tricky river spot

[jj12]

Opponent is 28/7/1.5 over 25 hands. In the hands we played, he has folded to my cbets 2 times and 1 time I put him all in on the river and he folded. So it is possible that he is getting frustrated with my aggression. I expect to be called lighter and it is more likely that he tries a bluff with the king of clubs.
