400NL A-10o

Villain is a donk.

didn't want to donk bet the flop since i didn't want to fold if raised, and anything other than a minraise by villain and i would have folded.

The turn was a great card so i lead out, though any card that wasn't a 2/6/10 and i would probably c/f turn.

Bet sizing on the turn ok? What size bet should i make on the river?

I often 3-bet this pre, depending on reads on Player 2. I guess I'm ok with the flop c/c given read on villain. I like the turn lead. Now I lead the river ~1/2 pot, trying to get value from worse tens.
