Top two on a scary board vs Zeejustin in Caesar's 10k

[adanthar]

In any cash forum, everyone would be screaming to get it in. Except this isn't cash and if you get it in vs. ZJ, you have 4 outs, so...hmm. obviously a turn c/r is bad. a check/call is good if he's going to bet, but how often will he bet a naked 8, a king or a bunch of other stuff on this board?

so I like leading the turn. but since we checked and will presumably call, what's the river?
