I took some time to play the whole month of December and try to rank high. The problem is there are some folks who will grind three or four games per day. You have to resist the crazy betting in the first 15 minutes and than start to build up your stack. To do well in the overall standing you need to keep getting in the top 1000 per game and than hit some hot streaks (top300). You can do well but it takes alot of time and patience.
