FLOP: 4 8 J
Hero bets $800, BB bets $5,060 and is all-in, Hero ?


Tough spot for me, i highly doubt he hit the J, but can i call? as usual i have agressive late game image and everyone is in resteal mode so i have tough time getting folds, easy when i am empty but in such cases im puzzled.
Opponent has got pretty agressive and doesn't play very good.
