3r late stages ATo in BB

[Supwithbates]

down to 3 tables, 24 runners of a field of 2600.
Unknown is moved UTG to my left, with a stack of 375k. I have a stack of 650k before posting, and post BB of 20k.
UTG minraises to 40k. Folded to me, with ATo, I call.
Flop comes Q95r. I check, UTG checks.

Turn comes an offsuit ace. What's my plan? Pot is ~100k, effective stack is 330k. No reads, but the level of play in general seems to be nitty and its unlikely he will bet without an ace.
I led for 40k, opponent minraised, and I folded. Is that standard?

if your going to bet ...bet 75k atleast.. min raise he could have 99 or 55 ... i hate min raises and i would prob. re-raise if he wasnt utg

It's standard from where you're sitting.

Though I agree with wulf, the probe bet on the turn was not a good play.
