Hello everyone. I was playing 25nl regularly on stars for a while but recently left there (long story) and decided to make the change over to Full Tilt. love the software and a less traffic i don't mind. Now I seen a team pro member from stars named xflixx do a grinding up challenge in the micro stakes. Since I have never really done any real poker challenge for myself besides hitting the next star level i decided i would give it a shot. I started with a $80 bank roll and started at 2nl 4 tabling. When first starting off i was doing alright. got it rolled up to $120 in just over 1 day of grinding then hit a string of bad luck and built it back up to $200. using a 40bi rule(from the challenge) I jumped to 5nl. But im getting frustrated. I feel like I'm getting bluffed allot but still cant call there bet. have ran into some unfortunate coolers and nothing but a string of bad luck.

IDk if its me and my game? Anyone get through these micro stakes before or do a challenge similar to this? Im noticing allot of short stackers and have a tough time playing marginal holdings against them. 

One scenario i keep running into over and over is say If villain raises from MP and i call from the button. Villain makes a pot sized bet and all i got is a gut-shot or a FD or maybe 2 overs. I have a hard time knowing how to continue.

And also at these stakes should I be playing real tight in the blinds and not worry about defending blinds unless with premium holdings or should I practice on defending blinds more liberally?
