I might try for a check-raise on the flop depending on the table but I think a bet is standard flop and turn. The river merits a bet, these guys are all very passive and with 3 of them I might get a lot of value when I'm winning. I have to call a raise because the pot is just so big, but it's only one lost bet and only when one of these calling stations is willing to raise. I don't see 4 being a common holding and a Q seems very unlikely to raise.
