Select the lucky and avoid the unlucky. Bad luck is generally the penalty of folly and for the unfortunate there is no disease so contagious. Never open the door to a lesser evil, for other and greater ones will 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 the suit of the wise and prudent—sooner or later they will win the odd trick.
