I.—Where players agree "not to play spades" the rule is, that if the spade make is not doubled, the hand shall be played where either side is 20 or over.
II.—If the third hand player ask, "Shall I play?" or should he lead out of turn, or should the eldest hand lead without asking permission to play, the spade maker may take two on the score or may call a lead and require the hand to be played out.
III.—Should the third hand player double before his partner asks permission to play, the spade maker may decide whether the double shall stand or not; but the hand must be played out.
ETIQUETTE
It has been truthfully said that there is no game in which slight intimations can convey so much information as that of Bridge. In justice to those who, by their manner, give information, it may be stated that most of the apparent unfairness at the Bridge table is unintentional. Hesitation and mannerisms, however, cannot be too carefully avoided; such a breach of etiquette is an offence for which the adversaries have no redress except perhaps a refusal to continue the play.
It is obviously a greater fault to take advantage of information thus given. A play in your judgment may be perfectly sound, but you leave yourself open to criticism if it is in any way contingent on information obtained from your partner's manner.
Cultivate uniformity in your style of play; let there be no remarkable haste or hesitation in making or passing; try always to use the same formula of words, and do not call attention to the score after the cards have been dealt.
