In the first study, DeDonno had 41 college students play eight games, totaling 200 hands, of Turbo Texas Hold'em, a computerized simulation of 10-player Hold'em poker. The game consists of being dealt two cards in the first round. The player must decide whether to play or quit based on the hand. If the person decides to play, then three cards are dealt for the community pot. Again, the player has to decide whether to play or stop. The player must also consider the betting patterns of the other players in making a decision in moving to the next round. If continuing, then the player sees another card and has to decide again to bet or lay down the cards. This is repeated until there are five cards on the table.
Overall most of the students had little experience playing poker, said DeDonno.
Half of the students in the first group were given charts that ranked the two-card combinations from best to the worst and also learned that professional poker players typically play about 15 percent of the hands dealt them. The other group was given background on the history of poker with no strategies.
He found that students given some strategies to make decisions did better than those without the strategies.
When starting the study, almost two-thirds of the students (64 percent) felt that winning at poker was 50 percent luck.
"If it had been pure luck in winning, then the strategies would not have made a difference for the two groups," said DeDonno.
