I'm a trickster cheater. When I cheat, I'm extremely obvious and usually very upfront about it.
I have been known, to stack the deck BUT only in cases when I am on the losing end of an embarrassingly bad game of let's say Cribbage or Gin Rummy. My poor husband. It has taken him years to figure out never to leave the cards in my possession when he goes to the restroom. One of the best scoring hands in Cribbage is 29. It's hard to stack this hand but not impossible especially if he's gone for awhile (if you know what I mean). I almost got away with it once but could not contain myself. He was so impressed with my cards that my facial contortions and giggling gave me away eventually. I'm a good liar but not that good.
