David Shepherd:
   A most common error among cricketers today is to confuse the
   no-shot(played-at) clause. The no-shot clause ONLY applies to 
   balls which impact OUTSIDE OFF stump. Otherwise the shot is
   irrelevant.

   Whether the ball pitches outside off-stump does not change anything. 
   It's the point of impact that counts.   And of course ball pitching or 
   impacting outside leg-stump is  not out
