I believe that you should be able to show your cards whenever you want in any format. If poker is indeed a game of psychological warfare, than you should be able to use all the tools available that would help you gain any edge possible.

Has anyone ever heard of Phil Laak's "shower shuffle". He says it does not happen often maybe only once a year. But there will be a time when you hold the nut flush (not on a 4flush board) and you are sure your opponent holds a weaker flush. You then show your ace high flush card and move the rest of ur chips into hte pot. The thinking is that opponent wll not believe that you are moving in with the actual hand you are holding. Tactics like these just make the game more unpredictable and more fun to play.
