A-high, 4-person turn

[Redd]

6m 0.5/1 Bet365 game. I'm fairly new to the table, can't really tell who's tight and who's loose yet but I have figured out that the table is fairly aggressive by low-limit standards.

2 limpers, I complete A[img]/images/graemlins/spade.gif[/img]8[img]/images/graemlins/heart.gif[/img] in SB. BB checks.

Flop comes 6[img]/images/graemlins/heart.gif[/img]4[img]/images/graemlins/diamond.gif[/img]5[img]/images/graemlins/heart.gif[/img]. BB checks, I check, and it gets checked around.

Turn comes 6[img]/images/graemlins/spade.gif[/img]. BB checks. Hero's up.

Does anybody every take a shot/value-bet in these situations? I often wonder if I should be playing these more aggressively.
