How do I maximize the damage here?

Opponent is 28/11/3.7 over 1k hands. We don't really have history. His river aggression is 4 but I don't have enough of a read to know that he'll auto bet if checked to, so likely not.

What kind of action do we do here... C/R, bet x?

I like either a check-raise or a lead of $29.

I think leading for $29 is probably best here.

triple post yay!
