I call and check/call non-flush/straight river if he's that terrible. Against a reasonable tight player this screams SET to me, but against a donk it could be any king, diamond/spade draw, gutshot or some random pair, as well as nothing at all.

A case could be made for raising to protect against diamonds, spades and straights, since this is one of the ugliest boards to play on with TPTK but I'd prefer to keep the pot small.

I guess folding would be alright, if a tad weak against the opponend described here IMO.

The reason I prefer C/C over B/F on the river is, he might very well bluff missed draws which there's a ton of out there.
