I dont like badugi much, but I would say that not a lot of people actually bluff in this game. When they have it they bet, when they don't have it they don't bet. Mainly this is a limit game so bluffing isn't always the best option. But id say play according to how others at the table are playing. You don't want to fish a lot, but you also dont want to let others run over you. Get really aggressive with your made hands, and hands that you know you're ahead. A lot of these draw games are a bit tilting, so good luck to those that like to play it.
