Hero has Q

J

in the BB.
We're 6-handed at the moment.
Villain #1 (MP) has been playing loose passive. Her raising range is probably wider than AA-KK, but it's not like suited connectors or some junk.
Villain #2 (BTN) didn't realize MP raised and tried to pull his 1 bet back. But since SB had already called the 2, he was forced to put in 2 bets. I've seen him bet marginal hands when checked to.
Villain #3 (SB) is a typical nondescript 8/16 player. Shows aggression when he has a hand, calls if he thinks he has a chance to win, etc.
Anyway, preflop: MP opens, BTN and SB coldcall, I call.
Flop (7.5sb, 4ppl): T
