Sb check, BB, checks, Seat 2 checks, Villian bets 4, Hero calls?? (I wasnt really thinking of folding here, but it took me a long time to debate between raising or just calling here. Because I wasnt closing the action i just decided to call in fear that my raise would have people follow me in with a middle wrap and someone else with a FD)
SB folds, BB calls, Seat 2 folds
