Is this line optimal?

My question is, can I get more from him? What type of hands do you think he has? He is a 25/6 with a 3 aggression rating. I smooth called the flop because there are not many draws and I up against an aggro opp. I figured he would fire the turn.

What kind of hand do you put him on when he calls my turn raise?

you can bet more on the riv (where are the stack sizes), it looks like he has a king , if he called a big bet on the turn he'll probably call a big bet on the riv as well...

We both have full stacks

I'd go 40 on the river as played.
