For the first hand, definitely just call instead of raising. You're not going to get a loose player (as per your read) off any top pair or such, so call and give yourself a chance at the nuts. Also, you have two overs, which in this case aren't as clean since they complete straight draws and could make him two-pair.

For the second hand, You've raised PF so hopefully you can discount that he has a 7 or 4 in his hand. On the river, I'm betting 25-35$ hoping for a call, but by the way he played it, it looks like AK or something that all small-stakes donks chase with.
