Flopped set . . . uh oh

[Taraz]

I'm not sure if the preflop call was correct, but in any case how was my postflop play? I'm thinking I should have either checked the turn or bet more, but I'm not sure. Suggestions?

This is a clear fold preflop. Otherwise I think it is fine, maybe bet a bit more on the turn. Don't consider checking the turn, if he has an ace, he should be ready to pay you.

What do you guys think of pushing this on the flop?

(too early for such confrontation, but still, he should be ahead most of the time, no?)
