When the Dealer has made an offensive declaration, the Second Hand must bear in mind that it is possible this may be his last opportunity to declare. A declaration under such circumstances being what is very properly termed "forced," is of a totally different character from the "free" declaration heretofore considered, and is not limited by any hard-and-fast rules as to the presence of certain cards. For example, should the Dealer bid one Royal, and the Second Hand hold seven Hearts, headed by Queen, Knave, he obviously must declare two Hearts; otherwise, even if the Fourth Hand hold the Ace and King of Hearts, and other strength, the declaration of one Royal might stand.
The principle is that an offensive bid having been made, the declaration of the player following does not of necessity show high cards, but does suggest the ability of the Declarer to successfully carry out the proposed contract.
When the Dealer has called a No-trump, the Second Hand is obliged either to pass, or declare two of some suit, or of No-trump. He must remember that against the Dealer's No-trump he is the leader, and as the information regarding his strong suit will be given to his partner by the first card played, it is not important that he convey it by a bid.
The No-trump may be only of minimum strength, but it may, on the other hand, be of much more than average calibre. The Third Hand has yet to be heard from, and if, as is possible, he have considerable strength in the suit that the Second Hand thinks of declaring, such a bid will offer an ideal opportunity for a profitable double. The Second Hand, therefore, should be somewhat diffident about bidding two in a suit. He should make the declaration only when his hand is so strong that in spite of the No-trump, there seems to be a good chance of scoring game, or he has reason to think he can force and defeat an adverse two No-trumps, or the No-trump bidder is a player who considers it the part of weakness to allow his declaration to be easily taken away, and can, therefore, be forced to dangerous heights.
This is an opportunity for the Second Hand to use all his judgment. The Dealer may be taking desperate chances with a weak No-trumper, and the balance of strength may be with his partner and himself, in which case it is important for him now to show his colors; yet he must always keep in mind that conservatism, in the long run, is the main factor of Auction success. It is the ability (possibly "instinct" is the proper term) to act wisely in such cases that makes a bidder seem inspired.
With a strong Club or Diamond holding and a reëntry, such a hand as, for example,—
| Spades | Two small |
| Hearts | Two small |
| Diamonds | King, Queen, Knave, and two small |
| Clubs | Ace, Knave, Ten, Nine |
it is generally unwise to bid Second Hand over one No-trump.
There is little danger of the adversaries going game in No-trumps, but they may easily do so in Hearts or Royals. A Second Hand declaration in this position may point out to the opponents their safest route to game, and is not apt to prove of material benefit, as with such hand, eleven tricks against a No-trump is extremely improbable.
A similar principle presents itself when the holding is five of any suit, headed by the four top honors, or even by the three top honors, and no other strength. With such cards, the No-trump can almost certainly be kept from going game, and if the partner be able to assist, the declaration may be defeated. If, however, two of that suit be called, the adversaries, not having it stopped, will not advance the No-trump, but if sufficiently strong, will declare some other suit in which they may score game.
