Third Hand is not obliged to take the dealer out of a spade, and should not do so unless he is a trick or two stronger than he would have to be to declare as dealer. But the dealer must never be left in with a two or three spade bid. If third hand cannot do any better, he should declare a royal. When the dealer bids no trump, third hand should take him out with any weak five card suit and nothing else, simply to warn him that there are no winning cards in the hand. Always take him out with five cards in a winning suit, no matter how strong the rest of the hand.
Take the dealer out of one suit with another suit only to deny his suit. Take him out of a winning suit with no trump, only to deny his suit and show strength in each of the three other suits. If the dealer bids no trump and second hand calls a suit, double if you can stop the suit twice, otherwise show any good suit of your own, but do not go two no-trumps unless you can do it all yourself. Leave that to your partner. Do not assist your partner’s suit bids with less than three tricks if second hand over-calls.
Fourth Hand bids on the bidding much more than on his cards. He should never take the dealer out of a spade that both second and third hand have passed unless he can go game. If the dealer bids a losing suit, second and third hands passing, leave him in unless you can go game and are not afraid of a shift. If the dealer bids a winning suit, second and third hands passing, make any sound declaration. If the dealer starts with no trumps, show any suit that might save the game if led at once by your partner.
Subsequent Bids. Any suit bid on the second round but not on the first, shows length without the tops. When a winning suit is taken out by the partner, a losing suit bid on the second round shows tops in it. Any suit rebid on the second round, without waiting for the partner’s assistance, shows six or seven sure tricks in hand.
Never bid a hand twice, unless its strength is greater than indicated by the first bid. Having bid a club on ace king alone, that is the end of it. If you have an outside ace, which the club bid did not show, you can assist your partner once on that trick, but no more. Having assisted your partner’s suit bid with three tricks, do not bid again unless you have a fourth trick in hand, but if he rebids his suit without waiting for you, you may assist on one trick, especially a high honour in trumps.
Do not double unless you have a certainty and are not afraid of a shift. Do not give up a fair chance for going game yourself just to double an adversary, unless you are sure of 200 in penalties at least, and do not give up the rubber game for less than 300. Always remember that a double may enable an adversary to go game, and will often show the declarer which hand to finesse against.
Free Doubles are opportunities to double when the declarer will go game anyhow if he makes his contract, but they should never be made if there is any chance that he may shift.
Free Bids are anything better than a spade by the dealer, or anything that over-calls a previous bid, because no one is forced to bid on the first round. A Shout is a bid that is a trick more than necessary to over-call the previous bid. It shows a solid suit, or five or six sure tricks in hand. In a losing suit it is a loud call for the partner to go no trumps if he can. A free bid in a losing suit shows the high cards; in a winning suit it shows the tricks in hand.
A Forced Bid is one that is necessary to over-call, such as two diamonds over a heart. This does not mean that the caller would have bid two diamonds originally. A player who must indicate a lead against a no-trumper makes a forced bid.
The Original Lead. The first card must be played before dummy’s hand is exposed.
