Title: The role of skill versus luck in poker
Description: "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"--National Bureau of Economic Research web site.
