Who is BW?

On the main page in his article about sportsbooks acting like the cowardly lion, Buzz Daily states...

Casino customers who blow their bankrolls at the BJ tables and craps pits are accommodated with open arms to bet five and six figures. Just about anyone else is considered an agent of B.W. and gets the third degree, or is arbitrarily turned away.
Who or what is B.W.???
Billy Walters. Professional gambler, who is very successful at what he does. Worked in conjunction with the computer boys.

He's one of the main reason a line will move 1.5 pts. or more on a game.

I suggest you do a GOOGLE SEARCH, type in the name BILLY WALTERS, and you will get to know a lot more about this icon than has been posted thus far...
