Weird overpair hand

villain is 52/3/0.05

Again a big fish, lots of callers preflop so it was a pretty big pot on the flop. I checked the turn because I was just scared of a set really and a few two pair hands. On the river I decided that I would bet $25 and fold to any action.

I generally check the flop against that many. As played, I check the river if i've checked the turn, not keen on the c/c, lead river.

so if you checked the flop you'd bet out on turn and river?

yeh depending on cards obv
