fold flop and it's not even close.

Turn is borderline.
Doing a quick aproximation: the chance an opponent has a spade given no information from betting patterns is < 1/3

If he has a spade, it's probabily higher than a 7. Cards called from the BB mostly contain cards higher than 6. So id estimate >50% of the time if the opponent has a spade, it will be better than yours. So id estimate your outs are good a little greater than 75% of the time.
So ~6 outs for the FD, and id estimate you have about 1-1.25 outs to the ace.
Very little to no implied odds because your paying off about half the time on your ace and wont always get payed off on your spade, but are always paying off a better spade.

Getting 5.5 to 1 with aproximatly 7.25 outs is a borderline situation. It probabily doesnt matter what you do. Also some people would always pay you off with any pair so you actually have slight implied odds, in which case I would call. Also I just did a very quick aproximation on you being good when the flush card lands. So maybe you are not good 75% of the time, maybe you are more.


River raising is not a good idea without a solid read.
IE if you convinced he would always pay you off with any pair and would never 3-bet spazz bluff, it may be okay.
Contrary to popular opinion, there do exist opponents where I would raise this here.
