I have recently started playing huplo, while my first 25k hands I ran way above EV at 13bb/100, it seems that variance is catching up. My biggest problem is when I see a draw got there I check. I feel that my opponents are picking up on this and are betting with air based on my showing weakness. Now when I have 66xx it is safe to say that if villian is repping a straight on a 457 board he is likely bluffing. However, how do you handle cases where you want to know if its safe to rep a flush? I have seen cases where villiians try to rep nut flush holding the ace but low mid stakes most people are calling with all flushes. Any insight would be appreciated on how I can better handle this.

Thanks
