An interesting read produced by two professor from University of Chicago about knowledge and luck factors in poker.
Abstract:
In determining the legality of online poker – a multibillion dollar industry -- courts have relied
heavily on the issue of whether or not poker is a game of skill. Using newly available data, we
analyze that question by examining the performance in the 2010 World Series of Poker of a
group of poker players identified as being highly skilled prior to the start of the events. Those
players identified a priori as being highly skilled achieved an average return on investment of
over 30 percent, compared to a -15 percent for all other players. This large gap in returns is
strong evidence in support of the idea that poker is a game of skill.
