Hero?

Villain is a regular playing 23/18. 3bet vs SB is 8% Fold vs Cbet is 60 % in position. My SB open is 40%.
Villain played this session fairly agressive but overall he is on a passive side.
We had some 3bet/4bet war in this session earlier.
He sees me as a regular,maybe on a nittier side.

My thoughts on the hand: On the Flop we are oop with a weak holding and low SD value my bet is a protection bet.
Turn is a great barrel looking card he has to know it,so it is a no brainer bet IMO.
River bet or check? Why? If bet,what size?

Would you play the hand differently until the river?

Thank you in advance!
