SB: 24/21 3bet: 8,5 FlopCbet: 89%  (164 hands)

Hero (at the table): 27/23 Fto3bet: 60 UTG rfi: 33

Preflop: His 3bet range may not as narrow as in a standard UTG v BB situation. {AJs+, KJs+ TT+}

Flop: I think it's a standard flat because of his "wide" range. 

Turn: checking back is the only option because we can't earn money against weaker hands, and can't fold better hands.

River: My perceived range is Tx, Kx, TT-QQ, AQ, so I don't mind He shots another bluff barrel after He skipped the turn cbet. 

Is fold okay in this case?
