Boring 10/20 Ac flush but what's your default river line?

[HoldEmKillah]

In THIS (10/20 aggressive) game against a very aggressive player what is your standard river line here? Seriously I feel like an idiot asking this question but I know the 10/20 plays way different especially sh'd. I have found that 10/20 4-handed or less is just plain wacko. I'm adjusting ok I think though and learning a LOT. Anyway...

Check and hope he bets/bluffs then raise?
Bet weak and hope he raises/calls with weak holding?
Bet big and feign a bluff?
