It is perfectly fair for players to use the above-described, or any other convention, provided their adversaries understand its meaning. Conventions are an essential part of Auction. The lead of a King to show the Ace is a convention—so is every informatory play or declaration. When plays or bids are generally understood, it is unnecessary for players to explain their significance, but the adversaries should have all the information upon the subject possessed by the partner, and nothing approaching a private understanding should exist.

Query

The Dealer bids one No-trump, holding

Spades Ace, Queen, Ten, and three small
Hearts Ace, Queen
Diamonds Ace, and one small
Clubs Ace, and two small

Second and Third Hands pass; Fourth Hand, two Diamonds.

What should the Dealer declare on the second round?

Answer

Two Royals. The hand is far too strong to pass, while to bid two No-trumps is foolish, as, unless the partner hold the King of Spades, it is almost certain that the contract cannot be fulfilled.

Two Royals is safe and presents a good chance of game. A game in Royals is far more valuable than 100 for Aces, which may be reduced, if not wiped out, by penalties for under-tricks.
