Dealer is expecting to take four tricks with his own hand, and if the Dummy take three (one-third of the remaining nine), he will fulfil his contract. Even if the Dummy fail to render the amount of aid the doctrine of chances makes probable, the declaration is not likely to prove disastrous, as one No-trump is rarely doubled.
It is also conventional to declare one No-trump with a five-card or longer Club or Diamond suit,[2] headed by Ace, King, Queen, and one other Ace. This is the only hand containing strength in but two suits with which a No-trump should be called.
As a rule a combination of high cards massed into two suits does not produce a No-trumper, although the same cards, divided into three suits, may do so. For example, a hand containing Ace, Queen, Knave, in one suit; King, Queen, Knave, in another, and the two remaining suits unguarded, should not be bid No-trump, although the high cards are stronger than the example given above with strength in three suits.
Admitting all the advantage of the original No-trump, even the boldest bidders do not consider it a sound declaration with two defenseless suits, unless one of the strong suits be established and the other headed by an Ace. The reason for this is easily understood. When the adversaries have a long suit of which they have all the high cards, the chances are that it will be opened; but if not, it will soon be found unless the Declarer can at once run a suit of considerable length. When a suit is established by the adversaries, the Declarer is put in an embarrassing position, and would probably have been better off playing a Trump declaration. It is a reasonable risk to trust the partner to stop one suit, but it is being much too sanguine to expect him to protect two. Should he fail to have either stopped, the Declarer's loss is so heavy that only with a long and apparently established suit and an additional Ace is the risk justified. It is realized that the case cited, namely, Ace, King, Queen, and two others, may not prove to be an established (or solid, as it is often called) suit. If however, the division be at all even, as it is in the vast majority of cases, the suit can be run, and it is cited as the minimum holding which may be treated as established.
With the present value of Clubs and Diamonds, either suit presents an effective original declaration. There is, therefore, much less excuse than formerly for a reckless No-trump bid, based upon five or six Club or Diamond tricks and one other suit stopped. When, however, an Ace of another suit accompanies the unusual Club or Diamond strength, the advantage of being the first to bid No-trump makes the chance worth taking.
The hands above cited as containing the minimum strength to warrant the call are all what are known as "weak No-trumpers." This kind of bidding may not be conservative, but experience has shown it to be effective as long as it is kept within the specified limits. A No-trump must, however, justify the partner in acting upon the assumption that the bidder has at least the stipulated strength, and it merely courts disaster to venture such a declaration with less than the conventional holding.
A few examples may possibly make the above somewhat more clear, as by that means the various "minimum-strength" or "border-line" No-trumpers, and also hands which fall just below the mark, can be accurately shown. It will be understood that an effort is made to give the weakest hands which justify the No-trump declaration, and also the hands which fall short by the smallest possible margin. In other words, the hands which puzzle the Declarer. With greater strength or greater weakness the correct bid is plainly indicated.
The suits are numbered, not designated by their respective names, in order to emphasize that it does not matter where the weakness is located.
HANDS IN WHICH THE NO-TRUMP DECLARATION IS DOUBTFUL
Suit 1 | King, Knave, X | Does not contain an Ace, but is above the average and has four suits stopped. It is a No-trump bid. |
Suit 2 | King, X, X | |
Suit 3 | Queen, Knave, X | |
Suit 4 | Knave, Ten, X, X | |
Suit 1 | Ace, Knave, X | Has an Ace, three suits stopped, and a Knave over the average. It is a No-trump bid. |
Suit 2 | X, X, X | |
Suit 3 | King, X, X, X | |
Suit 4 | Queen, Knave, X | |
Suit 1 | Ace, Queen, X | Has an Ace and two face cards more than the average, but, not having three suits stopped, is not a No-trump bid. |
Suit 2 | King, Queen, Knave | |
Suit 3 | X, X, X, X | |
Suit 4 | Knave, X, X | |
Suit 1 | King, Queen, X | Has three suits stopped, but is without an Ace, and is one King short of three King suits all with another face card. It is not a No-trump bid. |
Suit 2 | King, Knave, X, X | |
Suit 3 | Queen, Knave, X | |
Suit 4 | X, X, X | |
Suit 1 | King, Knave, X | Has three King-Queen, King-Knave suits. It is a No-trumpor bid. |
Suit 2 | King, Queen, X | |
Suit 3 | King, Knave, X | |
Suit 4 | X, X, X, X | |
Suit 1 | Ace, X, X | Has three suits stopped and is above the average. It is a No-trump bid. |
Suit 2 | Ace, X, X, X | |
Suit 3 | Queen, Knave, X | |
Suit 4 | X, X, X | |
Suit 1 | Ace, X, X | This is the border-line hand mentioned above. It may be a No-trump bid for an expert, but the moderate player is hardly justified in risking it. The presence of one or two Tens would add materially to the strength of this hand and make it a No-trump. |
Suit 2 | King, X, X | |
Suit 3 | X, X, X, X | |
Suit 4 | King, Knave, X | |
Suit 1 | Ace, X, X, X | Only above the average to the extent of a Queen in place of a Knave. No-trump is not advised unless Declarer is confident he can outplay his adversaries. |
Suit 2 | King, Queen, X | |
Suit 3 | Queen, X, X, X | |
Suit 4 | X, X | |
Suit 1 | Ace, Knave, X | An average hand. With this holding only an expert is justified in bidding No-trump. |

Suit 3 | Queen, X, X, X | |
Suit 4 | X, X, X | |
Suit 1 | Ace, X, X | Below the average, and, |
