66 live 5-5 500 max buy in turn bet

[mike l.]

5-5 500 max buy in live game just okay game. i have around $500 and so do most of the players. i limp w/ red 66 after one limper, a bunch of guys limp, the button makes it $15, blinds call, i think about making it like $150 but just call, everyone calls. 7 of us. no big reads on anyone, except to say this is not an all-in every other hand sort of table, it's mostly younger guys trying to play tight and decent. i have done nothing they wouldve seen except raised a preflop raiser on the flop $200 once and folded when he put me all in.

the flop is 8s3s2c. sb checks, bb bets $20, folded to me and i call, 2 more players call including the button, and sb who looks like he's about 12 says "im pretty sure i have the best hand guys, i dont know why im just calling" before he calls.

the turn is 5h. checked to me and i bet $140.
