SPADE CONVENTION
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.
