It's been confirmed in the past. They have the exact same writing style, and their picks are always the same.
There is no such person as Bob Valentino. Bob Valentino doesn't do TV, Radio, or ever have a video.
Bob Valentino is supposedly a great blackjack and poker player yet he's not known around Vegas at all or have any poker cashes lifetime.
Same thing with Karl Garrett, who is Trace Adams. And Scott Delaney who is Chris Jordan.
Adams accidentally was calling Garrett's play a 2500 star last weekend, when Garrett only operates with 5 through 100 dimers. It's Adams himself who does the star plays.
Now I just have to find out who Tony Weston, Drew Gordon, and Michael Cannon is.
Basically if they don't have videos or do TV/Radio like Craig Davis they are fake and a scam marketing tool.
