how I raised my chess rating dramatically increases (over 21)

  Sometimes we all get a little tense or stressed, or even on edge when we play chess.  I found a cold beer or two seems to enhance by comeback agility in chess.  Next thing I'm mellow and checkmate.  I sip the final suds down and stumble into bed.  Checkmate I say, checkmate, I'll wake up tomorrow to a hangover and a new day of chess.
