Select the Lucky and avoid the Unlucky. Ill-luck is generally the penalty of folly, and there is no disease so contagious to those who share in it. Never open the door to a lesser evil, for other and greater ones invariably slink in after it. The greatest skill at cards is to know when to discard; the smallest of current trumps is worth more than the ace of trumps of the last game. When in doubt, follow thesuit of the wise and prudent; sooner or later they will win the odd trick.
