Used this once in a live game, it was a €50 buy in with 3 players left 11 entrants, winner take all game, big pot, but it was in a bar. The other two players were hopelessy drunk at this stage.
So the barman comes in and anounces that all the time we have left is for 2 more orbits, and that the chip leader at this stage wins (chips are average but i was sitting in 2nd), but while all this was going on i took a peek at my cards AA
So one of the other players asked if we just turn the cards and let luck decide the game OK SURE, not even a single spectator seen me look at the cards, I agreed and the other player declined, WHHHOOOO 500euro up.
But that was the only time ive ever done it. And im sure if i was caught in that particular game i would have promptly gotten a broken nose for my trouble.
