Fancy play

[ST069]

You don't have much informations about these two guys here. If that raise is for value than, IMO a call is way better coz with that flop the only good drawing hand is 89 and than Utg is more likely to have a pair (but the coldcall on the flop can make you think that 89 is precisely his hand). If you have bt beat why do you want Utg to fold a hand that could have call you without that double bet.
If you really think that UTG is on 89 what do you think BT can have bet on the river and fold to a raise? I can't see much hands, maybe: QT, JT, AT even if i think that he probably have checked these ones on the river.
