Context

“Not merely do you hide your tactics, but you do your best to make others believe that you are on the brink of ruin as soon as you are sure of winning the game. In short, you dissemble, do you not? You lie to win four or five louis d'or. What would you think of a player so generous as to proclaim that he held a hand full of trumps? Very well; the ambitious man who carries virtue's precepts into the arena when his antagonists have left them behind is behaving like a child. Old men of the world might say to him, as card-players would say to the man who declines to take advantage of his trumps, 'Monsieur, you ought not to play at bouillotte.' "Did you make the rules of the game of ambition?” source
