It is widely believed that Amarillo Slim was the best gambler of all time, not just because of his poker skills but also his creative prop bets.
Thomas Austin Preston Jr., or Amarillo Slim, won the WSOP Main Event in 1972 for $80,000. He was also among the players who invented Texas Hold’em.
In 1979, he founded Amarillo Slim’s Super Bowl of Poker, the tournament series. Finally, in 1992, Slim became a vital part of the Poker Hall of Fame.
When talking about Amarillo Slim, his net worth was an estimated $1–5 million before his death. Certainly not close to being one of the richest gamblers around, but bear in mind the pros made a lot less money back in his day.
