200s early on with an overpair

[Jdanz]

like 3 hands in i have 9s in late position, sorry no reads, but just what are the thoughts going through most peoples heads on this flop/turn.

10/15 blinds, UTG makes it 45 called by UTG+1 and me in LP, everybody else folds.

flop comes 552

UTG checks, UTG+1 makes it 100 (has me stacked) into a pot of 160.

I raise to 325 UTG folds UTG+1 calls

I planned to fold to a raise here as UTG+1 cold call looks like a pocketpair to me, and i don't think a big ace is going to get frisky here.

turn is a 6. UTG+1 checks i push for 630 into a 800ish pot.

thoughts?
