Capped Small Four Flush on the Flop

[why4duck]

Playing live 8-16 at Casino Arizona.

I'm new to the forum. I've mostly played live at Arizona and Las Vegas casinos for the last couple of years, w/ some low/micro-limit online experience. I mostly play 4-8 and 6-12 hold 'em at Casino Arizona, occasionally playing 8-16 when there's a good table going.

I was only on the table for about 30 hands, so not a lot in the reads department. UTG is kinda tricky...caught me w/ KQx after he smooth called preflop w/ QQ and flopped a set. Both early position players seemed kind of passive, MP is fairly tight and aggressive...50/50 that he'll raise if he's coming in, and if he's raised preflop he will always fire/raise on the flop. SB got lost on the way to the slots.
