Someone has kidnapped you and forced you to play a game of Russian Roulette ! Your kidnapper loads two bullets into adjacent chambers of an otherwise empty cylinder, and then spins the cylinder.
Then he presses the trigger ! Click ! Thankfully, the chamber was empty (this time!).
He then offers you a gamble : If you can survive the next round, he would set you free. To make it even better for you, he gives you two choices : One, he would spin the cylinder (randomly) before firing ; Two, he would just press the trigger now, without spinning.
Assuming that you would want to live through this encounter, what choice would you take? To spin or not to spin ?
