Line check: 3/6NL: Nut flush draw semibluff

[HoldEmKillah]

I haven't been here very long...maybe 15 hands or so. No read since I've been busy loading up GT, PT, searching for tables, etc (yeah, I know [img]/images/graemlins/tongue.gif[/img]). Anyway...

Party Poker No-Limit Hold'em, $6 BB (6 max, 3 handed) converter

saw flop|<font color="#C00000">saw showdown</font>

Hero ($595.40)
Button ($393)
SB ($699.20)

Preflop: Hero is BB with T[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/spade.gif[/img].
Button calls $6, SB completes, Hero checks.

Flop: ($18) 6[img]/images/graemlins/club.gif[/img], Q[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(3 players)</font>
SB checks, <font color="#CC3333">Hero bets $17</font>, <font color="#CC3333">Button raises to $34</font>, SB folds, Hero calls $17.

I thought about 3betting here but I hate miniraises and I don't think I'd have much FE against top pair given it's 3handed and I've been playing aggressively. Besides, tons of bluff cards can hit. Sound logic? Or 3bet?

Turn: ($86) K[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">Button bets $30</font>, <font color="#CC3333">Hero raises to $175</font>, Button calls $145.

How's my turn line?

Is this a check/call to snap off a bluff or push? Villain has about $175 behind.
