His study of more than a billion hands of online Texas Hold’em found that 85.2 percent of the hands were decided without a show of cards. In other words, players’ betting decisions were of overwhelming importance in determining the outcome. Of the remaining 14.8 percent, almost half were won by a player who didn't hold the best hand but instead had induced the player with the best hand to fold before the showdown.
Isn't inducing the player with the best hand to fold before showdown the same as a hand decided without a show of cards? Or do they mean that 85.2% of hands were decided without seeing the flop? Both don't sound right.
