The Cigital, a Washington, DC-based consulting organization, conducted the first large-scale study of more than 100 million hands. Most experienced poker players would agree that the following are the two most significant results:
Three-quarters of all hands never go to showdown.
Approximately 12% of hands are won by the best hand.
According to estimates, between 80 and 85 percent of regulars in No-limit poker games at $1/$2 or $2/$4 stakes are losers in the long haul. The issue stems from the game's inherent variance ("luck"), as well as a variety of other elements. These include rake per hand and frequently a poor beat jackpot. Winning 1 or 2 BB/hour routinely under these conditions is unrealistic, even if you're reasonably experienced in cash games.
Mid-stakes and high stakes are where professionals appear. These stakes range from $2/$5 to $10/$20 going up, and ten to fifteen percent of regulars are long-term winners at these stakes.
