Oh my god I'm going to win a pot

[HOWMANY]

Pretty tough 60 game at Commerce. Someone raises UTG, 3 coldcalls, I call with 66 in the CO, button calls, blinds call. 8 to the flop. Villain in this hand is the button who is John, the laggy white dude with shaved head and some tattoos. Other guy in the hand is Sam the laggy Russian guy but he's not really that important because if he's not jamming the pot himself his hand sucks.

I'm a superstar. Check to me I bet, John raises, fold to Sam who calls 2, fold to me I 3bet, John caps.

Raising the flop here with a flush draw is obviously a bad play but there's also 0% chance he caps an 8 here so he has 88/flush draw here and I'd assume he'd call with 88.

Sam checks, I should try to bet/3 or c/r?
