What hand is calling me that I beat? UB 80/160

[IndieMatty]

I think a major leak in my game lately has been betting rivers, when no possible hand is going to call me that I beat.

80/160 UB.

7 handed. UTG is fishy and on a roll. I'm guessing he's playing about 70% He limps UTG. SB completes. I do the virtual knock on the table with A9o. Anyone put a raise in here as I'm relatively certain I have the best hand?

Flop is k48 all spades, I have no spades. SB checks; I check.

One thing about UTG is he'll rarely bet if he has missed.

Turn is an Ace of hearts. I bet UTG calls, SB folds.

River is a Ten of clubs.

I bet, and get raised. Easy laydown? Small Pot? QJ with a spade?
