Not that I like the tone of OP who is accusing you of withholding his winnings because attacking everyone and everything around makes him look guilty. But for the sake of clarification, what kind of abnormalities are you talking about? What did the player do? What is a "Member professional betting style"? Do you have reasons to believe OP is part of an illegal betting crew or that he has insider information or something?
