how bad was this?

[bender]

Party 10/20 6-max.

UTG I have no stats on but has been a little too loose so far i think. BB is 31/16/1.6

UTG raises, i 3-bet with 77. BB and UTG call.

Flop: KQ8 (2 hearts).
BB bets, UTG folds, i raise, BB calls.

Turn: Ace of spades.
He checks, I bet, he calls.

River is an offsuit brick.
Check, check.

Thanks
