Villain is 33/22/4 over only 87 hands. As soon as I made the river bet I thought "Fuck, what do I do if he c/r's me" and he did, the question is if I'm ever good here since the only play that makes sense form his viewpoint is something like 78 and has me on the flush draw where he can check and expect me to bet when it comes in on the river.
