$10 NL 86o Interesting River Spot?

[QandA201]

I wasn't sure about this. I only have 22 hands on villain, but he is 55/18 through those 22 hands, probably irrelevent, but in the interest of full disclosure, I thought you should know. Anyway, I thought this was a semi-tough spot on the river. Standard?

The Rivercard sucks but there is to many money in the Pot to fold against a 55vpip Villian
