I am really unsure of the following advice and would like to hear from some more experienced players on this.

My thought on this however is to fold. You have UTG+1 still to act so there is a good chance he will cap, practically forcing you to pay 3 more BB to see this showdown. Considering you do not have the nut flush here your flush is discounted, also with the board pairing up your flush is discounted even further. This looks like a slow played set that hit a boat. I also think their actions follow the thought of "a bettor can be bluffing a caller cannot." If this was HU I would advocate capping this. Again I hate to tell someone to fold a flush, but here this action just looks to menacing, and the pot is not terribly big.

Again, I am not sure on this and would like to hear some feedback. Is the line I'm suggesting too weak?
