Ok villain is 0/0 through 6 hands so nothing to go off of really.

I have only been at 50's for like 3 sessions and so far it seems like you get raised on the flop A LOT more, so when i get raised here i think its with a pretty wide range (flush draws/Kx/sets/mebe turning some PP's into bluffs but prob not)....When the turn completes the flush i think i am significantly behind and i am going to be facing another bet on the river, easy fold?....what about on the flop???
