100NL (6m):River play with this rivered full house?

[CybrPunk]

Villain in this hand is 55/10/1.8 over 153 hands. I probably played earlier streets sub-optimal but I had seen him minbet with total air and fold to raises almost every time so I figured c/c'ing him was the best line with my hand, trying to not play a big pot, until the river card came...
