nut flush, how to play it

Was playin on FT. They dont have a HH so ill have to Type it out for you guys.

6 max, $1/2 blinds
Just sat down at table with $200, both SB and BB have me covered

Dealt to Me on Button
:Ad: :9d:

Preflop action
3 folds, Button calls, SB completes, BB checks

Flop
:Jc: :7d: :6d:

SB checks, BB bets $6, Button calls $6, SB calls $6

Turn
:4d:
SB bets $10, BB calls $10 ...

now the question is... do i just call or raise? do you put either one of these guys on a set and worry about the board pairing or just slowplay it?

I decided to raise to $35 and BOTH players still call me. so im figuring one of them atleast for a set.

River
:3c:

SB checks, BB checks, Button bets $35 and both players call.

SB shows :8d: :3d: (8 high flush)
BB shows :Jh: :4s: (two pair)

now... if i hadnt of raised the turn i think i could have got the SB to go all in on the river. Was i giving these guys too much credit for hitting a set? Even though the BB could have filled up he only had 4 outs. I feel like i could have extracted a whole lot more money.

Flushes can be difficult to get much money from. Usually I play every hand hard so I would have raised the flush on the turn as well and hoped that someone had something worth paying me off with. Too bad the SB didnt have a better flush.

If you would have slowplayed the turn, I think it would have just kept the pot smaller. Neither one of these guys really looks like they were very attached to their hands. The board really sucked for the guy with two pair, so its lucky he even called that, and the smaller flush was scared so I dont think much money was ever destined to change hands with this hand.

Its possible that slowplaying the turn and then betting hard on the river would have gotten him thinking you had the straight, but I still dont see the pot getting huge.
