losing to 6 aces/beating 5....keep plowin ahead?

[yesplease]

1/2 nl at nyc club. table is 9 handed.

effective stacks: $300

hand occured within 2nd orbit so i dont have any substantial read. this is my second open raise since i sat. first one ended in me winning on c-bet. HJ hasnt been too active in 15 hands ive sat.

i open in MP to $10 with A [img]/images/graemlins/heart.gif[/img]T [img]/images/graemlins/diamond.gif[/img]. HJ calls as does BB.

($31) flop is 7 [img]/images/graemlins/spade.gif[/img]A [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/club.gif[/img].

BB checks, I bet $20, HJ calls, BB folds.

($71) turn is 7 [img]/images/graemlins/spade.gif[/img]A [img]/images/graemlins/diamond.gif[/img]4 [img]/images/graemlins/club.gif[/img] [9 [img]/images/graemlins/heart.gif[/img]]

i check, HJ bets $30, i call (????)

what is your plan on the following possible river cards...reason?
1)T [img]/images/graemlins/heart.gif[/img]
2)8 [img]/images/graemlins/spade.gif[/img]
3)J [img]/images/graemlins/diamond.gif[/img]
4)A [img]/images/graemlins/club.gif[/img]
