eh, i fold out of turn on the turn, because i don't need the stress.

No experience playing at 1/10th these stakes, but seems with him asking you how much you have left, thinking and flatting, he on the surface is playing like he has a draw, possibly a weak one. He figures he can maybe take the pot away on the turn if he doesnt hit, and in case you do have a monster here ( i would guess that if you had a set here you would play it like this because of the board?) he has odds to hit his gutter and take down a huge pot. But that seems like low stakes thinking, so he could be going one level above that and doing that with strong hands. OR he could assume you would know THAT and be doing this with a draw, because "a smart player would never do this with a draw"

Pot on turn is ~800, i guess i would bet 2/3 pot or so on any diamond, A or 5 and call a shove (i assume we are going to get c/r on the turn a lot), and check behind all others assuming he checks. Im not sure what i would do on the river here if i dont improve. I guess you could call because he knows we dont have a big hand if we check behind on the turn, so he is going to VB his strong hands and bluff with air, missed draws, so we may have odds to call.

WTF i dont know i play 1/2

Samo is really freakin good. i wouldnt be especially inclined to get involved in a big pot with him.

his range is wide here. sets, FD's, one-pair hands, two-pair hands. im not sure how often he has complete air here OOP, but i think its going to be at least some % of the time. based on what i've seen posted from his online play i don't think it is at all a guarantee that he's going to raise a big hand/big draw here.

he's also proven to be very very able to fold near-nut hands when he thinks he's beat....so im not sure you're going to get paid if you hit trips or a runnered flush.
