i think the CR size is too small as well, but for a different reason. it seems like you just want to get more money into the pot, and lets the table know that you are sitting on a nice hand, most likely a set or top two pair. this should scare the guy holding TP, and the guy holding the flush draw. Now, if you bet out on the flop, TP will call, and so will flush draw, but they cant put you on anything more than a pair. in fact, TP or flush draw may even raise you, which is good because then you can check-call or check-raise the turn to get an even bigger pot. but, as it stands, it looks like you just made a boat, and the flush isnt going to call here.

as played, a check on the turn might look like you are scared of the flush, or it might look like a made flush. a bet just scares away TP. let him bet into you, or bet the river for him if he checks behind. at least that gives him one more card to hopefully improve his hand.
