You have a standard deck of 52 playing cards well-shuffled on a table face down. You flip over cards one by one, hoping to reveal an Ace. You can stop at any time before revealing an Ace and keep the last card you flipped. If you reveal an Ace, you lose and the game ends. What strategy maximizes your probability of stopping on a card that is an Ace (i.e., successfully drawing an Ace without ever flipping one earlier)?
