Answers.Body: <p>I can think of two questions you might be meaning to ask, given the wording of your question. Maybe neither of these is what you're after, but just in case:</p>
  
  <p><strong>1. Is it possible to castle out of check or even checkmate?</strong> Here the answer is <em>no</em>. If your king is in check, then castling is not a legal move.</p>
  
  <p><strong>2. Is it possible to castle while checkmating your opponent?</strong> Here the answer is <em>yes</em>, it is possible, though it does not happen often. For instance, the game <a href="http://www.chessgames.com/perl/chessgame?gid=1259009">Ed.Lasker-Thomas (1912)</a>, with its famous queen sacrifice and king hunt, could have finished with a castling mate:</p>
