What's are your views on slowplaying at uNL stakes?

Here's a hand from earlier where I just wasn't sure about what line to take postflop:

PokerStars No-Limit Hold'em, $0.02 BB (6 handed) - PokerStars Converter Tool from FlopTurnRiver.com

CO ($5.07)
Button ($1.18)
Hero (SB) ($4.98)
BB ($1.76)
UTG ($2)
MP ($3.03)

Preflop: Hero is SB with Q, Q
1 fold, MP bets $0.06, CO calls $0.06, Button calls $0.06, Hero raises to $0.20, 1 fold, MP calls $0.14, CO calls $0.14, 1 fold

This was my second hand at this table, so I have nothing on MP or CO at all (and of course they have zero on me), so I'm thinking default ranges would be:

MP Range - JJ-22,AQs-A2s,KJs+,QJs,JTs,AQo-ATo,KJo+
CO Range - JJ-77,AQs-AJs,AQo

prior to my 3Bet

Flop: ($0.68) Q, 2, 9 (3 players)
Hero ???

...if they've stuck around with the majority of those ranges there's a good chance they've hit, and so I'm thinking Check/Raise

Pls. feel free to tell me i iz stoopid feesh
