I wonder how frequent you guys see an over-bet jam on the river as a bluff?

From my own limited experience, I have rarely seen any big over-bet bluff (OTR) in low stakes in my local casino, hence in the hand below, I wonder whether we can overfold?

1/2. Friday night. 8-handed. Hero just transferred to this table for 5 minutes so no ideas about the table dynamic.

UTG+1 limped 2, 4 limpers, until we saw red Kings on the BB. We opened to 20. UTG+

Well I am not sure whether this villain should be defined as OMC - first time seeing this older player in the casino, not sure he plays regularly, and he seemed wider than average OMCs.

During the 20 minutes we played together, there was one hand hero opened KQss (4bb) from LJ, villain called with 95cc from BTN. Flop came Q98 two tones, V calls my 3/4 pot bet with middle pair crap kicker no FD. Turn came an offsuit 5, V called my 2/3 bet. R
