FR25 Zoom 3 bet pot cbet called, fish donk shoves paired turn 2

He is a recreational player judging from his stats.

Therefore flop cbet in itself isn't getting enough folds, but if you are planning on barrelling many turns then I think cbet, cbet is fine.

Equally checking back is fine. If this guy seems quite raisy post flop or spazzy post flop, which it seems he is, then I am more inclined to check back. But if I don't know this then I think cbet with plans of cbet turn is better.

Facing a turn donk is really odd.

This looks like 2x which in a normal call raise will only ever be A2s, but rec players might call A2o, K2s as well. Obviously this is a small amount of hands.
This could also be 9x,8x, AQ or pocket pairs deciding that they don't want to check call, or have turn checked back and face an overcard on river, so in their mind they shove because they think they have an ok hand relative to the board. They aren't thinking about your range.

It would surprise me if it was a bluff. I rarely see check call, donk allin bluffs. But I rarely play 25NL, so maybe it is more common there. Its not impossible that he has nothing here, but if this is the case then you will notice him being super aggressive on other boards too, until he loses his money, hopefully in a future hand facing you. I would isolate him a lot if he is agressive enough to donk ship nothing on turns like this, and I would pretty much never fold any pair vs him.
