I've played nearly 25k hands in 6max 2NL in the past two weeks running pretty poorly.

After trying to look for some of my leaks I've noticed through holdem manager leak buster that I'm about -64.45 bb/100 and I'm sort of confused by what I might be doing wrong. As to this point I've mostly opened the action with every suited aces from all positions, 3bet/squeeze vs a BTN or CO open when in the SB, and 3bet/squeeze vs a CO or HJ open when on the BTN. I'm still kind of confused with how to play suited aces in the BB so thats been all over the place with either defends or 3Bets.

I'm kind of new to poker and this site in general but maybe someone can give me some tips and point out what I'm doing wrong...

Thanks
