[LuparFiend]

Villain is a total unknown. I have no datamined stats on him, so he is not a regular. This is only the 3rd hand at the table.

Flop: ($21) (2 Players)
UTG checks, Hero bets $12.00, UTG calls $12.00

UTG checks, Hero bets $30.00, UTG calls $30.00

River: ($105) (2 Players)
UTG bets $116.00, Hero ?????


Do I call this? He could have the flush obviously, but he could also have a busted draw (High heart plus a pair maybe?), two pair, etc...

edit: Now that I am looking at this, not sure why I bet so small on the flop. That is wierd. ignore that though and let me know what I should do on the river
