The player's betting pattern was identified by the company's risk management as one that gives an advantage over other players' bets.

Can you provide some more information about the ways this player's bets gave them an advantage over the bets of other player's, so we can get a clearer picture of what happened? What you said doesn't make the situation clearer. It just scratches the surface a bit without getting to the point.
