Studying blackjack on the 701

In 1954, a team of scientists ran millions of simulated hands of blackjack on an IBM 701 in an attempt to determine the best playing decision for every combination of cards. The result of this study was one set of correct rules for hitting, standing, doubling or splitting in a blackjack game. These rules are still the same today.
