Personally, I don't think so. The pot is already large, no need to get tricky and try and squeeze a few bets out of them. That third heart is scary if they don't have a flush, and it can easily be checked around.

Without an aggro player here, there's no need to go for a check-raise. Heck, even with an aggro player, bet out and hope they three-bet. Either way, they want to call, let them call. I say nice hand. Also, on the table you describe, I think A8s is fine to play preflop.
