Preflop:
Hero limps, half the table limps, Button limps, blinds complete/check

Flop (7SB): 3[img]/images/graemlins/diamond.gif[/img] 4[img]/images/graemlins/club.gif[/img] 8[img]/images/graemlins/club.gif[/img]

Hero bets, all 3 of the middle players call, Button raises, Hero ???

Raise again, or call hoping they all call and will call more on the turn?

I would just call here. You don't want to knock anyone out, but if you think they'll call two here, go for it.

I think 3-betting is good here

there is a fair amount of $ in the pot, and you would like anyone with a better ace to fold. if you had something like 2[img]/images/graemlins/club.gif[/img]3[img]/images/graemlins/club.gif[/img] I think a call would be better, but here you'd like to maximize your chances of winning this already pretty big pot. and if they call you have a draw that will almost definitely win you the pot (barring a full house).
