What is roughly the number of hands that a player has to play during the tournament to reach the final table of the WSOP main event? Let us say over the past five years.
It depends a lot on the origin of the player. Chris moneymaker for example won the main event without having prior experience, so I would guess he played no more than 2500 hands (that's just a hard guess, I don't know Chris moneymaker more than that and he might easily have played more than that before)
A professional poker player on the Internet could have played 3 years 25000 hands a month, for a total of almost 1 million hands
