Sharps are:
#1 Know something about the wager Before the line comes out, weather, injuries, attitudes of players.
#2 They Always getting the BEST of the number, and bookmakers just hate that, no matter if it wins or not. They, the bookmaker got beat to the number!
#3 Sharps are people that bet enough to make a difference in the bookmakers opinion. Sometimes Not the limit but more than the public.
#4 They most usually play to the opener and anything other than that is just not them, unless its a "buy back" proposition, as it would come 1 moment before post time as not allowing the others to have time to get off.
#5 Groups that are sharp and Big enough will take the lead with a number, hopeing and thinking the public and others will follow and drive the number to a more advantageous position before the same group will buy back ALL of thier money and much more as it was the Wrong side to begin with.
#6 Billy Walters and crew are the Sharpest of ALL times.
#7 There are "other" groups out there today that try to be just like Walters and that bunch, but sometimes they are not.
#8 Wlaters and the "movers" that he has can bet more money than ANY shop can withstand over a course of time.
#9 Walters MUST have "movers" "beards" to be able to operate at the level that he likes to play.
I am sure there is more, i just cant think of it at this time. Besides i am not sharp enough to know more.
