QQ faces preflop heat OOP and flop comes safe... against unknown

[zach383z]

Villan is unknown, this is about my 3rd hand at the table, I really dont know what to do here against an Unknown?

PokerStars No-Limit Hold'em, $0.25 BB (6 handed) Hand History converter (http://www.learnhowtoplaypokerfree.com/convert/convert.cgi) Courtesy of PokerZion.com (http://PokerZion.com)

BB ($25.80)
UTG ($26.95)
MP ($22.25)
Hero ($28.20)
Button ($32.70)
SB ($24.75)

Preflop: Hero is CO with Q/images/graemlins/diamond.gif, Q/images/graemlins/heart.gif.
<font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises to $1</font>, <font color="#CC3333">Button raises to $3</font>, <font color="#666666">1 fold</font>, BB calls $2.75, Hero calls $2.

Flop: ($9.10) 6/images/graemlins/spade.gif, 4/images/graemlins/heart.gif, 8/images/graemlins/diamond.gif <font color="#0000FF">(3 players)</font>
BB checks, <font color="#CC3333">Hero bets $5.5</font>, <font color="#CC3333">Button raises to $21.25</font>, BB folds, Hero?

Was my mistake not pushing preflop, or is that spewing? Does this look like a decent play, and is calling out of line to his push?

This isn't really a "safe" board since you flat-called preflop, you don't really know where you are. It looks like he has KK-AA here.

I would definitely 3-bet to 12 preflop, and probably fold to a 4bet.

as played c/f the flop. after flat-calling preflop you really don't want to continue with QQ unless you hit a set. (against an unknown)
