Its real name is Be Honest, What is It by Eddie Fechter.
Practice it in the dark or with your eyes closed. Maintain eye contact with the spectator. Keep all the attention on the card he is holding. It is quite easy to pull off - it just takes a split-second of misdirection. I have done this many times surrounded and no one has questioned me. Keep confidence in yourself in your ability to pull it off. If you are nervous and you show it, you will draw attention to the fact that you are going to pull a really gutsy move off. (it's not really that gutsy but...)
Keep the hand holding the switched card stationery after pulling off the move, while your other hand (holding the deck) moves forward, gesturing towards the card in the spectator's hand. It solves many angle problems, and it covers up the switch of the move.
