Slowplaying question

[saxhoe]

Do you ever slowplay when you have raised preflop and hit a good flop? I just wonder because I believe I never do that. Am I hurting my winrate a lot?

Example:
I have been playing pretty nitty on this table for a couple of orbits since I sat down. Villain seems LAP but pretty weak postflop.
Blinds: $0.50/$1
5 players
Converter

Stack sizes:
UTG: $150.67
Hero: $114.95
Button: $82.50
SB: $102.80
BB: $88.90

Pre-flop: (5 players) Hero is CO with Q[img]/images/graemlins/heart.gif[/img] Q[img]/images/graemlins/club.gif[/img]
UTG calls, <font color="#cc0000">Hero raises to $5</font>, 3 folds, UTG calls.

Flop: 2[img]/images/graemlins/diamond.gif[/img] 3[img]/images/graemlins/spade.gif[/img] Q[img]/images/graemlins/diamond.gif[/img] ($11.5, 2 players)
UTG checks, <font color="#cc0000">Hero bets $7</font>, UTG folds.
Uncalled bets: $7 returned to Hero.

Results:
Final pot: $11.5

Is this a "slowplayable" hand? What do you consider before you decide to slowplay?
