kinda confusing he´s betting so weak, but i wouldn´t do anything different.

raise river - laggs (especially bad ones) never believe you have anything - and that's a terribly value-free bet by him on river if he has a straight or boat.

easy river raise. Missed FD probly.

easy river raise. Missed FD probly.

If he has a missed FD, whats the point in raising? He cant call.

I think you played it fine.

ps. the small bets mean he either has a huge hand or a weak one.
