And to win every hand you play past the first street, if you want to ignore the semantics, would still make even the tightest player I know a humongous winner. The reason playing overly tight players lose (which is generally not by much) is that even the average hand that they play is an underdog to win. Make 100% of even the biggest nit's flop hands hold up and yeah, he's the best poker player in the world.
