tpwk from the bb short-stacked

[Isura]

I think I misplayed this badly. My first thought is to open push the flop, but I decided to make a dumb probe bet instead. I had notes that this opponent is capable of raising the turn with an underpair, or even worse, so I think my hand still may be good. Is checking the turn better here?
