Louie started playing in tournaments at the World Series of Poker in the 1970s. He won four WSOP championship bracelets and also cashed in four events at the World Series, meaning that he ended up winning every tournament at the WSOP that he played in, when he made it to the money.
He is also credited as being the first player in the history of the WSOP to table a Royal Flush, which took place during the 1979 Main Event. Professional George Huber was the man on the losing end of the historic hand.
Louie won his first WSOP bracelet in the 1978 $5,000 Draw High event, winning $21,000. In 1979 he won two bracelets, one in $1,000 Ace to Five Draw and one in $2,000 Draw High. Louie won his fourth bracelet in 1980 in the $1,000 Razz event. His total tournament winnings at the World Series of Poker exceed $100,000.
