The levels may be an hour long, but the limits do increase quickly in the WSOP stud tournaments. With limits of 300 and 600, the current average stack is about 8,000 chips, or just over 13 big bets. That leads to quick eliminations.
People who have recently been eliminated include: Paul Darden; Doug Carli; "Miami" John Cernuto; Ali Eslami; Keith Sexton; and Allen Kessler.
