some strength in the trump suit; as high cards, particularly if the suits are long, may be trumped, strength in the side suits alone is unreliable. Spades, however, may be doubled with but little strength in the trump suit.
Be particularly conservative in doubling a “no-trump” make; for but rarely does it pay to double with a hand containing general strength. Remember that while you are in the dark as to your partner’s hand, the dealer has the enormous advantage of seeing and combining his own hand and the dummy; that he knows what suit to avoid, and what suit to establish; and that your doubling will place him in a still more advantageous position by enabling him to locate honours and make successful finesses. Be cautious, also, when you hold fair strength in three suits and are weak in the remaining one. The maker is apt to hold a very long suit and you will not find it easy to discard, and at the same time protect your hand.
Usually it is not safe to double a “no-trump” make unless you hold a suit that you are reasonably sure is established. It is a gamble to double with a six-card suit headed by ace, king, and queen with no other trick in the hand. You depend on your partner to take one trick, which he may not be able to do; and, should you find your long suit protected in the adversaries’ hands, you run the risk of being very badly beaten. If the odd trick wins the game for the adversaries and does not win it for you, such a double may be justifiable; still you cannot hope to win more than 24 points by doubling, and you risk losing three or four odd tricks with a possibility of a redouble. While such a double will often succeed it can hardly be classed as sound.
As the younger hand, it may be wise to double a “no-trump” make in order to prevent great loss or to save the game. In other words, it may pay to show your partner by a double that you have strength in a particular suit. There are at present two methods used by Bridge players to indicate this strength, one known as the Heart Convention and the other as the Weak Suit Convention.
