implied odds in BB

[willie24]

say it's a 5 handed game

UTG raises
folded to button who reraises.
SB folds
you have 7 [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/heart.gif[/img] in the big blind

call 2 bets or fold? I feel like this is a straightforward question that there should be an easy answer to, but I don't know what it is.

assume opponents are strong shorthanded players: adaptable but generally aggressive preflop and loose postflop.

thanks
