55 flops OESD vs semi short donk

[AZplaya]

Villian in this hand is 48/14, typical NL$50 donk. His range for lol minraising from the SB is pretty wide. Not sure how much fold equity I have, maybe 10 - 15%? Is our hand/draw strong enough to get it in on the flop?

It's an aggressive move on the flop. About the only time you can shove here is if you don't put your opponent on a set as in that case you would be a 3-1 dog (75-25). Theres still alot of hands that beat you here which doesn't make your hand strong enough to get it all in IMO. I'm going to assume he had an over pair that had you crushed pf and you got lucky after he called your all-in.

I don't like this too much. Do you push here with sets etc too?
