It is possible that you are right, but I just don't feel that folding here at the river is a way to make money at stud. Plus, if you make folds here, the smarter player will be betting you out of pots, hand after hand. Yes, you showed strength on fifth, but this looks like one of those instances that you just have to call, given that it looks like seat 7 is not going to call river. There seems to be more reasons to call here than to fold.

Also, i would prefer a call on fifth rather than a raise. It does not look like anyone is folding here and it is not clear that you have the best hand at this moment. You're stuck in this hand, but I think you need to make it as cheap as possible for you to play this out. Your hand is mediocre.
