Donkfold river?

[synbad13]

Seems like the TAG probably has a flush draw or a set.

It seems to me like the EV is probably strongest when you Bet/Fold (I don't think he's going to bluff raise the river... that would be pretty out of line for almost any player).

However, because I seem to be incappable of folding a hand like this on the river, I normally just check/call.
