OESD & Trip 9s - Raise, Call, or Fold?

[TomBrooks]

No reads. I think I should have checked this flop, but I think I bet out reflexively because I've been playing almost all 6max for a while and I would bet out in 6max because the pair of nines is more likely to be the best hand at the moment. That being said ...

How would you play this postflop?
