uch conditions, the Second Hand should declare a suit headed by King, Queen, Knave, or some similar combination, but should avoid bidding a long, weak suit, as the No-trump declarer may hold Ace, Queen of it, and the partner may, by the call, be invited to lead his King into the jaws of death. Of course, if the hand contain reëntries, it may be advisable to make such a bid, although even then it may advantageously be delayed until the second round, since against a two Spade declaration the Second Hand is sure of having another opportunity to speak.
With three Spades declared by the Dealer, the Second Hand expects a Royal from the Third Hand. He knows that he will have another chance to bid, but, as he will then probably have to go much higher, it is just as well not to wait if the hand contain any advantageous declaration.
WHEN TO BID NO-TRUMP OVER A SUIT
The question of what amount of strength warrants the Second Hand in bidding one No-trump, after a suit has been declared by the Dealer, is somewhat difficult to accurately answer. It goes without saying that to justify a No-trump under such circumstances, the Second Hand must have much better than merely an average holding. The suit that the Dealer has bid should be safely stopped, and when the declarer has only one trick in that suit, at least four other tricks should be in sight.
Occasionally cases arise in which the Second Hand may bid one No-trump over a suit declaration without the suit that has been declared being stopped, but these are rare and such a call should only be made with unusual strength, as it gives the partner the right to assume that the adverse suit is stopped and he may consequently advance the No-trump to dangerous figures.
It is probably a good rule that a No-trump should not be called over a declared suit, that suit not being stopped, with a holding of less than six sure tricks. Even with one stopper in the suit bid, it is generally better to declare either Royals or Hearts in preference to No-trum
