History of this tournament: This is a private tournament just for Romanian players. GGPoker gives you a ticket to a weekly $20 tournament if you deposit $20 into your account. This tournament is played every Sunday Night and has unlimited re-entry, but it is CAP at 5000 players, the GTD used to be $10 000 but since they give away $20 tickets, that GTD prize was always exceeded , so starting this year GGPoker made it $50 000 GTD, even like this the GTD is exceeded, so it's mad value to play this tournament, especially if they give you a ticket....like I do. 
The field is full with crazy people who do not know how to play, make crazy plays it's pretty much a lottery 
but if you play it for free is fun, and the top prize is at least $8000, so is mad value.
I only have history of 90 hands with the UTG and here are his stats: VPIP 27 PFR 12 Limp 18 Cold Call 12 3-bet 0 Post Flop AGG 2.60 Flop C-bet 57 * I do not see this stats on GGPoker platform
How would you play this hand?
