Recently I was checking DZone for some interesting programming articles. One of the front page articles stated: Design Patterns Are Not Blueprints. If you haven't read it already, do it now.
Why wouldn't the pattern help? Because the author's case wasn't one we need a strategy for; he didn't need algorithm interchangeability or algorithm-caller separation. We'd be messing with a list of strategies instead of some simple code. (Worst case, he could have really messed himself up with softcoding and externalized the list of strategies to a configuration file. Good for him that he didn't do that!) So you should use the pattern only if it fits your case, not in every similar case.
