I think that pre-flop this is either a 3b/call, shove or a fold spot.  3betting commits you to the pot (putting in 1/3+ of his remaining stack if you reraise to 7bb+), so 3b/folding is out of the question.  But, if you're willing to 3b/call, you might as well shove as this gives you the most FE.  A call is not as good of an option:  If you're set mining this is at the top of the 5/10 rule range (1,600 to call with 17,701 behind for 9%), so it's marginal.  If you're calling for value, that makes it difficult as there are lots of overs that will flop, and you're playing OOP against a player that you don't have much of a read on.

As played, donking the flop for 4bb (instead of c/c) could've netted you the pot and you could've folded to a raise.  C/f would've been preferable as I don't think you're calling to float and take it away on the turn, and you're probably not calling for value.  It looks like a call for the hope that he's got nothing and will give up the t and r.

I would fold the turn to his overshove.  He made a standard cbet, leaving him with just over a pot-sized stack for his turn play (he should've cbet 2/3 pot for FE and to give him a better t shove stack).  He may not have been thoughtful enough to realize this, and upon seeing this mistake, instead of making a standard t cbet his only option was to shove, as anything else would've left him with too little on the river.  He could've been doing this for value or a bluff, but either way it's too much to call in the hopes that he doesn't have a K, 22, 55 or 99+, or even two overs and a fd.
