Games are of course lost by bad moves but these arise in different ways.- Black loses this week's gamo because he lacks the courage of his convictions: he plays for a queen's side attack—and when the time comes he is afraid to make it. White on the other hand goes all out for his attack—perhaps recklessly—and one feels that, sound or not, justice has been done when he wins.
