The thing with 1/3psb CB OTF is it relies on having some fold equity, so you're accomplishing what a larger bet would do but for less money. It is important to do this with hands like TPTK as well as when you miss on non-wet non-middle card flops. However, your hand here is strong but fairly vulnerable. Vs a villain who 3bets wide, and very likely is floating IP with air in order to bet turn after CB otf/ check turn, he could be doing this with a very wide range. And vs hands that won't fold, there are the few that beat you, but there are a lot of other pairs that will call. So I would exploitatively bet larger, as much as 2/3p. As an aside, CB flop/check turn is usually a -EV line, so you want to do your best to avoid having to do that with hands you intend to fold to a bet after checking. Preventively BTW, not once the over card comes.

Any stats/reads?
Readless, I'd say it's a fold OTR. Looks like a flopped set, not too many 2 pair combos out there, would be hard for him to have a T. Even semibluffs are hard for him to have. There's A3cc, A4cc, 98cc which might play this way; 64s which IMO would be more likely to x/c than x/r OTF, 34cc i guess is possible too. Once you call turn though, there's really not much you could have other than some medium PP, or Tx, and you're certainly not folding Tx OTR, so the shove OTR really looks like it's for value. Higher PPs wouldn't play like this either. You do beat maybe something like 57 that flopped 2 pair, but again i don't think villain would be bombing river once he gets counterfeited.
Unless... he's a total maniac in which stats/reads would be essential.

To continue on what Brokenstars said, you should aim to get some value from a call from SB too rather than isolate.
