QQ, the first time i wear the nit hat at a limit table

[shootaa]

so, I've been playing about 35/28 or so over the last 120 hands at the table and have a generally solid / aggressive image, making thin value bets like I do and all, then this happens... (6 handed table).

UTG+1 is 24/17/2 over 121 hands w/ a wtsd% of 34 (little nitty).

SHOOTAA ?

I'm thinking if I had JJ i would CC, because I think I have 6 clean outs most of the time (still too thin probably), or KK I would've 3 bet the flop obv (which I should've done anyways, and do vs most, this guy is such a nit that i had planned to show it down until his range got kicked in the face by the turn card. Soooooo, check-fold?
