Personnaly, I would fold this one with no doubt

Better spots, for sure.

I'd probably bet/fold the turn, to get value from random 7s and T8-98. You can't call this river ever.

easy fold. You can't beat much

[Waingro]

Don´t check/call the turn, if you check and he bets pot fold really fast. I would probably bet/fold. River is lol fold.
