I been playing this game for 50+ years live and about 15 years or so on line, and I know grift when I see it.
Certain players are wining at very high rates regardless of their held hands, I'm going to explain how they do it and if not disallowed I will tell you who a few of the grifters are so you can see what I explain first hand.
If their are rules about naming screen names, stop me now.
