T8dd 1/3 with $6 straddle river bluff raise

So villain is loose pre, limps etc but other than that i dont really know much. We did play a hand a few sess ago where he donked turn when i had KK on a Q high board where he made a straight then river came a flush completing card and he x to me so i vb thinking he had Q - he tank called. And he’s caught me bluffing smal before.

i do think he won’t 3b his straddle here with a trash hand - most like top 15% or whatever. 99+, AQ+

so i raise to $20 on button, he raises to 45 on straddle, i call. We are $900 effective.

FLOP Q23hh/d $94
xx

TURN 4d $94
v bets $40, hero calls

RIVER 6x
villain bets $60, hero raises to $180

thoughts?
