Villain is unknown but no out of line, according to his stats and small sample size.

Flop
Being this deep I decided to slowplay and let him bluff since I block a lot.

Turn,
Is it reasonable to check/call here, in the hopes to get a check/raise on the river?
Leading the river is also a possibility if I check/call.
The standard line seems to be the check/raise but I'm curious whether we should do it 100%.
