Flopped the nut flush, when to slowplay?

[bsnone]

Not that interesting of a hand but wanted some feedback after todays session.

8/16 live kill game, the kill is on (16/32)

Killer is on the SB

Hero is in BB with A [img]/images/graemlins/heart.gif[/img] 2 [img]/images/graemlins/heart.gif[/img]

Calling station UTG calls, folded to tight cutoff who calls, I call, the killer checks his option ($64 preflop)

Flop: K [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/heart.gif[/img] 4 [img]/images/graemlins/heart.gif[/img]

SB Bets, hero calls, utg folds, cutoff folds. ($96)

Turn: 6 [img]/images/graemlins/spade.gif[/img]

SB checks, Hero bets, SB calls ($160)

SB Checks, hero bets, SB calls. Hero drags the pot.

My main question is how many of you raise this flop - I think if I raise on the turn i give way too much information away on my hand while potentially getting more money into the pot. I was suprised when no one behind me called the flop bet - I really expected utg to call one bet but it just didnt happen. I like to think that I have a tight agressive style but really my biggest strength is preflop play as I am really still learning how to optimize flop turn river play (learn something new every day)

Did I miss the flop bet or just get unlucky that no one called behind. Thanks everyone.
