I say go with it. You block the full houses and can fold out the nut flush draws that picked up top pair. I think you get 65 to fold sometimes too as well as some 9s. I think its +ev and if you want to get better these are the kind of plays to try once in awhile. Also the worst thing that happens is you lose $320. Good for you for trying it. If you were in villains spot what hands would you bluff catch with?
