Pokerstars is a total scam. Read more about them online you will find hundreds of reviews.
Plus nobody ever saw their independent computer generator audit report.
Like the amount of time people will get AA, 33, 1010, for instance, and then A 3 6 10 6 on the table is not even funny.
No matter how good u r in a real game that bs comes up both in ring games and tournaments.
Thus, stay away from pokerstars.
