Raise the river?

[Arrion]

Setting: 3/6 live 9-handed Hold'em game at Casino AZ. The table is very loose passive, with 4-6 players seeing the flop most hands. UTG+1, the principal villian in this hand is typical for the table; no specific read.

Hero is dealt A /images/graemlins/spade.gifJ /images/graemlins/diamond.gif 2 off the button.
UTG folds, UTG+1 calls, MP1 folds, MP2 calls, Hero calls, CO folds, Button calls, SB completes, BB checks. Six players to the flop for 6 small bets.

The flop is QQT rainbow. UTG checks, UTG+1 bets, MP2 folds, Hero calls, Button calls, SB folds, BB folds, UTG folds. Three players to the turn for 9 small bets

The turn card is K /images/graemlins/heart.gif, putting 2 hearts on the board.
UTG+1 bets, Hero raises, Button folds, UTG+1 calls. Two players to the river for 8.5BB.

The river is 9 /images/graemlins/spade.gif. UTG+1 bets, Hero calls. Final pot 10.5BB. Results to follow later.

Feel free to comment. When UTG+1 did the stop and go after the river I just called because I was worried about him filling. Should I have raised and only slowed down if 3-bet? Also feel free to comment on the flop call. I'm pretty confident that was right. I almost had the pot odds to draw to the gutshot, and can also consider implied odds and the small possibility that UTG+1 was betting a pair of 10s making my ace and jack outs good.

I think you have to raise the river and if you are three bet then call. Someone could have filled up especially with the broadway board but I think you still raise.

I would have folded on the flop after the UTG+1 bet.

You are most likely dominated, if not, then drawing dead.

I don't like the flop call. You've got a gutshot with a high pair on the board against five opponents. I think the pot is too small and too great a chance that your hand won't be good if you hit. That being said, raise the river, call a 3 bet.

UTG+1 turned over QJo for the smaller straight and MHIG.
